A warm welcome to all of you. I am
delighted to address you in this
anniversary yearbook, looking back at
the first 25 years of RadTech Europe. It
all started with a common vision of a
number of pioneers who wished to
promote UV and EB technology, and to
strengthen the collaboration and sharing
of knowledge within the industry.
Over the past 25 years our joint efforts
have been an important factor in the
success the technology has seen thus far.
The UV and EB protocol, the deinking
project, the guidance on safe use and
handling, our various seminars and our
advocacy efforts at the European level
concerning mercury restrictions, the
rules for eco-labeling and other topics
have helped raise the profile of UV and
EB, and defend its position where
necessary. Of course, the conferences
have been our mainstay, delivering
leading technological content and a rich
platform for discussion every two years
since the inception of the association.
We can be proud on what has been
achieved so far.
These results are thanks to the tireless
efforts of you, our membership. We have
had various champions for our
technology over the years, pouring their
time and energy into the association,
organizing events and opening new
venues for energy curing. Not for
personal furthering, but for the wish to
share knowledge on and promote the
growth of a technology of which they
were deeply convinced. Looking
around, quite a few people from the
beginning are still here, and even now
involved. 25 years on, that is impressive.
Every contribution to the association
helps, no matter how big or small. As
with many things in life, the more you
put into the association, the more you
will find it gives back. It offers the
opportunity to look beyond the borders
of your own company and share ideas
with others in the industry. Share your
knowledge, be part of a committee, help
set up a seminar or a small project.
Inform the association of issues you
have encountered or help us establish
contact with an association or end-user
that you think is relevant; let us know
how we can improve our events. All of
these can help RadTech Europe grow
and make us more effective in
promoting UV and EB.
More and more, ties with other
associations and with the Commission
will be instrumental to this. Over the
years, we have shifted our focus from
delivering technological content to our
membership, to reaching out to
potential end-users and other
stakeholders. The PR campaign, our
seminars and our new series of
discussions with related associations,
such as CEFIC, EuPIA and ECMA all
reflect this.
The original vision is still there; to create
a large market for everyone, to face the
challenges that one company cannot
handle alone and to present a united
front to other technologies and
stakeholders. The challenges have
remained; whilst UV and EB have seen
significant year over year growth in
these 25 years, there is still plenty of
room to grow its share in the total
coatings, inks and adhesives sector. In
some applications, such as wood
furniture and narrow web, it has
become the technology of choice. In
others, technological challenges, cost
considerations or simply unfamiliarity
with the technology and its merits have
limited its impact thus far. Here, we as
an association can use our collective
weight and knowledge to open new
doors.
Thank you for supporting us over the last
25 years, and I am looking forward to
take RadTech Europe into the next 25!

25th Anniversary Conference – a brief look back
Lausanne, Basel, Barcelona, Nice, Berlin,
Munich, Edinburgh, Vienna. What might
read like an itinerary of a backpacking
Euro-trip are actually just some of the
locations that the RadTech Europe
Conference and Exhibition has visited
over the past 25 years. With 25 years
come a wealth of stories and memories.
The biennial Conference and Exhibition
remains the signature event of our
association, and actually predates
RadTech Europe itself by 5 years.
Origins of the conference
and the birth of an
association
In the early 1980’s, a number of European
companies working with UV and EB
technology recognized the need for a
platform to promote and share the latest
advances in the rapidly growing domain.
At that time, no other European event
existed in the coatings, inks and adhesives
industry with a singular focus on radiation
curing.
Initiated by Jürg Seidel and a number of
others, a series of 3 events – the so-called
European Radcure Conferences - featuring
academic and technological
developments in UV and EB were held in
Lausanne, Basel and Munich from 1983 to
1987. A major achievement, and one that
could not have been realized without the
energy and passion for the technology of
the pioneers involved.
The positive reception to these
groundbreaking events testified to the
industry demand for collaboration,
knowledge sharing and promotion in the
radiation curing arena. As a direct result,
RadTech Europe was founded in 1988 in
Basel, Switzerland to help further the
development of radiation curing in
Europe.
Evolution of the event
While RadTech Europe for many years has
successfully combined a technical
conference and a commercial exhibition,
the event started from more humble
beginnings. Initially the event solely
consisted of a technical conference.
However, attendance quickly rose as the
event’s reputation as pioneering
technological platform and meeting point
for the industry grew, helped by doubledigit annual growth of UV and EB
technology.
It wasn’t long before participants
requested a commercial platform to go
hand-in-hand with the conference,
leading to the introduction of tabletops,
where companies could present their
products and services. This was eventually
led to a fully-fledged exhibition as the
association entered into collaboration
with Vincentz Network, the company
behind the highly-respected European
Coatings Show and a number of leading
publications, such as the European
Coatings Journal.
Even today, both this valued partnership
and the clear distinction in organizational
responsibilities remain: Vincentz Network
is responsible for the exhibition and the
organizational aspects of the conference,
whereas RadTech Europe is responsible
for the conference content and format.
The shift towards a slightly more
commercial event was not without
resistance from some members that
preferred to a purely academic
conference. Over the years, the exhibition
has become an ingrained part of the
congress and steps have been taken to
further expand on it. Inspired by our sister
association Radtech North America, 2011
saw the introduction of a commercial
session on the show floor. While the
conference strictly allows technical
content only, these sessions offered
companies the opportunity to market their
products. As the sessions drew capacitycrowds, this is an interesting development
for the future, further widening the appeal
of the event.
Over the years, attendees have had the
opportunity to not only hear the latest
technological advances, but also to see
UV and EB in action. The Berlin
conference in 1999, aptly titled
“Gateways to new horizon”, had a
dedicated Application Centre,
demonstrating powder coating of MDF
slabs, label-printing and UV-curing of
silk-screen printing ink on PVC. In 2011,
an excursion was organized for attendees
to the Muller Martini Training Center
Presses in Maulburg, where they could
learn more about modern food packaging
printing using the VSOP web offset
printing press with UV inertisation and
electron-beam curing.
The most addition to the conference has
been the inclusion of RadTech Europe’s
General Assembly on the starting day,
offering members and other interested
parties the opportunity to get a report on
the activities of the association and the
plans for the next year.
While many things have been added to
the format of the event, some things have
(temporarily?) disappeared as well. Gala
dinners, one of the traditional staples of
the conference, have been noticeably
absent since Vienna in 2007. Originally,
this was due to the reduced format of the
2009 event in Nice. Faced with the
onsetting crisis and the restrictions on
travel in many companies, we had to
choose between either a two-day event or
postponing. When we elected to go ahead
with a trimmed-down version of the
event, this not only impacted the
conference. In the exhibition, most major
exhibitors chose minor booths and a
number of major suppliers even shared a
common booth to reduce costs.
Fortunately, with the economic tidings
turning, we have been able to return to
the tried-and-true three-day format. The
gala dinner, however, has yet to make a
return. Perhaps in 2015?

Innovation awards
2003 saw the first issue of RadTech
Europe’s Innovation Awards, with
laureates Plastlac Srl., Delo Industrie
Klebstoffe GmbH and Implanta AG. Goal
of the awards was and still is to recognize
special contribution to the opening up of
new markets and application areas for UV
and EB technology.

The Innovative Award
becomes the Paul Dufour
award
In 2003, the traditional award for best
conference paper was named after one of
the founding fathers of RadTech Europe,
Paul Dufour, in recognition of his
contribution to the growth of UV and EB
technology. Mr. Dufour passed away in
2002 after a life-long career in the sign of
the UV/EB curing technology and RadTech
Europe. He had been an invaluable part of
RadTech Europe’s Management Committee
between 1983 and 1993.
The award, this
year in its tenth
year, has become
the UV/EB curing
industry standard
of excellence
and is bestowed
upon the most
innovative paper
Paul Dufour
presented at the
conference. Given the fact that papers at
the conference typically number well over
a hundred, winning one is no small feat!

Memorable speakers
Next to technological papers, our
Conference has had the pleasure to
welcome a number of prominent keynote
speakers over the years, such as Mr. von
Weizäcker, member of the German
BundesTag, who explained on the role of
technology for sustainable development.
In 2011, Mr. Rademacher, member of the
club of Rome, revisited this topic, looking
at innovation and its impact on our global
living.
Major end-users have given their views on
UV and EB as well, with Mr. Hervé of
Nestlé taking the stage in 2009. He
explained the vital importance of the
complex supply chain in the food industry
and the diverse range of materials that
can come into direct and indirect contact
with food. He said, “Nestlé believes
collaboration and knowledge exchanges
throughout the whole value chain helps
ensure the very best in manufacturing
practices.” He added, “Nestlé believes
Winners over the years

radiation curing inks are an excellent
technology providing that the curing
process is well controlled.”
In 2005 we were honored to receive Mr.
Alain Adjemian of the European
commission, speaking about EU
Collaborative Research as a Mean to
Achieve Growth, and the role for our
technology.
This year’s conference will honor the
tradition with a keynote speaker of note,
Mr. Bellini of the Talent Foundation. In
line with the topic of the conference, he
will look give his view on current and
future developments, and how they might
impact society as a whole, and the role of
radiation curing in particular.
The more things change…
Looking back, a lot has changed when it
comes to the conference. In 1993, the
Conference even took place on a cruise
ship, sailing the Mediterranean Sea!
Whilst this might have sounded as a
wonderful idea, in practice it made
private discussions with clients next to
impossible and hasn’t been repeated
since. This year has seen the first time that
a conference location (Basel) was visited
twice in a row. The original idea here was
to set on a permanently fixed location,
facilitating the organization and
increasing recognition. However, with the
strength of the Swiss Franc versus the
Euro, this will be re-evaluated after 2013.

Some things haven’t changed over the
years: the RadTech Europe conference has
always remained the leading European
event for the UV and EB industry, offering
not only the insights in the latest
technological advances and innovations,
but also a meeting place for anyone with
an interest in the industry. We are proud
to have been here for the last 25 years and
are looking forward to welcoming you for
at least the next 25!

Markets and Materials – an Update
Radiation curing may not be a new
technology – in fact, it dates back as far as
the ancient Egyptians – but, as RadTech
Europe member companies demonstrate,
it continues to innovate, both in terms of
its areas of application and its delivery
methods. Indeed, today, both UV and EB
curing are enjoying a strong wave of
growth in usage, across an extraordinary
number of markets – as market statistics
clearly show. Coatings, inks, and
adhesives – particularly on heat-sensitive
substrates – are now benefiting widely
from a curing technology that is at once
speedy and environmentally friendly.
These are attributes widely appreciated in
industry today, and the key to a profitable,
successful future for our technology.
The establishment of RadTech Europe in
1988 was a timely response to the
growing interest in that technology. It was
driven by a desire to create a formal
profile for the industry’s extended value
chain, and to establish a pan-European
platform where members could meet,
share knowledge, develop joint themes,
and educate. By bringing together UV
and EB curing, RadTech Europe created a
strong focus on the concept of radiation
as a curing method per se, and provided
potential markets with a single expert
source of expert information.
Today, working with Lejeune Association
Management and with its head office in
The Netherlands, the association has
achieved a high-visibility presence in the
many end-use industries its members
serve and, through its new PR campaign,
is strengthening its media presence. Our
association’s website – established as
www.radtech-europe.com in 2002 – has
proved a popular information hub.
There is no doubt that radiation curing’s
current chemistry and technology have
secured its prospects – and the combined
creativity, technical expertise, and global
experience of RTE’s membership continue
to demonstrate their ongoing ability to
innovate at all levels of the value chain,
from specialty chemicals through to
equipment and process control.
Markets and materials
Looking at global usage of our
technology, the EMEA region – and
particularly the German-speaking
countries -- is today the largest and most
dynamic market for formulated products
using radiation curing. UV is the leader
for industrial coatings, representing over
50% of total usage today. The wood
finishing industry is one of the main
application areas for UV and EB, with
commercial systems in use since the
1960s. UV and EB coatings are typically
known for high gloss and body, whilst
offering excellent adhesion, scratch and
abrasion resistance. They are commonly
used for high-quality coatings in the
parquet, wood and furniture industry. This
is by far the biggest application area in
Europe for radiation curing, representing
39% of total usage in 2011.
The technology’s advancing 3D capability
has also made it popular for curing,
among other items, automotive and
electronic components, household
appliances, architectural components
such as concrete and on-site industrial
PVC flooring, metals – including cans and
steel industrial tubes -- and rigid plastics.
In the automotive and electronics industries,
radiation curing is increasingly contributing
to the efficient and cost-effective production
and finishing of metal and plastic
components (and interior parts such as car
fascias and, externally, truck axles) through
the provision of good adhesion values,
higher gloss levels or tactile finishes,
improved durability and scratch resistance,
as well as shorter processing times, reduced
emissions, and lower energy consumption.
While these are not high-volume markets,
they represent high value, and are not
generally cost-sensitive.
Industrial uses for EB curing have relied
traditionally on large curing units, but the
trend today is to much more versatile
small, compact emitters which can handle
a broader choice of tasks and deliver their
service in different working environments.
Similarly, the concept of ‘portable’ fieldapplied UV curing is gaining market share.
New markets with real potential which
are emerging for EB and UV technologies
include curing of membrane switch
panels, photovoltaic panels, glass and
windscreen repairs on cars; medical
disposables; dental repairs; and cosmetic
fingernail decoration.
Print and packaging
Where would today’s high-speed reel-fed
packaging and label printing market be
without the development of the tailormade radiation curing systems that do
away with the need for long drying tunnels
and conventional low solids, solventborne coatings and their associated
lengthy curing time? --Their ability to save
space, time, energy, and cost (particularly
in the packaging market, where
sustainability concerns are an especially
sensitive area) – is supported by the fact
that radiation-cured coatings can be
considered as environmentally-friendly,
contributing neither VOC emissions or
flammability. In fact, more than 46% of
European radiation curing takes place
today on printing inks and varnishes. It is
one of RadTech Europe’s prime long-term
objectives to develop awareness and
technology uptake in this market –
particularly for high-volume flexible
packaging print, one of the most dynamic
sectors in packaging and retailing globally.
In the past decade, the need to educate
users in the technology became even
more pressing for a more specific reason –
the discovery of ITX in baby foods in
2005. This and more recent incidents of
photoinitiator migration through food
packaging have been the prime drivers for
a continuing programme of locallanguage food packaging seminars for
printers and end users organised by our
association across Europe. The seminars
in Germany, The Netherlands, France and
Italy encompassed all aspects of UV and
EB for food packaging, including
chemistry, equipment, case studies, and
views from converters and brand owners.
Food safety remains a key concern for our
members – and indeed for the entire
packaging value chain. While it is unclear
when we can expect harmonised EU
regulation, dialogue and exchange of
information between stakeholders has
intensified over the years. We will continue
our efforts in this domain, working with
other partners in the value chain to avoid
crises similar to those in the 2000s.
In a broader context, the Uvitech project –
funded by the European Commission’s
Growth Programme – delivered an
extensive risk assessment for SMEs (the
major users in the packaging print industry
of radiation curing), based on high-quality
measurements, of inkfly produced during
UV printing. The results are essential
reading for any company involved in, or
intending to change its printing process to
include UV curing, who can also benefit
from our clear product safety datasheet,
widely circulated within the packaging
print industry alongside specific suppliers’
literature.
Other major research into the effects of UV
curing on printed products was conducted
by the German graphical technology
research association Fogra on behalf of our
association and INGEDE, the international
association of the de-inking industry.
Sponsored by a number of RadTech Europe
member companies, it answered a rising
bank of questions about the suitability of
UV-inks on paper substrates for cradle-to-
7
cradle paper recycling. The 2009 report’s
findings showed that it is possible to
produce UV printed products that do
indeed deliver good de-inkability by
adjusting the formulation of the UV
printing ink: the choice of acrylates
(oligomers) significantly affected de-inking
results, while the type of photoinitiator was
found to have less influence.
In this important marketplace today,
conventional UV curing with lamps is the
industry standard on high-speed roll-toroll presses. However, we are seeing that
major printing press manufacturers, both
analogue and digital, are now not only
exploring but installing LED UV curing
units on their machines -- because of the
handling/health and safety advantages. In
fact, a roll-to-roll inkjet label press which
is fully UV LED cured has recently been
announced. It is also now proving
possible to combine UV LED with
conventional high-performance UV
curing lamps to achieve a simpler,
quicker, on-press coating, or to install a
system where standard UV lamps can be
easily replaced by UV LED units as prices
for this new technology come down.
and releases neither odour in the cured
inks nor VOCs or other air pollutants. An
early adopter of EB curing was a leading
innovator in packaging materials -- Tetra
Pak – who, in 1982, decided to use weboffset printing with EB curing of the inks,
and equipped most of its printing plants
worldwide with this combination.
It is worth noting that UV and EB curable
inks are now also assisting in the glass
packaging market, particularly for bottled
beers, providing direct-to-substrate print
and eliminating the need for separate labels.
One factor that has slowed the wholesale
adoption of UV LED technologies in the
field of packaging print is the high initial
set-up costs – a situation mirrored by EB
curing – but costs are reducing as uptake
increases, and our association has not
stood still in promoting the value of
radiation curing technology to converters
and end users.
RadTech Europe organised a seminar in
2012 in The Netherlands, held in German,
recognising the needs of strategic decision
makers in assessing the benefits of modern
EB technology in both the coating and
printing technologies with the help of
industry experts. It offered participants the
opportunity to visit an operational
production plant, and to talk to the people
who designed, financed, built, operated,
and maintained an industrial EB plant.
Such industry- and substrate-specific
seminars have proved important to our
association over the years in establishing
our technologies in key application areas.
A good example is metal coatings. A
successful 2008 Metal Seminar and
Academy in The Netherlands was
followed by a second event in 2011 in
Belgium, led by the association’s metal
coatings working group, and featuring a
number of end-use case studies from, for
example, Crown Cork, Thyssen Krupp,
Daimler, Venjakob and OCAS. These
demonstrated to the 85 participants that
UV and EB metal coating not only sound
good in theory, but that companies are
already developing various successful
applications using the technology.
As our industry expands, and increasingly
works with sister organisations around the
world, knowledge and experience grow
apace, opening new doors, new
opportunities, and new challenges. Our
2013 conference and exhibition represents
another important stepping stone in its
development. As our President, David
Helsby, says, it is ‘the place to meet, find
great ideas, new products, new partners,
and new customers in a highly-focussed
environment.’

EB curing also has a place in the print
market. It offers an even smaller potential
risk for printing food packaging: it
requires no presence of photoinitiators,

somewhere
Original Radcure formulations are
designed to meet challenges, for
example, a novel application, a different
substrate, a new initiator, a particular
UV source. Commercial formulations
gradually evolve through many iterations,
bringing to bear the knowledge, skill and
hard work of the formulator.
Sometimes formulators will be asked
to develop a product that is not novel,
but it lies outside their present expertise.
It may be that a working product is
already on the market; so one begins
knowing that it is possible to replicate
it - but where to go from there! Perhaps
a sample can be obtained; however,
reverse engineering of a mixture of
curable components is a daunting task.
In any event, the objective is for a unique
formulation, having at least equivalent,
and preferably better, properties to
those of its competitor.
To circumvent tedious hours of
preliminary laboratory work, a startingpoint formulation might be sought.
Are starting point formulations useful?
By definition, such a formulation is not
what will be needed for the technically
successful product, but it can speed up
the development phase.
Where can starting point recipes
be found? Formulations listed on the
web, in books, or in trade literature are
possibilities, but frequently these are of
limited help. Will practicing formulators
really publish explicit details of their hard
won secrets? Phrases of the kind, ‘use
22% of an low viscosity UA resin’, ‘add ca.
1% of a type II photoinitiator’; or ‘requiring
1-2% of a suitable wetting agent’, are all
too familiar. The academic literature can
also be of assistance, although research
formulations are typically simplistic
and often use ingredients that are not
available commercially. Patents can offer
relevant ‘example’ formulations, which
Contents

are not available for replication. These
may, however, provide an indication of
the materials one could consider in a
starting point formulation.
Acquiring a network of personal
contacts, attending courses and
conferences and participating in
collaborative research projects is a
very effective means for gaining knowhow for starting-point formulations.
Developing a close working relationship
with raw material and equipments
suppliers can also be a fruitful source of
knowledge for initial recipes. Naturally
each supplier will want to promote their
own materials and there will inevitably
be some need for discretion, with
commercial confidentiality restricting
the scope for totally open disclosures.
For many of these approaches,
membership
of
the
Radtech
Organisations is beneficial. The radcure
industry is an integrated community of
raw material suppliers, manufacturers
of UV sources, converters and, of
course, academic researchers. From its
conception, radiation curing has thrived
on it’s openness to discussion, sharing
problems and to collaborative work.
To drive the industry forward, new
players must be drawn to Radcure
technology,
bringing
healthy
competition and opening up new
niche applications with the potential for
growth. Existing players too need to be
encouraged to expand their business
by exploiting novel opportunities.
These actions will sometimes require
formulators to venture into hitherto
unfamiliar territories. My plea is that they
are assisted through knowledge shared
as openly as possible, and that, within
the limits of commercial sensitivity,
realistic starting-point formulations are
made as readily available as possible.

Merck’s Xirallic effect pigments
regain market share in 2012
The Performance Materials division of
German chemicals and pharmaceutical
firm Merck generated record sales of €1.67
billion in 2012, up 14% over 2011, helped by
a stronger US dollar. Organically, the division
grew by 7.4% as robust growth trends in the
flat panel display industry stimulated strong
demand for liquid crystal materials, which
contribute more than 70% to divisional sales.
The Pigments & Cosmetics part of the
division also increased sales in 2012, albeit in
comparison with a moderate previous year.
Organic sales growth was seen in functional
materials for plastic and printing applications
and especially with Merck’s Xirallic family of
effect pigments, which are primarily used in
automotive coatings, the company says.
Merck has reversed a decline in volumes of
Xirallic pigments in 2011 which suffered from
supply bottlenecks due to the temporary
shut-down of the business unit’s site in
Onahama, Japan, following the earthquake
there. Last year, a second production site
for Xirallic pigments was commissioned in
Germany and this has helped to regain lost
market share.
In 2012, gross profit at the Performance
Materials division rose 9.6% to €959
million, compared to €875 million in 2011.
However, EBIT-earnings declined 13.4% to
€599 million. Profit margin declined due
to increased production costs as a result
of under-utilisation of production capacity
despite higher volumes at a time of reducing
inventory levels.
Regionally, sales in emerging markets,
which account for 73% of divisional sales,
grew 22% to €1.22 billion largely as a result of
strong demand from the emerging Chinese
display industry. In Europe and North
America, Performance Materials sales are
almost exclusively with products from the
Pigments & Cosmetics business unit. Sales
in Europe declined nearly 4% to €160 million
due to both slowing automotive production
and softer cosmetics sales. In contrast, North
American sales grew by nearly 21% to €89.5
million, driven primarily by sales of Xirallic
pigments for automotive coatings as well
as strong demand for the division’s active
ingredients for cosmetics.

US and China help to hold up
sales at Altana in 2012
Despite stagnating volume in 2012, sales
were up 5% at Altana, influenced by the
acquisition of the European waterbased flexo
and gravure inks company Colorchemie
Group in mid-2011 and positive currency
exchange rates. Earnings before interest and
taxes also improved 5% to €227 million at the
German speciality chemicals group as sales
reached €1.7 billion.
Adjusted for acquisition and exchange
rate effects, sales declined 2% in Europe
compared to the previous year. In Asia, sales
improved significantly in the second half of
the year. Overall growth was steady in North
and South America.
The Additives & Instruments division saw
a 6% rise in sales to €618 million as demand
for coatings additives and products for the
plastics industry and industrial applications
increased during the year. Additives for
industrial applications and measuring &
testing instrument sales grew strongly,
driven by the US and China, while sales to
European customers fell.
The ECKART Effect Pigments division saw
sales decline 2% to €340 million due to
general market slowdown, lower volume
and an ongoing shift in interest from silver
effects to white, black and colour hues.
Altana also noted a fashion trend away
from the use of metallic effects. Demand
in the automotive sector and industrial
coatings were particularly affected. In the
use of effect pigments on print products in
the graphics industry, there is an ongoing
tendency towards products with lower
refinement, said Altana.

Bayer MaterialScience under

Earnings at Bayer MaterialScience fell
nearly 65% in the first three months of the

the effects of a maintenance shutdown in
North America. Earnings before interest and
tax (before special items) declined from €121
million in the first quarter of 2012 to €43
RADnews supplement to RadTech News
million this time.
Sales at the coatings, adhesives and
specialties business unit declined 3.1% yearon-year due to lower volumes in all product
groups. Selling prices within the business
unit were flat compared to last year.
Across the MaterialScience division, sales
matched the prior-year period at €2.77
billion as an increase in selling prices for
high-tech materials compensated for a drop
in volumes in Europe and North America.
The polyurethane foam raw materials
business achieved higher prices and
improved first quarter sales. However, overall
volumes declined: increases in Asia Pacific
and regions of Latin America, Africa and
the Middle East were unable to make up for
lower sales in Europe and the impact of a
maintenance shutdown in North America.
Sales of polycarbonates declined in nearly
all regions.
Bayer chief executive Marijn Dekkers
contrasted the cost pressure faced by the
MaterialScience division with improving
performances at Bayer’s HealthCare and
Crop Sciences divisions. EBIT-earnings for
the Bayer Group rose 8.6% in the quarter to
€1.77 billion on sales up 2% at €10.27 billion.

Sales at the performance coatings segment
slipped 2% compared to a year ago to $1.12
billion as volumes declined 5%. Nevertheless,
lower costs as a result of restructuring meant
segment income actually climbed by 7.5%
to $172 million. Demand was described as
“solid” in aerospace and US architectural
coatings sales grew. Offsetting these gains
were a weakening marine new-build market

Toyo acquires Belgian UV-cured
inks maker
Toyo Ink has signed an agreement to
acquire all outstanding shares of Belgian
UV-cured inks manufacturer Arets
International.
Located in Niel, Antwerp, Arets had sales
last year of approximately €49 million and
has established a sales network that extends
beyond western countries. Inclusion of Arets,
which becomes a subsidiary of Toyo, helps
propel the Japanese firm in its ambition to
become the number one brand and number
one global manufacturer in this sector. Toyo
expects to capitalise on “profound” synergies
between the two companies as well as enter
new sectors.
Toyo says it plans to expand the aggregate
annual scale of its UV-cured inks product
group from the present ¥15 billion to ¥30
billion within three years.
At present, UV-cured inks are still niche
products in terms of scale. However, they
are likely to lead the development of printing
in the future. The Toyo Ink Group believes
it needs to be able to promptly provide
UV-cured inks to the market as required.

DIC reports 10% rise in fiscal
earnings through rationalisations
and price rises
Japanese inks and materials manufacturer
DIC Corporation reported a 10% rise in
operating income for its fiscal year ended 31
March 2013, helped by price revisions and
rationalisation measures which countered
lower sales. Income rose to Yen 38.5 billion
compared to Yen 35 billion the previous
fiscal year. Sales over the period declined
4% to Yen 703.8 billion due mainly to falling
shipments in Japan and the appreciation of
the yen particularly against the euro.
DIC said economic conditions from the
second quarter onwards last year became
harsher after a positive start to the year.
Demand dipped, particularly in the electrical
and electronics industries, and the company
was affected by inventory level adjustments.
In Japan, sales of printing inks and supplies
declined 3% over the fiscal year to Yen 87.7
billion. Despite this, operating income
jumped 41% to Yen 5.8 billion thanks to
price adjustments and the rationalisation of
product lines. Sales of gravure inks were on
a par with the previous year, while sales of
offset inks declined owing to the existing
downward trend and a loss of commercial
rights for certain products. News inks sales
remained level, bolstered by robust sales
of colour inks which countered a general
decline.
DIC’s sales of inks to the Americas and
Europe declined 4% in the year to Yen 218.6
billion and operating income declined nearly
7% to Yen 4 billion. Sales of packaging inks
were steady, while publishing ink sales
continued their downward trend.
In China, Southeast Asia, India and the
broad Oceania region, overall inks sales
were virtually unchanged from the previous
fiscal year at Yen 60 billion, including sales
from the acquired New Zealand Pacific Inks
business. However, operating income rose
almost 10% to Yen 5.2 billion. Sales were
“robust” in India, but somewhat depressed
in China due to flagging economic growth
there. In Southeast Asia, sales of gravure inks
were “healthy”.

New cleavable photoinitiator
architecture with huge molar
extinction coefficients for
polymerization in the
340-450nm range
The development of new photoinitiator
systems over the last 50 years has focused
either on new photoinitiating structures or
the modification of known structures. The
former approach has proven challenging, but
recent achievements include photoinitiating
systems containing C–Ge, Si–Si or C–Si bonds,
and the N-heterocyclic carbene (NHC)
complexes of boranes. The latter approach
has been more prolific in providing new
photoinitiators with different absorption
characteristics.
This paper describes the synthesis
and the curing characteristics of a type
I trifunctional photoinitiator (Tr-DMPA),
prepared by grafting three 2,2-dimethoxy2-phenylacetophenone (DMPA) units onto a
truxene scaffold. that absorbs in the near-UV
region (suitable for LEDs, halogen lamps or
laser diodes), has a high ε coefficient and an
efficient photocleavage process.
The value of the Tr-DMPA photoinitiator
was demonstrated by the photoinitiation of
a free radical polymerisation of TMPTA (using
a Hg-Xe lamp) and a cationic polymerisation
of an epoxy resin, an epoxysiloxane and
a divinyl ether in combination with a
diaryliodonium salt (using a 405nm laser
diode). The attachment of the DMPA units
onto the truxene scaffold increases the ε
coefficient from about 400 M-1 cm-1 (at about
332nm) to 63 000 M-1 cm-1 (at about 338nm),
one of the highest extinction coefficients
Photo-crosslinking of polymeric
photobase generator bearing
O-acyloxime moieties with low
eliminating by-products and high
sensitivity
Photobase generators release an active
base upon irradiation, which can act as a
crosslinker for epoxy resins. O-acyloximes
are one class of photobase generator that
produce an amine (from irradiation followed
by hydrolysis) and a ketone by-product. This
ketone by-product can often migrate within
the matrix, leading to a loss of film thickness,
or exude to the surface and possibly cause a
problem in packaging and food applications.
of a new O-acyl oxime monomeric
photobase generator, 4-vinylacetophenone
O-phenylacetyloxime (PaVO), and its
copolymer with glycidyl methacrylate. It
was proposed that the copolymer would
not release a ketone by-product. The curing
behaviour of the copolymer was studied and
compared with a formulation comprising
poly(glycidyl methacrylate) and the low
molecular weight photobase acetophenone
O-phenylacetyloxime (PaApO).
The photoreactivity and thermal stability
of the two systems was similar. It was shown
that the irradiated PaApO/PGMA system
produced free acetophenone, which was
lost from the film (according to the authors
probably during irradiation), confirmed by
spectral and film thickness changes. No such
loss was observed for the PaVO-co-GMA
copolymer. After irradiation, the films were
heated at 140°C and then soaked in THF for
10 minutes. Both films were insoluble in THF,
but the PaVO-co-GMA copolymer film had
a higher level of crosslinking. A secondary
photoreaction involving irradiation of the

sol-gel reaction
Photoinitiated cationic
polymerization of limonene
1,2-oxide and α-pinene oxide
Cationic
photopolymerisation
is
considered an inherently green process,
because it requires relatively little radiation
energy to initiate the polymerisation
process (formation of the cation); like most
photopolymerisations, there is no need
to use solvent; and it is possible to use
monomers readily prepared from renewable
resources. Crivello et al reported the use
of epoxidised vegetable oils in cationic
photopolymerisations back in the 1990s. In
this paper, the authors describe the cationic
photopolymerisation of epoxides derived
from two monoterpenes: limonene and
α-pinene.
It was shown that both limonene 1,2-oxide
and α-pinene oxide were efficiently
polymerised using diaryliodonium and
triarylsulphonium salt photoinitiators, but it
was also observed that the purity of the
monomers is important: the commercially
available epoxides were less reactive than
purified epoxides.

It is known that organic-inorganic hybrid
materials prepared via the sol-gel process
have very attractive properties including
improved toughness and thermal stability,
which may not be found in either the
organic or inorganic component alone. In
this work, hybrid materials were prepared
using a polyurethane/epoxy acrylate matrix
with tetraethoxysilane (TEOS), via the
sol-gel process, for optical fibre coatings.
High temperature performance of optical
fibres is limited by the thermal stability of
the coating. The effect of the TEOS content
on the thermal stability and microstructure
of the coatings was studied using
thermogravimetric analysis, x-ray diffraction
and the surface morphology was examined
using atomic force microscopy.
It was shown that for the ratio of
TEOS:(PUA+EA) of 0.4:1, nearly uniformly
dispersed silica nanoparticles in resin
were obtained, but at higher ratios, silica
agglomeration was observed, resulting in a
rougher surface. The ratio of TEOS:(PUA+EA)
of 0.4:1 also gave the optimal thermal
stability: the temperature at 5 wt% loss and
the initial decomposition temperature were
155°C and 110°C respectively.

alpha-pinene
oxide
limonene-1,2-oxide
α-Pinene oxide is more reactive than
limonene 1,2-oxide, because it undergoes a
simultaneous double ring opening reaction
(both the epoxide and cyclobutane rings).
However, α-pinene oxide also undergoes
more undesirable side reactions than the
limonene oxide. Consequently it is concluded
that neither epoxide will probably find use
in homopolymerisations, but they can add
value as comonomers with multifunctional
epoxides and oxetanes, being effective at
increasing reaction rates and shortening
induction periods.

Preparation of hyperbranched
polyester polyol-based urethane
acrylates and applications on UVcurable wood coatings
There has been some interest in the use
of hyperbranched polymers in UV curable
coatings. The advantages of these materials
are principally lower viscosity (due to the
branched nature of the polymer) and the
high functionality.
In this work a series of first and second
generation hyperbranched urethane
acrylates were prepared by forming first
hyperbranched polyester polyol from
dimethylolpropionic acid and one of three
core diols (2,2-bis(4-hydroxyethoxy)phenyl
propane, 2,2-bis(4-hydroxyethoxy)phenyl
hexafluoropropane and a polyester of
1,4-cycloheanedimethanol and adipic acid)
via melt condensation reaction and then
reaction of the polyol with an isophorone
diisocyanate-hydroxyethyl methacrylate
adduct.
The coating formulations (containing the
HB urethane acrylate, N-vinylpyrrolidone,
hexanediol diacrylate, TPGDA and Irgacure
184) were prepared and applied to Teflon
plates (for free films) and wood substrates
and irradiated.
It was found that, in general, coatings
containing the second generation
hyperbranched urethane acrylates displayed
better film properties, attributed to the
higher functionality and level of crosslinking.
Of these HB urethane acrylates, the
1,4-cyclohexanedimethanol-based oligomer
gave the coating with the highest free
volume and a lower level of crosslink density,
resulting in diminished mechanical and
physical properties. All coatings displayed
high gloss and good adhesion to wood.

and characterisation of two urethane

were characterised by 1H & 13C NMR, FTIR
spectroscopy, GPC, electrospray ionisation
mass spectrometry and thermogravimetric
measurements.
Photo-DSC was used to study the
photopolymerisation of the urethane
dimethacrylate. It was shown that the degree
of conversion of the methacrylate groups
depended on the choice of monomer and
photoinitiators, temperature and viscosity.
Photopolymerisation shrinkage of a mixture
of cinnamate monomer (20 wt%), diglycidyl
methacrylate of bisphenol A (bis-GMA),

Divinylarene dioxide resin
compositions
US 2011 0319515, June 2011,
Dow Global Technologies, USA
The use of certain styrene monomers as
the epoxy component in cationic curing is
known to demonstrate poor stability with
respect to hydrolysis. Such compounds are
used in adhesive and coatings formulations
but can also suffer from low cure speed and
poor odour.
A suitable resin is described as a divinyl
arene dioxide , such as divinyl benzene
dioxide (DVBDO). The conventional epoxy
materials in use also suffer from limited cure
speed due to the nature of the epoxy
functionality. The DVBDO is seen to offer
considerably enhanced cure speed when
used in the manufacture of pigmented inks
or coatings and they also exhibit higher heat
and environmental resistance.
O

meta isomer
O
O
para isomer
The DVBDO can be found in the ortho,
meta or para isomers, but the ortho structure
is rarely found.
The isomers are produced in the ratio or
2:1 meta:para isomers.
The odour of the inks produced is also
seen to be lower, which may be in part to
the reduced level of photoinitiator able to be
used due to the rapid speed of cure.
Epoxy functional radiation curable
composition containing an epoxy
functional siloxane monomer
WO 2012 162376, May 2012, Bajalski et al, USA
The controlled transmission of light
is important in areas such as optical
waveguides, where the signal loss over
distances needs to be minimised. Fabrication
of the quartz and glass materials used
traditionally can be inconvenient and
often involve inefficient high temperature
processes. A solution to this problem is to
use a cured silicone composition to produce
a suitable waveguide.
In the compositions given, an epoxyfunctional
organopolysiloxane
resin
(A) is used with an epoxy-functional
organosiloxane oligomer (B), a cationic
photoinitiator (C) and, in some cases, (D) an
organic solvent.
The composition is applied to the surface
of the substrate, exposing at least some of the
composition to radiation with a wavelength
of 150 to 800 nm. This exposure produces
a partly cured film. The unexposed regions
are removed with a solvent. The remaining,
partly cured composition is then heated
(to 110°C) to form at least one silicone core
having a refractive index of 1.45 to 1.60 for
light at 589nm. The substrate has a refractive
index less than that of the silicone core. A
second silicone composition can be used to
cover the substrate to form a clad layer.

PPG Industries Ohio Inc, USA
Radiation cured coatings are used
successfully in limited commercial
applications.
Improved
performance
characteristics, such as smoothness, flexibility,
adhesion to various substrates would make
radiation cured coatings more suitable
for applications such as in the automotive
market.
A dual cure coating is described, which
comprises
1.
A melamine groupcontaining polyethylenically
unsaturated compound;
2.
An acrylate-containing composition
containing a urethane or epoxy
acrylate and a multifunctional
acrylate monomer, which is present
at a level sufficient to provide a
cured coating with a glass transition
temperature (Tg) of 100°C or
below, and a crosslink density
of 20.0 millimoles/cc or below.
3.

Radiation curable compositions
WO 2012 136593, March 2012, Cytec
Surface Specialities SA, Belgium
The use of bio-derived products
will increasingly become attractive as
petrochemical-derived materials increase
in cost. Bio-derived cyclic ether polyols
can be obtained from various crops and
present a unique chemical structure that
could fulfil the need for a source of safer
and more sustainable radiation cured
resins. The non-aromatic structure of these
derivatives provides a high tensile modulus
and high glass transition temperature. For
instance, isosorbide di(meth)acrylates show
unexpectedly high cure speeds combined
with low viscosities and acceptable inks and
coatings properties. There is a particular need
for renewable compounds of oligomeric or
polymeric nature that can replace bisphenol
A.
A radiation curable composition has
been produced that comprises at least one
acrylated compound (A) and at least one
inert polyester (B) that is prepared from a
polyol component (i) comprising at least
one cyclic ether polyol and from a polyacid
component (ii).
The inert resin (B) offers exceptional
properties such as permitting fast curing,
good solubility, low viscosity, low yellowing
and enhanced adhesion. The use of these
renewable materials also allows replacement
of chlorinated resins which are often used to
enhance adhesion.
Radiation curable coating

polytrimethylene ether glycol
WO 2012 064433, October 2011, E.I.
Du Pont de Nemours, USA
A low VOC radiation curable coating
composition is described for use as an
anti-microbial coating and is derived from
renewable resources.
The radiation curable coating comprises
a film forming monomer or oligomer and a
polytrimethylene ether glycol. The glycol has
average molecular weight of 100-490.
A precursor, 1,3-propanediol (PDO), can
be sourced from the fermentation of
renewable feedstocks. The polytrimethylene
ether glycol can be prepared by an acid
catalysed polycondensation of the PDO,
Patent Search
which is preferred over the ring opening
reaction of a cyclic ether, or oxetane. The
PDO route is less hazardous, stable and
lower in cost. Feedstocks, such as corn, can
be used and gives a high rate of conversion
to the 1,3-propanediol. Conventional
photoinitiators are used in the composition
and the coating can be heated or UV cured.
Such coatings were evaluated for microbial
activity in the Time-Kill test according to
ASTM E2315 and gave reductions in microbial
activity of over 99%.
Processes
Curable sublimation ink
US 2012 0038723, August 2010,
Xerox Corporation, Canada
A sublimation dye process generally
consists of two steps. The first step is to apply
the ink or toner containing a sublimation
dye to a transfer sheet in the desired image.
The second is to apply heat and transfer the
image to the permanent substrate. However,
this process has drawbacks in that organic
solvents are often used and the sublimation
toner can offset onto the permanent
substrate or require excessive heating.
A solution to these limitations is described
as the application of a UV curable sublimation
ink that comprises at least one curable
component and one sublimation colourant,
in the desired pattern. This is then cured
whilst keeping the temperature below the
sublimation temperature of the colourant.
The image is then brought into contact
with the final substrate and the temperature
increased to cause sublimation and form
a permanent image. The inclusion of
compounds that exhibit gel-like behaviour
is also described. The UV cured prints are
found to be scratch and smudge resistant
prior to the final sublimation process.
Compositions and methods for
UV-curable cosmetic nail coatings
WO 2012 121704, March 2011,
Creative Nail Design Inc, USA
UV curable nail coatings have found
popularity and are required to have
enhanced adhesion, durability, but also need
to be as easy to remove as conventional nail
polishes.
The solution to this problem is a removable
nail coating that comprises a 3-dimensional
(3D) thermoset lattice inter-dispersed within
a network comprising a solvent-soluble resin.
The composition is preferably a semi-mobile
gel, which is shaped by the technician
and polymerised to form a nail structure.
The polymer that conveys enhanced
adhesiveness in the nail is also solvent
sensitive at the polymer/nail interface. A ratio
of 90 parts PMMA (polymethyl methacrylate)
to 10 parts PMAA (polymethacrylic acid)
gives the desired properties. Inclusion of
suitable pigments and photoinitiators gives
a range of acceptable nail coatings.
Conventional, removable nails, often take
90 minutes of exposure to organic solvent
and need physical abrasion to effect removal.
The described compositions give removal in
as little as 20 minutes, whilst maintaining the
required durability.

Final report of the second
REACH enforcement project
published
The second enforcement project initiated
by ECHA’s Enforcement Forum focused on
the REACH and CLP obligations of
downstream users. The project’s
operational phase was carried out from
May 2011 until March 2012. The national
enforcement authorities inspected 1 181
enterprises covering 6 900 substances,
4500 mixutres and 4500 safety data sheets
(SDSs). Of a total of 1 181 companies
inspected, 67% did not comply with one
or more provisions of these legislations.
Only 3% of companies failed to have the
SDSs on site. However, 52% of the
inspected SDSs showed deficiencies.
Despite the high rate of defective SDSs,
inspectors noticed an improvement in the
formats used and availability of SDSs in
comparison to earlier inspections. The
findings also showed that 93% of the
workers could have access to relevant
information from SDSs. However,
practice shows that the actual rate was, in
fact, lower at 79%.

Member States issue
dissenting guidance on
REACH/SVHC interpretation
In the past, the EU Commission gave its
legal interpretation, confirming that the
0,1% refers to the entire article as it is
imported or placed on the market. Five
Members states (France, Germany,
Sweden, Belgium, Austria and Denmark)
plus Norway did not agree on such
interpretation and confirmed their different
views consisting in applying the 0,1% to
individual “components” according to the
“once an article, always an article”
principle. They have now published their
own guidance document, which is not
aligned with ECHA/COM interpretation.
The document is downloadable from the
Swedish Chemical Agency website:

Food safety
European Commission
position on Mineral Oils
After the publication of the EFSA report,
which concluded that the presence of
MOHs in the food chain was a potential
human health hazard, the EC has decided
not to take any further action, as far as
legislation is concerned, before 2014.
EFSA’s provisional
conclusion on Bisphenol A
EFSA’s scientific experts have
provisionally concluded that for all
population groups diet is the major source
of exposure to bisphenol A (BPA) and
exposure is lower than previously
estimated by EFSA. BPA is a chemical
compound used in food contact materials
such as packaging as well as in other
consumer products. This is the Authority’s
first review of exposure to BPA since 2006
and the first to cover both dietary and
non-dietary sources (including thermal
paper and environmental sources such as
air and dust). As part of a two-stage
process of its full risk assessment, EFSA is
now seeking feedback on this draft
assessment of consumer exposure to BPA.
During a later phase, EFSA has now
closed a public consultation, which
focussed on its assessment of the potential
human health risks of BPA. After the
consultation, the Risk Assessment
Committee will prepare a scientific
opinion based on the received comments.
Meanwhile, the French agency for food,
environmental and occupational health
and safety ANSES, has called for revised
harmonized classification and labeling of
the substance, amending it to reproductive
toxicity category 1b. The Danish EPA will
be evaluating bisphenol-A-epichlorhydrin,
epoxy resin under the community rolling
action plan under REACH by 2015.
EU strategy on endocrine
disruptors
The European Commission (EC) is revising
the EU strategy on endocrine disrupting
chemicals and is expected to to establish
criteria for the identification of endocrine
disrupting substances to be used across
different pieces of legislation concerning
the control and risk management of
chemical substances by end of 2013. A
leaked draft proposal that recommended
use of the precautionary principle resulted
in heated debate in the industry, with
both proponents and deterrents discussing
the EU’s efforts to regulate chemicals with
endocrine disrupting effects.

Building Construction, Furniture and Fittings Today’s Best Practice in Achieving Functional
and Decorative Coatings
David Helsby, President, RadTech Europe, explores this very relevant process
Architectural fittings and infrastructure,
flooring, furniture and appliances may
seem to have little in common except
their intended final location – a
building… but they are, in fact, linked by
a process in their manufacture that is
lean, green, and cost-effective: energy
curing of adhesives, resins, and other
coatings.
Four major factors drive most industrial
business today: manufacturing efficiency
and speed; saving costs; environmental
and health and safety concerns; and
profitability. That is certainly so in the
areas of architectural construction and
interior fittings.
Finished goods and construction
components – which can often be
extremely large flat panels – must
incorporate long-term durability and
weatherability in their make-up.
Traditional routes to achieving such
functional finishes in the manufacturing
process are still widely employed – but
they are slow and not very energyefficient. It is therefore hardly surprising
that energy curing (drying or setting) of
coatings and finishes of all kinds is
increasingly the preferred technology in
this industry.
Energy curing delivers outstanding
performance in an extremely wide range
of application areas, creating durable,
elegant finishes on architectural panels,
glass, doors, wooden and laminate
furniture and flooring – even entire
industrial floors and car parks. It also
provides an anti-fingerprinting coating for
stainless steel, particularly for domestic
appliances, as well as protective, anticorrosion coatings for pipes. As our need
and desire to optimise environmental
credentials without penalising profitability
increase, manufacturers throughout the
value chain -- from raw materials to
finished furnishings and fitments -- are
increasingly looking at energy curing as a
considerable contribution to achieving
the answer.
The energy curing pathways
Energy curing’s core competence is speed
and efficiency. It may take one of two
paths – using UV (ultraviolet) light or an
electron beam (EB), and its definition of a
‘coating’ is broad. As well as providing a
glossy, scratch and slip-resistant finish for
wooden flooring panels or for painted
surfaces, it also involves drying inks – fast
-- on a printing substrate, and sealing a
photovoltaic solar panels produced using
the inkjet process is another growing
market for energy curing.
Flooring
It is essential that the surface of a parquet,
vinyl or marble floor is properly sealed to
deliver a scratch and stain-resistant antislip finish which, indeed, may need to be
repaired and restored as its working life
moves on, or as accidents happen. An
energy-cured coating can deliver this,
throughout the floor’s life, using offline
UV equipment, which may even be handheld. Large offline UV units are also
responsible for creating entire floors in
new factory buildings and car parks.
Doors and furniture
haptic varnish coating to the cover of a
smartphone.
UV curing, using photoinitiators (and
latterly LED technology), is the choice for
flat surfaces, and EB -- with higher initial
investment and running costs -- for highvolume, three-dimensional, and heatsensitive projects. Both pathways are
energy-efficient, and EB in particular
offers reduced CO2 emissions. They can
also actually enhance and optimise the
performance and quality of the coatings
they cure while dramatically reducing the
lengthy drying times and heat/energy
requirements of traditional curing
methods.
Buildings, inside and out
Both end users – professional and amateur
builders – and component manufacturers
themselves can benefit from energy-cured
finishes on the products they employ,
especially where product performance is
critical. In building and construction,
there is increasing use of plastics as
structural components – particularly for
roofing panels and windows. Such large,
flat surfaces are ideally suited to UV
curing, which instantly and costeffectively delivers abrasion, scratch, and
weather-resistance and enables the
manufacturer to move the panels
immediately out of the factory and into
packaging and storage.
Glass
UV curing can also add thick laminate
under-layers to glass panels to create
shatter-resistant safety glass, protecting
both people and property. Curing
Decorative and protective finishes on
items of furniture for the home, and for
doors, are two more long-established and
popular applications for energy curing.
This is a market which continues to find
new and creative ways of adding value for
its consumer customers.
A single knowledge source
Whatever the requirement in the context
of architectural and furnishing
components, the expert international
supply chain that has built up since the
energy curing technology made its first
appearance 40 years ago will create the
perfect chemical formulation for any
given application, and any desired surface
finish. UV and EB curing will deliver
energy savings over traditional drying
methods; an instant cure, saving valuable
time; improved environmental credentials
and reduced greenhouse gases; and a key,
proven element in modern best practice
manufacturing that is still opening up new
markets. RadTech Europe, the association
promoting the technology, represents the
major companies across the EB and UV
value chain.

New Study Shows Mega
Sustainability Advantages of
UV/EB Technology
Rapid Manufacturing Process Offers
Operational Benefits
A new study by FocalPoint Consulting LLC
finds that ultraviolet and electron beam
(UV/EB) technologies have the potential to
reduce energy demand and greenhouse
gas releases by up to 90 percent, an
added benefit to well documented
significant reductions in volatile organic
compound (VOC) and hazardous air
pollutant (HAP) emissions.
UV/EB is widely recognized as a pollution
prevention technology with wide
application across manufacturing industries,
including printing and packaging;
electronics; metal, plastic, and wood parts
and products; and composites. The
FocalPoint study outlines a quantitative
method for estimating and comparing the
energy demand and emissions of thermal
and UV/EB curing in equivalent printing and
coating processes. “We are excited to see
yet another report showing UV/EB reduces
energy demand and greenhouse gases-these are issues that help make a low-energy
process into a high-energy business!,” says
Don Duncan of Wikoff Color Corporation
and President of RadTech.
According to Ronald Golden, Ph.D.,
founder and principal of FocalPoint, “Based
on RadTech data for 2011 North American
shipments of UV and EB curing
formulations, the annual benefits from the
use of UV/EB instead of thermal curing are
estimated as a savings of 60 Billion Cubic
Feet of Natural Gas; 620 Thousand MWh of
Electrical Energy; 3.75 Million Metric Tons
of CO2 Emissions; and 220 Thousand
Gallons of Diesel Fuel Consumption.” The
FocalPoint study compares the use of UV/EB
technology with traditional manufacturing
processes, showing how “UV/EB curing can
help manufacturers achieve major
quantitative reductions in energy
consumption and harmful emissions.”

and achieving the right color the first time on press.” The eXact spectrophotometer makes color measurements quick and easy for brand managers, pre-media, ink suppliers, printers and converters, while
solving the widespread problem of measuring and
matching colors on various substrates and surfaces.
Sun Chemical Supports Print
and Packaging Industries as
They Migrate to X-Rite eXact
Spectrophotometer
eXact offers customers a way to measure true daylight conditions by supporting all the M Standards
inclusive of the complete M1
Sun Chemical Corporation said today it is supporting customers in the print and packaging industries
as they migrate to using the eXact series of spectrophotometers made by X-Rite/Pantone.
Patrice Aurenty, Business Leader, Color Management
at Sun Chemical, said the eXact spectrophotometer
„is a revolutionary instrument that takes us to the
next steps for digital color communication, and we
are very happy to assist X-Rite introducing this into
the market, as well as into our own global color platform.“
The X-Rite eXact brings to the supply chain a simple-to-use device that is fully compliant with ISO
13655:2009 measurement standards, which printers use to match proof to press across many substrates. With split-second measurement times and
improved accuracy to simplify workflow, the eXact
instrument is the first spectrophotometer in the industry to offer customers a way to measure true
daylight conditions by supporting all the M
Standards inclusive of the complete M1.
Aurenty said most of Sun Chemical‘s print and
packaging customers currently use spectrodensitometers in their workflows, and once they have
decided to invest in the technology Sun will help
make this migration a seamless process. The eXact
instrument generates data that integrates seamlessly with the PantoneLIVE™ cloud-based color service to give brand owners a means to connect
their whole supply chains.
In addition to using advanced measurement technology, the new platform is easy to learn, thanks to the intuitive software and touch screen controls. The eXact
instruments can be set up to position key elements in

BYK Additives & Instruments
receives Platinum status from
the U.S. Green Building Council
Sun Chemical is the preferred ink supplier of
X-Rite/Pantone‘s PantoneLIVE ecosystem for the
packaging market, sharing digital targets of spot
colors efficiently within the Sun Chemical global
network.
The most recent laboratory wing of BYK Additives &
Instruments, a division of ALTANA AG, has been the
first lab building in Germany to receive the highest
distinction that the U.S. Green Building Council
awards as part of the Leadership in Energy and
Environmental Design (LEED) program.
“When packaging developers and printers mismatch a brand’s spot color, the error may appear at
the proofing or printing stage—leading to multiple
proofs and adjustments before the customer approves the job,” Aurenty said. “Such mistakes are
not only expensive, but they frequently lead to delays in product release and order fulfillment,
mounting up losses in sales. PantoneLIVE solves
this costly problem by dramatically speeding up
LEED defines a series of standards for environmentally friendly, resource-efficient and sustainable construction. Hence special importance was placed at
the planning stage on an efficient use of energy. BYK
Additives & Instruments invested in geothermal energy, heat pumps and heat recovery systems in order
to reduce primary energy consumption by over
30%. 8,000 square meters of laboratory space were
created using building materials that either come
from renewable materials or can be easily recycled.
Even the ventilation system for the 130 state-of-theart work stations meets the strict energy standards.
Dr. Gerald Kirchner, the project manager,
states: “Thanks also to the early enlistment of
the LEED certification auditor from Jones Lang
LaSalle, the project team was professionally and effectively supported throughout the entire planning
and implementation process.”

UV technology for newspaper
printing
IST METZ presents energy-efficient UV systems at
World Publishing Expo
With the BLK®-6, IST METZ GmbH will be showing the latest product development for newspaper
printing at World Publishing Expo, which will take
place from 7–9 October in Berlin. Together with
technotrans AG, the UV specialist presents innovative products and solutions at booth 1.2.450.
The BLK®-6 is a newly developed UV drying system designed for web-fed printing. When compared to conventional UV systems, remarkable
progress has been made in drying performance of
the BLK®-6 without having to increase the UV
lamp output. This means greater productivity with
reduced operating costs.
The intelligent IPS control system governs all functions and components of the UV system. BLK®-6
UV systems are equipped, as a standard, with a
UV online sensor. This has made it possible for the
first time to measure the UV radiated power of a
UV system online. Compared to conventional UV
systems, the process reliability has been increased
considerably with this new feature.
The BLK®-6 boasts of extremely high efficiency.
Instead of the previous three BLK®-2 type units
with 200 W/cm, the same excellent drying results
can now be achieved with just two of our new
BLK®-6 units with 180 W/cm. Operating costs
have been considerably reduced thanks to the significant reduction in energy consumption.
In comparison to thermal drying, UV technology
offers economical and technical advantages for
newspaper printing, especially in the area of small
and mid-sized print runs: Through the low heat input on the paper web there’s no corrugation in UV
printing, as well as no fan-out effects. The instantaneous curing of inks prevents the set-off of ink on
idle rollers, folders, transportation belts and mailroom equipment. UV systems are compact in size
and are associated with significantly lower investment costs than heatset dryers.
Labelexpo Europe 2013: The
one-stop-shop for UV and LED

At Labelexpo Europe, the world’s most important
trade fair for label printing, which is taking place
from 24-27 September in Brussels, UV systems
manufacturer IST METZ will be showing the latest
trends in UV label printing at stand 5D45.
Both standard and LED UV technology will be presented at Labelexpo Europe by IST METZ. The intensive cooperation with the British LED UV spe-
cialist Integration Technology Ltd. (ITL) which was
established in 2011 allows for the offering of UV
technology for all purposes from the one source.
With each product range complementing the other,
the customer is set to benefit from the collaboration
which today sees an even wider spectrum of UV solutions available.
The UV systems from both manufacturers will be
demonstrated live at Labelexpo Europe, amongst
them the latest generation of ITL’s water-cooled LED
UV system Solidcure 2, installed on a flexo press.
Furthermore, IST METZ will show the new aircooled product generation MBS®-6 which represents the progress made in the sustained improvement of economic energy use, a theme which has
long topped the list of development goals for IST
METZ GmbH. With MBS®-6, IST METZ is taking the
next successful step towards improving the energy
balance of UV label printing. The efficient and innovative UV system will be installed on various label
presses of renowned printing press manufacturers at
the trade fair.
Another trending topic at the trade fair presence of
IST METZ will be a new concept that makes it easier
for label printers to switch to LED UV technology.
Milestone in UV technology
IST METZ hands over ten thousandth electronic
power supply unit to Edelmann
On occasion of the ten thousandth electronic power supply unit for UV systems manufactured by IST
METZ GmbH, the company presented Carl
Edelmann GmbH with an award on 31st July.
Electronic power supply units belong to the peripheral equipment of a UV system. Since 1998, these
devices have been manufactured at eta plus electronic GmbH, a subsidiary of IST METZ GmbH. The
ELC® range of electronic power supply units have
been developed specifically to operate UV lamps.
They optimise production safety in the print room
and also reduce operating costs.
The ELC® units are highly efficient with low energy
consumption. They reduce any electrical peaks
which improves production quality. The electronic
power supply unit also extends the range of adjustment of the UV lamp as the optimal lamp output
can be adjusted steplessly between 30 and 100%
depending on the production speed. The compact
design of the ELC® units means that the space required is reduced by up to 50%.
15 years after the first device had been produced,
the ten thousandth electronic power supply unit
ELC® was symbolically handed over to Carl
Edelmann GmbH. It already has been installed into a printing press at the company’s headquarter in
Heidenheim, Germany. Carl Edelmann GmbH is a
leading provider of high-class innovative packaging solutions. In twelve production sites worldwide
the familiy enterprise founded in 1913 develops
and produces folding cartons, packaging inserts
and system solutions, primarily for the health- and
beautycare markets. For many years now,
Edelmann and IST METZ have been having a fruitful business relationship.
