High gloss still has the appeal of promising a special value, suggesting an extraordinary amount of

it requires extensive care to maintain it. High gloss
is also a symbol of beauty and highly fashionable

High gloss furniture surfaces
Innovative materials make high gloss easy!
High gloss has been a continuing trend for a long time, always appearing as specific design style in
furnishings catalogues. The furniture industry formerly considered the creation of high-gloss surfaces to be labour-intensive, prone to defects and in consequence expensive to produce. Price lists
of furniture companies listed high-gloss items as high-end products. Nowadays, the manufacture
of high gloss surfaces has clearly become easier
and a wider customer segment has access to
these products.
In an interview, Michael Blasius, Manager Industrial Division Wood and Furniture responsible for
product management and application technology for PUR hot melt adhesives, told us how adhesive innovations have made significant contributions to this progress.
Mr Blasius, high-gloss surfaces have become
standard components in furniture product
ranges. They have continued to maintain their
position in the industry. How do you explain this
success?
Michael Blasius: Innovative materials have clearly
facilitated the manufacture of high-gloss surfaces.
Where the creation of a high degree of gloss used
to require extensive operations with several applications of lacquer, the processor can now rely on
high-gloss decor sheet material and also on high
gloss foils. This means high gloss from stacked
material or reels, allowing a reliable application
onto the furniture panels.
How did these new innovative application solutions come about?
Michael Blasius: This requires a team effort. “High
gloss” is a good example of successful co-operation
between material manufacturers resulting in an in-
novation which is now enjoying market success.
The customer is profiting here when the partners in
the market coordinate their development activities.
Manufacturers of panels and décor foils like Niemann
Moebelteile have come up with innovative ideas, for
which we have developed the matching adhesives.
Furniture manufacturers have also gained from
this boost in innovation, since a new market has
been created. The result – the end customer gets a
high-gloss and robust piece of furniture. The muchcraved high-gloss kitchen is a good example – it
is no longer sole privilege of high-end buyers. These
products have good high gloss qualities these days,
and are available at affordable prices.
Progress P|7
Industry Wood & Furniture
Effective material combination – a variety
of high-gloss decors
“Hot melt adhesives! That’s not so easy!” – a common opinion for this process. Why should I get involved in processing hot melts?
Michael Blasius: The demands on surface finishing
processes have become higher, and not only due to the
trend towards high gloss. In general the expectations
for processing a wide variety of materials and meeting
high quality levels have grown. We must respond to
this with adhesives that do not restrict our customers.
To keep costs in check, one adhesive should be suitable for all applications, all materials, all end consumer
expectations in functionality and design. This is something only PUR hot melt adhesives can provide.
What has given Jowat the edge to facilitate the development of the right adhesive in the context of this
innovation?
Michael Blasius: Jowat values know-how that extends
beyond one industry alone. We clearly benefit from the
experience gained in a wide range of industries. At the
time we received this request from our customer Niemann, we had already gathered experience in laminating gloss sheets on print substrates and on metal. This
know-how could also be transferred to the furniture industry and its subsuppliers.
When new, innovative materials are used, the manufacturers have to adapt their processes accordingly. So the surfaces that used to be varnished will
now receive decor sheets or foil laminates?
Michael Blasius: That’s right; many of the processes
using varnish have now been replaced by the new laminating technology because of cost efficiency. In some
cases required manufacturing equipment may already
exist, such as the press, and some production steps are
well-known – veneering, for instance, is a familiar and
similar technology. Hot melt adhesives are used to bond
solid colour, high-gloss sheets such as Senosan® panels
to the appropriate substrates – i.e. wood-based composites or lightweight panels. This one-step process allows a variety of different finishes to be processed. The
quality of these is comparable to lacquered surfaces,
and is sometimes even superior. Companies without
the required processing technology can purchase panels with the desired finish – the choices are endless.

The gloss factor as design element
Sounds like this adhesive technology has everything – is this possible? Can you give some examples?
Michael Blasius: Let’s start with the most challenging
environment – PUR hot melt adhesives are preferably
used for kitchen and bathroom cabinets, which require
excellent resistance to water, steam, and also solvents.
In addition to these outstanding properties, the chemical crosslinking results in superior strength and high
heat resistance.
Other advantages of PUR hot melts are their low
processing temperatures and very good adhesion to
materials which are difficult to bond, or which require
sensitive treatment. A vast range of materials can
therefore be bonded with this adhesive system – textiles, ceramics, glass, metals, and all the way through
to the high-gloss plastic decorations mentioned earlier.
And what is the next trend in surfaces and in
adhesives?
Michael Blasius: We at Jowat do not set design trends,
we provide the trendsetters with adhesives which give
them the opportunity to convert their dreams into industrially producible items that meet the desires of the end
customer. In the adhesives market, however, the trend
towards using hot melt adhesives continues, as sales
figures clearly show.
And the progress continues – we rely on our R&D. Testing
and qualifying new raw materials and additives every day
is essential. This guarantees our customers more efficient
and flexible manufacturing processes in the future.

Bonding technology in vehicle interiors
Today, the interiors of cars are functional and have visual appeal. How well passengers feel and experience the interior is a major criterion on which a customer bases his or her purchase decision. When
considering the entire lifecycle of a vehicle, there is hardly any other area that comes even close to the
importance which the interior of a car has for the brand image. A large number of different materials
are used in development and manufacture. These materials have to match the brand image. Visual
appeal and feel follow the basic brand statements. This variety of materials must be matched by flexible and powerful adhesive systems which fulfil the specific requirements in all climate zones of the
earth, but also comply with other requirements like those for fogging performance and odour. The
adhesives used must additionally meet the demands of the automotive manufacturer with regard to
mass production: Optimized processes with short processing cycles are needed.
Laminating interior vehicle components –
bonding in 3D structures
When parts for vehicle interiors are laminated, like
door panelling, headliners or dashboards, each basic component is covered with decor materials. The
objective is to improve the visual appearance and
also the feel of the finished structural part. In mass
production, the laminate bonding methods mainly used are varieties of vacuum deepdrawing and
press laminating. The adhesive is applied onto the
decor material or the core substrate, in individual
cases also onto both surfaces. In the case of vacuum deepdrawing, a thermoplastic foil is warmed,
prestretched and laminated onto the substrate under vacuum.
In this process, the adhesive is activated together
with the foil or by the hot decor foil itself. Cooleddown tools also facilitate fast cooling-down of the
structural parts, so that after a few seconds in the
press, the part can be removed and the unit is ready for the next component. In laminating procedures
of highly formed 3D parts decor foils are stretched
to reach many times their original surface size, and
the adhesive may have to withstand extreme forces

which develop in the structural part while it is still
warm after removal from the press.
Bonding systems
Lamination of highly formed 3D components can for
instance be carried out with solvent-based adhesives,
2K PUR dispersions or reactive polyurethane hot melt
adhesives. The differences based on the adhesive
used will have consequences for the processes, but
they will also contain potential for improvement.
Method 1:
Solvent-based adhesives
Solvent-based contact and 2K PU adhesives offer an
excellent adhesion spectrum and easy handling. Depending on the type of adhesive, evaporation times
of at least 30 seconds are required. Even if the solvent systems used in modern products are free of
halogens and aromatics, the necessary measures for
protection in the workplace must be observed when
handling solvents. Solvent evaporation must also be
taken into account when considering the VOC balance sheet of the company. For these reasons, these
adhesives are frequently used only in prototype as-
1| 2011
sembly and in small series. Some car manufacturers
demand solvent-free adhesive systems for new car
models.
Method 2:
Dispersion-based adhesives
Due to the fact that dispersions are suitable for application by spray method also for complex 3D structures, the use of 2K PU dispersions has become established as standard in lamination. After drying, the
adhesives are activated by heat and bonded by pressure. In order to build up good adhesion, sufficient
pressure is required due to the high molecular weight
of the polymers used; this also means that very high
initial strength results can be achieved. The short
pressing time which may be as low as approx. 10 seconds, is ideal for reaching optimum productivity in
operations with complicated laminating machines.
A factor which draws more and more criticism is, however, the high consumption of energy and the long
time required for the evaporation of the water contained in the dispersion. Usually, additional drying
units are required, space and energy are needed.
Method 3:
Reactive polyurethane hot melt adhesives (PURHM)
Bonding with reactive PUR hot melts frequently leads
to the best results, because in addition to the thermoplastic solidification, the adhesive undergoes chemical crosslinking with moisture after application. This
means that during processing, the PUR hot melt in
the melt unit must be protected from exposure to moisture, to prevent a premature reaction of the adhesive
with associated problems in the application units.
Industry Automotive & Textile
Processes are ideal which permit application of the
adhesive onto a flat, plane decor surface – for instance onto a textile, a decor foil or a carpet – using
a slot nozzle or roller. Depending on the type of adhesive, the components precoated this way may immediately undergo further processing or be stacked,
rolled and held in intermediate storage for several
hours. Another advantage of the PUR HMs is the
chance to process inline without a separate drying or
evaporation cycle.
Using all the advantages of PUR technology, several
new PUR products, which were especially developed
for short production cycles, can now also be used for
extremely fast cycles in serial production (superfast

pressing times < 10 sec.); this was up to now limited
to dispersions. Provided the conditions for adhesive
application and the activation temperatures are met,
it is even possible to convert from dispersion technology to PUR.

Sophisticated and strong!
Modern adhesive systems meet the exacting demands of high
gloss foil lamination.
High gloss foil lamination is a process used where items with surface finish treatments need to
maintain their appeal as high-value products for a long time. Due to the variety of materials that
are to be bonded, the adhesive systems for gloss foil lamination must meet very stringent demands. This is a task which customers comply with by using a copolymer dispersion optimized
for the specific application.
Foil laminates must respond to great challenges to
protect the surfaces of graphic products while at the
same time improving their visible characteristics. The
large variety of materials to be laminated requires
high-performance adhesives.
All-rounder sought
The base material may be satin-finished natural papers or high-gloss double-coated papers and cartons; all these substrates need to be bonded in a re-
liable manner. If the base material is printed, which
is the case in most applications, the adhesive used
must perform well on a huge variety of printing inks,
which differ greatly in their chemical composition. In
addition, the adhesive has to ensure that different
plastic films or laminating foils, which may consist of
polypropylene, polyester, polyamide, or acetate, are
bonded durably to the base material.
The resulting bond should not delaminate during
Progress P|13
Industry Paper & Packaging
Visible quality – purity, cleanliness and stability are top priority
downline processing steps, such as grooving, folding
or embossing.
For all substrates in laminating, an adhesive is required which ensures efficient bonding while allowing
high line speeds. For Jowat customers, the solution is
provided by a special acrylate-based copolymer dispersion from the Jowacoll® range.
Optimised process properties
High gloss foil lamination is a translucent surface finish. Absence of contaminates, cleanliness, and stability have the highest priority – this also applies to the
adhesive. The product is assessed by performance in
application, foaming, film formation, and drying, and
also by the degree of cleanup required in the production process.
The Jowat all-rounder is champion in all of these disciplines and ensures that processing is optimal.
A special formulation minimizes foaming of the adhesive during application to the foil and reduces skin
formation on the adhesive in the reservoir. Application
flaws during processing, like streaking due to soiled
doctor blades – later on visible on the laminated product – are avoided. In summary machine downtimes
are minimized.
The film formation will also be homogenous even with
varying line speeds. Thanks to its optimised spreading and even wetting performance, the special dispersion adhesive from Jowat ensures excellent gloss
quality for the finished product.
The copolymer dispersion is also very efficient during
drying.
Convincing high gloss quality
P|14 Progress
The high solid content supports a short drying phase,
which allows higher line speeds with a constant grammage, while the high initial adhesion is maintained.
1| 2011
These performance characteristics enable processors to carry out inline embossing of the laminated
sheet in a station that operates with heated embossing rollers just downline of the laminator. As a result,
offline embossing, which is typically a second processing step in this industry, is unnecessary and the
cost benefit is obvious.
Performance of the adhesive in the
laminated product
Three major criteria determine the quality of the laminated end product: gloss level, compound strength
and cutting resistance.
Gloss measuring units on the market use the reflection principle and determine only the gloss level of the
lamination foil on the surface. The gloss level of the
entire compound is assessed visually, so the perception of the human eye is used to determine the degree
of gloss. In comparison to competitors‘ products, the
Jowat all-rounder achieves an excellent gloss quality,
combined with a low adhesive grammage, with the
associated benefit of cost efficiency.
Peel force measurements provide specific information on the quality of a bond. A strip of laminated paper
is cut in an exactly defined length and width, and the
foil is peeled back at a pre-set speed and a specific
angle. This is where surfaces with a high level of printing ink are usually the most critical. When the printing
inks have not dried adequately, or the surface tension
of the foil is insufficient, this may cause delamination. Jowat therefore carries out peel tests on sheets
which have received full two-colour coatings before
lamination, to simulate a “worst case” scenario. The
peel strength data determined when testing the copolymer dispersion exceeded the minimum requirement by a wide margin.
With regard to cutting resistance, Jowat developers
have been able to optimise the adhesive. It has been
modified in such a way that in three side trimming
or guillotine cuts, no adhesive was squeezed out of
the glueline. This will result in clean sheet edges, and
adhesive accumulation on the cutters is prevented.
Industry Paper & Packaging
companies and adhesives manufacturers have now
succeeded in attaining synergies, and in increasing
line speeds during lamination to a maximum of up
to 80m/min. To reduce costs, the trend is clearly heading in the direction of lower grammages, also reduced set-up and cleaning times. Quality is the No. 1
success factor in high gloss lamination – the customer goes where his demands are met, and where
the trends for unusual designs and material mixes receive the fastest and highest quality response. When
using the copolymer dispersion Jowacoll® 764.26,
specially developed for high gloss lamination, Jowat
customers opt for reliability. They are choosing a genuine all-round product which scores high in all areas.

Availability – worldwide and short-term
Making the right product available at the right time to our customers worldwide – that is our goal.
We undertake a major share of our R&D work with the objective of providing innovative and increasingly efficient adhesive products to our customers, to facilitate enhanced value creation in
their processes.
The Jowat-Toptherm product range is one such product innovation. These hot melt adhesives are formulated with raw materials which have already been very
extensively used in other industry sectors, and are now
the adhesive bases to create hot melts with exceptional characteristics and processing properties. They
are high-performance, can be delivered at short
notice, and are available around the globe.
A new polymerisation procedure employed for the synthetic manufacture of a special polyolefin has substantially broadened the choices for our formulators. With
this product range, we are offering a hot melt adhesive
system based on raw materials that are available independently of the global market. The formulations are the
result of interactive research and development among
raw material suppliers and Jowat, and are now available to us and above all to our customers, securing our
own supply capacity and the customer’s productivity.
At the last Jowat symposium, the challenges of poor

raw material availability, the unsatisfactory observance
of delivery deadlines by the raw material suppliers, and
the associated exploding raw materials costs, were widely and openly discussed with our guests. We accept
this situation as a challenge. Whenever possible, we
help our customers in maintaining continuous production by providing short term availability of supplies.
In the context of globalisation, this support is not just
required on a national scale, but also at the same time
and to the same standard in different locations worldwide because frequently product development and
manufacturing take place in different countries.

Product development on the basis
of sustainable raw materials
Taking responsibility for protecting the environment and resources for generations to come –
this is part of the corporate philosophy of Jowat
as a family enterprise.
Modern adhesives can increase efficiency in industrial production processes, saving valuable resources
for future generations. This may start out with the
formulation and the manufacture of adhesives, but is
also implemented when the adhesives are used in the
production facilities of our customers.
Saving energy in the manufacturing processes of
adhesives as well as during processing is certainly a
key factor. Additional savings on the processor side
can be generated by reducing adhesive consumption; hot melt adhesives which are more stable in the
melt may lead to increased availability of machines,
and shorter pressing times will also save energy.
Nothing, however, has been as hotly debated over the
past few years as the development of products based
on sustainable raw materials.
Adhesives containing sustainable raw materials
Developing so-called biological adhesives based on
sustainable raw materials is a topic which is debated
throughout the entire industry. The major sources for
the production of adhesives are, after all, oil-based
raw materials, but crude oil is an exhaustible source,
and also subject to substantial price fluctuations.
When considering the main components of adhesives, it becomes clear that not all raw materials
can be replaced by sustainable materials. Jowat is
focussing on partial solutions – and with great success. Natural products such as carbohydrates, cellulose, starch, and natural latex, are used for Jowat
adhesives if they are suitable, also natural resins,
like colophonium or rosin, or tall oil rosin. For years,
Jowat has been using renewable natural rosin derivatives in almost all thermoplastic hot melts. Dispersion adhesives also contain substantial percentages
of raw materials from sustainable sources.
In addition, we are involved in various fundamental
research projects sponsored by the German Federal
Ministry for Food, Agriculture and Consumer Protection – which means that every newly developed
adhesive product is carefully examined for a possible incorporation of sustainable raw materials.

due to the fact that they contain between 10 % and
50 % of natural raw materials from sustainable sources, they are free of formaldehyde and can be applied at low temperatures, which results in energy
savings.

News
Outstanding innovation!
Friedrich Brandau receives the 10th Jowat Adhesive Research Award
“Major impact factors on functions and characteristics of edgebanding on
frameless honeycomb panels” is the title of the graduating thesis for which
Friedrich Brandau received this year’s 3,000 € Jowat Adhesive Research
Award. The result of this research is convincing and proves that even on
limited surfaces, adhesive results can be achieved that provide good structural properties. The former student of the University of Applied Sciences
of Eastern Westphalia-Lippe and graduate engineer was able to convince
the judging panel above all because his thesis showed field-related research and practical relevance. This will pave the way for new design ideas
using lightweight panels in the furniture industry.
