silicone
properties
Silicone polymers are inorganic compounds with inherently
unique properties, especially thermal and chemical stability
within a wide temperature range, UV resistance, and
environmental compatibility. In the scope of solar applications,
the most important performance of silicone is its durability,
which has been proven in many other fields and is clearly
outperforming durability of organic polymers.

As a photovoltaic module has to be warranted for 20 to 25
years, durability is definitively a key requirement. Solar module
manufacturers have to ensure that power output remains
as stable as possible. Protection of solar cells and electrical
connections in order to withstand harsh environmental
conditions over the lifecycle of the solar module becomes
a basic technical requirement.
Bluestar Silicones has developed a special range of sealants
and adhesives (CAF), encapsulants and potting materials
(ESA) for solar applications, designed to provide long-term
sealing, bonding, and protection against moisture, chemically
aggressive environment, UV, thermal cycling and mechanical
stresses. Our range of solar module assembly solutions
includes high-performance frame sealing and Junction box
bonding materials, as well as cell module coatings, cell
encapsulants and Junction box potting agents.

Bluestar Silicones and Sustainable Development:
meet the needs of the present without compromising the ability of future
generations to meet their own needs.
Responsible, sustainable development has
always been a part of Bluestar’s identity.
Water recycling and filtering was the reason
behind the foundation of Bluestar in the 1980s,
and remains one of the Group’s key activities.
In this process, Bluestar Silicones is committed
to a sustainable development strategy
promoting the use of new technologies in order
to better protect nature and respect man,
for the sake of future generations.
Bluestar Silicones’ ambition is to improve
the day-to-day management of the natural
resources. At the Kyoto summit (1989)
and the Copenhagen summit (2009), reducing
greenhouse gas emissions through the use
of renewable energies such as solar, has been
a key element in the different governments’
strategies. Through the silicone products
present in various applications in the
photovoltaic processes, Bluestar Silicones
is contributing to a better use of this energy
source which is free, abundant and renewable.
This presentation of Bluestar Silicones’
products for solar applications will help to
better describe the Company’s contribution
to sustainable development.

Having signed its name to the Responsible

Silicones has committed in managing industrial
and commercial operations with a continuous
focus on improved safety, health and
environment.
Bluestar Silicones is very proud to provide
technical solutions in order to improve solar
energy systems and ensure renewable energy
to be used more intensively in a near future.
A complementary range of products for Solar
Module manufacturing has been designed
providing:
cost effectiveness
increased durability
improved performances
One of the key parts of the module is
the part where all the energy coming from
each individual solar cell is collected and
delivered on the grid through standard
cables. Junction box is the usual name of
this essential part of the solar module.
Potting of the Junction boxes
The Junction box, usually positioned on
the back-sheet of the module, is used
as an exit for the cables but could also be
an entry-point for moisture. This could
lead in worst cases to destruction of the
electrical unit. Moisture protection combined
with flame resistance, electrical insulation
and thermal conductive properties of potting
agents (Bluesil™ ESA) are key parameters
for a long term operation of Junction boxes.
Bonding & Sealing of PV frame
The adhesives (CAF) required for modules are
exposed to extreme conditions. They have
to withstand and compensate alternating
temperature fluctuations of up to 100°C
between hot and cold weather conditions, as
well as to resist to the wind, snow, moisture
and mechanical stresses.
Bonding of the Junction boxes
Moreover, the Junction box must be
connected to the back-sheet for all the life
of the module. Our adhesives (CAF) are
designed to provide long-term bonding and
protection against moisture, environmental
attack, mechanical and thermal shock.
Cell Encapsulation
For the cell encapsulation application, longterm durable transparency is required. This
is the reason why our encapsulant agents
(Bluesil™ ESA) are well suited for these needs
thanks to their excellent optical transparency
over a wide light spectrum, outstanding UV
stability, high temperature and electrical
stability and protection against corrosion.
These encapsulants contribute to improve
long term cell efficiency.
There are several categories of specific
standards for photovoltaic modules:
performance qualification of the crystalline
module : IEC 61215, ISPRA 503
performance qualification of the thin-film
module : IEC 61646, CEC 701
Safety qualification depending on the
country: TÜV safety class II in Germany, UL
1703 for North America and IEC 61730 for
international.
Our Solar products have been homologated
according these standards with different type
of photovoltaic modules. Independently of
the technological assembly type of the solar
module, we also perform ageing tests on our
materials (particularly for adhesion) like the
hot and wet test (85°C ± 2°C, 85% ± 5% HR
for 1000 hours) described in the IEC 61215 for
example.
Technical service
Our Technical Customer Service Laboratory
support our customers by developing analysis
and tests to assess performance of our
materials and contribute to an optimized
design of the parts where our materials
are used. We also offer our customers the
opportunity of producing prototype series
with our dispensing equipment or in close
cooperation with dispensing equipment
suppliers. Technical support for mass
production can be provided by our team of
technicians who have a strong experience
of managing silicone materials in a wide
range of applications like adhesive, potting,
encapsulating and sealing applications.
We also have the facilities to perform tests
in ageing conditions involving UV exposure,
moisture and thermal cycling.
Silicone Solutions
For Potting & Encapsulation
Bluestar Silicones materials are used for photovoltaic
module applications to improve their reliability and
durability due to their unique features. ESA products,
Electronic Silicone Adhesives, are two components
silicone elastomers which cure at room temperature
(RTV-2) by polyaddition reaction. The curing can be
accelerated by heating. After curing, gels or elastic
materials are available from the ESA range.
ESA Potting materials have excellent weather resistance
and give an excellent protection against moisture.
These properties associated with high electrical
insulation performances, fire resistance (UL approvals),
thermal conductivity, wide temperature range stability
(-40°C to +150°C) are key parameters for a long term
operation of the Junction box. Suitable for automated
dispensing, ESA potting agents are ideal for mass
production. A quick curing version is also available,
which allows to turn the panel around 15 minutes after
having applied the product.
ESA Encapsulation materials have an excellent optical
transmittance over a wide light spectrum. This high
transparency combined with outstanding UV stability,
high temperature and electrical stability, and protection
against moisture make ESA encapsulants excellent
candidates to improve long term cell efficiency.
In addition, ESA encapsulation agents also provide
excellent adhesion properties.

SIL 12 011 3-1 POT
Bluestar silicones offers coating specifically designed
to provide an excellent durability and thermal stability
required for solar consumer products. Outstanding
resistance to UV solar radiation, climatic and ageing
agents also ensures long term protection efficiency.
Silicone Solutions
For Sealing and Bonding
Bluestar Silicones has developed an exhaustive range
to cover all technical, economical and environmental
requirements.
CAF are room temperature vulcanizing (RTV-1) silicone
elastomers which cure at room temperature:
As soon as the product comes into contact with
atmospheric moisture.
The cure rate increases with temperature and ambient
moisture level.
Special grades of RTV-1 have been developed for the Solar
Energy market. These CAF products give excellent adhesive
properties to several back sheet materials such as PVF (PolyVinyl
Fluoride) and PET (PolyEthylene Terephthalate) and composite
with PVDF (PolyVinyliDene Fluoride) from several suppliers. This
CAF range also provides outstanding adhesion on Junction box
material’s like PPO (PolyPhenylene Oxide) or PC (PolyCarbonate).
These products maintain good elasticity over a wide temperature
range (-50 to 180°C) with excellent weatherability and electrical
insulation properties.
Thanks to the quick curing of CAF products, the drying time is
reduced to 7-8 hours as a cured thickness of 2mm is obtained
after that time at 23°C and 50% relative humidity. This time
could be reduced by using SUNSIL 2030 activated.

Durability test results
Bluestar Silicones has performed ageing test according
to IEC 61215 in order to check the bonding properties of
the CAF adhesives on PVF and also on composite PVDF /
PET composite materials for 1000 hours at 85°C with 85%
relative humidity, which is the damp heat test.
The thermal cycle test is less aggressive for the silicone
performances than the damp heat test, as it’s only a
variation in temperature from - 40°C to + 85°C. Lap shear
tests are carried out in order to measure the lap shear
strength and the cohesion failure.
Lap shear strength MPa, cohesive failure %:
