Silicone Encapsulating & Potting Sealants & AdhesivesOur silicone potting and encapsulating
sealants and adhesives have exceptionally high impact, temperature, and
chemical resistance, making them the ideal choice for protecting electrical components.
What is meant by
silicone encapsulating and potting?
Potting is a process where a sensitive
component – such as an electronic component – is covered with a protective
sealant to safeguard it from potential environmental threats. The most common
threats that potting protects components against include moisture and water or
for electrical insulation. However, potting is also used to protect printed
circuit boards and other components against physical and thermal shock,
tampering, and chemical attack. Potting sealant can also act as a visual and
physical shield that protects consumer information and intellectual property.
'Potting' and 'encapsulating' are terms that
are used interchangeably. However, technically, potting is a process where the
"pot" or shell filled with the resin /potting sealant becomes part of
the component.
In encapsulation, the hardened potting sealant
and the component are removed from the shell or pot and utilized in the
assembly. A similar process is used in conformal coatings that protect against
environmental threats, although this method's protection is less than optimal.
Potting and encapsulation can both be utilized in conjunction, while each
process has its specific applications.
When it comes to potting and encapsulating
electronic components and other applications, silicone is the preferred
material. Silicone as a potting sealant or electronic encapsulating using
silicone is a process that is well established due to its ability to protect
delicate circuitry.
Silicone potting protects against multiple
threats, including thermal shock, mechanical shock, chemical attack, vibration,
extreme temperatures, broad thermal cycles, and humidity, to name a few.
In addition to protection, the encapsulation
silicone can also be leveraged to perform other functions, including light
emission and thermal transfer.
Silicone encapsulating and potting sealants
and adhesives fill a chamber or flow around or over a component to protect its
components.
An exclusive range of
potting and encapsulating silicone adhesives and sealants
Although the intended end function appears
straightforward and simple, complex methods are often used to design and
produce delicate or sensitive components. To meet the stringent demands in
various industries for component protection, the potting sealant or
encapsulation silicone needs to be of the highest quality.
At Exonic Polymers, all our silicone products
– be it RTV potting sealant or electronics encapsulating silicone or other
sealants – go through meticulous product development, selection, and quality
testing procedures.
To meet the industry's demands, a silicone
potting sealant must be highly elongated apart from being durable, flexible,
and fast. Potting adhesives made of silicone fill gaps around and within
components while curing in quick time.

Encapsulating silicone products specially designed for industry's needs
Low viscosity silicone sealants
Neutral-cure potting silicone sealants that are free-flowing and feature low viscosity fill minute voids and crevices. Ideally designed for encapsulating and potting applications, our product offers superior resistance against temperature extremes, moisture, ozone, vibration, and weathering. Exonic 2-Part Pourable Silicone Coating is a pourable silicone coating that provides a fast-curing rubber coating ideal for shock dampening and vibration isolation applications. The self-leveling potting sealant meets industry requirements for fast and deep section RT curing and optimal electrical potting, electronic component encapsulation, thermal insulation, moisture, and vibration insulation.
Deep section curing
Our Room Temperature Vulcanizing or RTV potting sealants are quick curing and offer outstanding adhesion to glass, plastic, and metal. For instance, Exonic Polymers Deep Section Liquid Adhesive Silicone Sealant is a 2-part, Platinum cure RTV silicone sealant that reaches the deep section to provide extensive adhesion. The product is an excellent encapsulation silicone while used in numerous coating applications.
Clear encapsulation or potting of components
Exonic Polymers series of clear silicone encapsulating and potting sealants are designed for niche applications. Whether it is bonding surfaces on LCDs, flat-screen panels, and LED encapsulation, you can find the right solutions with us. Optically clear silicones offer UV resistance and are ideal for outdoor signage, display, and PV module manufacturing.
