Silicone Encapsulating & Potting Sealants & Adhesives
Our 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
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
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
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.
