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 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.
