Adhesives/Sealants

Controlled Volatility Potting and Encapsulating Silicone Elastomer

DESCRIPTION

Two-part, white silicone system
Offers a high tear strength, good physical properties and a broad operating temperature range
Convenient 1:1 mix ratio (Part A: Part B)

APPLICATION

For applications requiring low outgassing and minimal volatile condensables under extreme operating conditions
To provide protection of electric components and assemblies against shock, vibration, moisture, dust, chemicals and other environmental hazards
Ideal for use in potting connectors, cable harness breakouts, molded high-voltage terminals, seals and gaskets due to its high tear strength
For use as an adhesive
For applications requiring a broader operating temperature range
