Controlled Volatility Potting and Encapsulating Silicone Elastomer
DESCRIPTION
Two-part, white silicone system
Offers medium strength, low modulus, good physical properties and a broad operating temperature range
1:1 Mix Ratio (Part A:B)
APPLICATION
To provide protection of electric components and assemblies against shock, vibration, moisture, dust, chemicals and other environmental hazards
Ideal for adhesive applications where a large surface must be covered
For applications requiring minimal outgassing
