Controlled Volatility Silicone

DESCRIPTION
  • Two-part, optically clear silicone system
  • Low viscosity
  • Convenient 1:1 mix ratio (Part A:B)
APPLICATION
  • For applications requiring low outgassing and minimal volatile condensables under extreme operating conditions
  • As an embedding or potting compound for electronic assemblies and components to provide protection from extremes in humidity, radiation, thermal stress and mechanical stress
  • Suitable as an adhesive in applications such as solar cell arrays where clarity and low volatility are important
  • For applications requiring a low viscosity for superior flow
