Controlled Volatility Silicone Elastomer

  • Two-part, low viscosity clear RTV silicone
  • Designed for enhanced performance in extreme low and high temperatures
  • 10:1 Mix Ratio (Part A:Part B)
  • For applications requiring low outgassing and minimal volatile condensables under extreme operating conditions
  • As an embedding or potting compound for environmental protection of electronic assemblies and components
  • Provides protection from extremes in temperature, humidity, radiation, thermal stress and mechanical stress
  • Low viscosity for applications requiring superior flow
