Ultra Low Outgassing™ Black Silicone

  • Two-part, low viscosity, black silicone system
  • Offers a broad operating temperature range
  • 10:1 Mix Ratio (Part A:B)
  • For electronic and space applications requiring Ultra Low Outgassing™ and minimal volatile condensables to avoid condensation in sensitive devices
  • 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
  • As an adhesive in optical applications requiring a black material to block light
