Thermally Conductive

Thermally Conductive Controlled Volatility Silicone Elastomer

  • Two-part, white, thermally conductive, low viscosity silicone elastomer
  • Cures with the addition of heat
  • 1:1 Mix Ratio (Part A: Part B)
  • For applications requiring low outgassing and minimal volatile condensables under extreme operating conditions
  • To provide heat transfer between electrical/electronic components and their heat sinks
  • Use to adhere integrated circuit substrates, base plates, heat sinks or where grooves or other configurations require a limited flow material
