Thermally Conductive

Thermally Conductive Controlled Volatility Silicone

  • Two-part, white, thermally conductive silicone
  • Cures with the addition of heat
  • Mix Ratio 10:1 (Part A:B)
  • Designed for enhanced performance in extreme low and high temperatures
  • For applications requiring low outgassing and minimal volatile condensables under extreme operating conditions to avoid condensation in sensitive devices
  • To provide moderate heat transfer between electrical/electronic components and their heat sinks
  • Use for adhering openings in modules and housings where grooves or other configurations require a limited flow material
  • For applications requiring a broader operating temperature range
