Thermally Conductive

Thermally Conductive Controlled Volatility RTV Silicone

  • Two-part, white, thermally conductive RTV silicone
  • 100:0.2 Mix Ratio (Base: Curing Agent)
  • 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 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 non- flowable to limited flow material
  • For applications requiring a broader operating temperature range
