• Two-part, white, thermally conductive silicone
  • Cures with the addition of heat
  • Designed to allow bond line thicknesses - 50 micron to reduce thermal resistance
  • 20:1 Mix Ratio (Part A: Part B)


  • For applications requiring low volatility under extreme operating conditions to avoid contamination in sensitive devices
  • To provide heat transfer between electrical/electronic components and their heat sinks while remaining electrically insulating
  • Use to adhere integrated circuit substrates, base plates, heat sinks or where grooves or other configurations require a non-flowable to limited flow material
