• Two-part, white, flowable, thermally conductive silicone
  • Cures with the addition of heat
  • 10:1 Mix Ratio (Part A:Part B)


  • 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 housing where grooves or other configurations require a limited flow material
