thermally conductive advancedengineering electronics/optoelectronics/space




Primed w/CF1-135, Contains Boron Nitride


  • Two-part, white, thermally conductive silicone
  • Cures with the addition of heat
  • 15:1 Mix Ratio (Part A:B)


  • For applications requiring Ultra Low OutgassingTM 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

Exceeds the ASTM E 595 low outgas specifications outlined in NASA SP-R-0022A and European Space Agency PSS-014-702, with a TML of ≤0.1% and CVCM of ≤0.010%
