thermally conductive advancedengineering space





  • Two-part, white, thermally conductive silicone
  • Will cure 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 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 flowable to limited flow material

Meets or 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 ≤1% and CVCM of ≤0.1%
