CV-2942

THERMALLY CONDUCTIVE, CONTROLLED VOLATILITY SILICONE

 

Description

  • Two-part, gray, thermally conductive silicone
  • Based on a dimethyl silicone polymer
  • Uses a platinum-catalyzed addition cure
  • 20:1 Mix Ratio (Part A:B)

Applications

  • 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 to adhere openings in modules or housings where grooves and other configurations require a non-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%
