CV-2946

THERMALLY CONDUCTIVE, CONTROLLED VOLATILITY SILICONE

Description

  • Two-part, white, thermally conductive silicone
  • Cures with the addition of heat
  • 15:1 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 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
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%
