Thermally Conductive

Controlled Volatility Electrically Conductive RTV Silicone

DESCRIPTION
  • Two-part, tan-colored electrically conductive RTV silicone
  • 100:0.5 Mix Ratio (Base: Curing Agent)
  • 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%
APPLICATION
  • For applications requiring low outgassing and minimal volatile condensables under extreme operating conditions to avoid condensation in sensitive devices
  • Use for RFI and EMI shielding in electronic and space applications
  • Use to adhere covers onto housings or for any application where grooves and other configurations require a non- flowable to limited flow material
  • For applications requiring a broader operating temperature range
