• Two-part, electrically conductive RTV silicone colored green-gray
  • Maintains electric conductivity over a broad operating temperature range
  • 100:0.5 Mix Ratio (Base: Curing Agent)
  • Designed for enhanced performance in extreme low and high temperatures


  • 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
  • Well suited for formed-in-place conductive gaskets
  • For applications requiring a broader operating temperature range
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%
