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
