Thermally Conductive Controlled Volatility RTV Silicone
DESCRIPTION
Two-part, gray, thermally conductive RTV silicone
100:0.2 Mix Ratio (Base: Curing Agent)
Designed for enhanced performance in extreme low and high temperatures
APPLICATION
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 limited flow material
For applications requiring a broader operating temperature range
