Description
- Two-part, gray, thermally conductive silicone
- Based on a dimethyl silicone polymer
- Uses a platinum-catalyzed addition cure
- 20:1 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 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 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%
