Description Non-Silicone Silicone

Non-Silicone Grease


AOS Heat Sink Compound: 52022 (AOS 300)
The original non-silicone thermal grease, developed for AT&T in the early 1970’s. Meets specifications for KS 21343 and Mil-C-47113 Type II. More stable and less prone to phase separation than other (non-silicone reproductions). Progressively softer variants are available, 52399 (320), 53300 (370), 52032 (400).
