Product Code:SAE AMS3362
Title:Silicone Rubber Compound Room Temperature Vulcanizing, 15,000 Centipoise Viscosity Durometer 35-55
Issuing Committee:Ams G9 Aerospace Sealing Committee
Scope:This specification covers a silicone rubber in the form of a two-component liquid compound. Primarily for potting or encasement of electrical and electronic components with an elastomeric medium or for production of mechanical rubber parts in low-pressure tooling. Elastomeric properties are retained in operation from -55 to +230 degrees C (-67 to +446 degrees F). For mechanical applications where compression set resistance is important, elevated temperature post-curing of parts may be required.
