Form; This specification covers a room temperature vulcanizing silicone rubber in the form of a two-component liquid compound. Application: 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??o +230??{-65??o +445??. For mechanical applications where compression set resistance is important@ elevated temperature post-curing of parts may be required.
