1.1 ,The specification covers a two-part flowable space grade room temperature vulcanizing (RTV) silicone rubber adhesive or compound. The material is specifically designed for applications requiring extreme low temperature, low outgassing and minimal volatile condensibles under extreme operating conditions. The RTV silicone rubber should be suitable for withstanding environmental exposure to temperatures from –,115 to 200°,C (–,175 to 392°,F). The material should also withstand the combination of stress, temperature, and relative humidity expected to be encountered in service. The RTV silicone rubber may be used as a sealing, caulking, potting or bonding material for applications on metal, plastics, rubber, glass, and ceramic products. Types I and II are often used as coatings.
