BOSS 322 100% RTV Silicone Sealant is a paste like, one component material which cures to a tough, rubbery solid when exposed to moisture in the air. Since it will not flow of its own weight, this sealant can be applied overhead or on side wall joints and surfaces without sagging, slumping or running off. It will adhere to clean metal, glass, most types of wood, silicone resin, vulcanized silicone rubber, ceramic, natural and synthetic fiber, as well as painted and many plastic surfaces. BOSS 322 100% RTV Silicone Sealant has good resistance to weathering, vibration, moisture, ozone and extreme temperatures. It may be applied in sub zero weather without loss of extrusion or physical property characteristics. Fully cured BOSS 322 can be used for extended periods at temperatures up to 450 degree F (232 degree C),and for shorter periods as high as 500 degreeF (260 degree C). Tests have shown that even after two months at 450 degreeF (232 degree C), or up to one week at500 degree F (260 degree C), the sealant remains rubbery.
