Tosseal 381 One Part Neutral Cure Silicone Sealant

TOSSEAL 381 is a one component silicone sealant which cures to a high modulus silicone rubber on exposure to atmospheric moisture at room temperature. This product is a ketoxime cure sealant which does not emit the odors associated with acetoxy cure sealant, and is virtually non-corrosive to metal. In addition to the unique features of silicone rubber such as superior high and low temperature resistance, water resistance, and outstanding weatherability, TOSSEAL 381 also provides excellent adhesion to glass, metal, concrete and numerous construction materials. This product is highly suitable for application in glass-to-glass or glass-to-aluminum sash bonding and use on prefabricated housing.
