Abstract
Abstract A method for bonding substrates with silicone rubber substantially shortens the setting time and provides good bonding of the substrates with silicone rubber using a silicone rubber composition comprised of a thermal-crosslinking component and moisture-crosslinking component. The silicone composition is applied to a substrate, heated to give a silicone gel, subsequently brought into contact with another substrate, and is followed by moisture crosslinking to form a silicone rubber.

A method for bonding substrates with silicone rubber comprising coating a substrate with a silicone rubber composition comprising a thermal-crosslinking component that is an addition reaction-crosslinking silicone rubber composition comprising a polydiorganosiloxane that has at least 2 alkenyl groups in each molecule, an organosiloxane that has at least 2 silicon-bonded hydrogen in each molecule, and a hydrosilylation catalyst, and a moisture-crosslinking component comprising a combination of trialkoxysiloxy-terminated polydiorganosiloxane, curing catalyst, and organotrialkoxysilane, where the thermal-crosslinking component and moisture-crosslinking component are present in amounts such that heating the silicone rubber composition results in a silicone gel with a penetration of 10 to 600 according to JIS K 2207, and the silicone gel cures to a moisture cured silicone rubber with a hardness of 4 to 80 according to JIS K 6301 using the spring type A method, then heating the silicone rubber composition to give a silicone gel, then subsequently bringing another substrate into contact with the silicone gel, and finally forming a silicone rubber by moisture-crosslinking the silicone gel.
