Abstract
A self-bonding room temperature vulcanizable silicone rubber composition comprising a silanol-terminated diorganopolysiloxane base polymer, a filler, a crosslinking agent selected from carboxyl functional silanes and hydrocarbonoxy functional silanes, a curing catalyst and as the self-bonding additive a silyl maleate or a silyl fumarate or a silyl succinate. In place of the foregoing silane self-bonding additives there may be utilized as a self-bonding additive, a maleate functional polysiloxane, a fumarate functional polysiloxane or a succinate functional polysiloxane.
