Abstract

The primer compositions consist essentially of a mercapto-containing organosilane or organopolysiloxane as one component and a titanic acid ester as the other. They are suitable for adhesively bonding a room-temperature-curing silicone rubber elastomer irrespective of its crosslinking mechanism to various substrates. The bond obtained by use of the primer composition is very strong and highly resistant to water or sea water even on prolonged immersion at high temperatures.
