Silicon and nitrogen containing adhesion promoters and siloxane compositions containing them

摘要

Silicon- and nitrogen-containing compositions prepared by the reaction of an aminoalkylsilane such as 3-aminopropyl- or 3-methylaminopropyltrimethoxysilane with a glycidoxyalkylsilane such as 3-glycidoxypropyltrimethoxysilane are useful as adhesion promoters in addition curable polyorganosiloxane compositions. The latter are illustrated by mixtures of vinyl- substituted polyorganosiloxanes and hydride polyorganosiloxanes, also containing at least one platinum group metal compound as a hydrosilylation catalyst.
