ADHESION PROMOTER AND CURABLE ORGANOPOLYSILOXANE COMPOSITION CONTAINING SAME

摘要

The present invention provides an adhesion promoter that can achieve excellent initial adhesion improvement effects towards various types of substrates, a curable organopolysiloxane composition containing this adhesion promoter, and a protective agent or adhesive composition for electric and electronic components. An adhesion promoter containing the following components (A) to (C) in a specific weight ratio, a curable organopolysiloxane composition containing this adhesion promoter, and a particular agent for electric and electronic components:
(A) A reaction mixture of an organoalkoxysilane having an amino group and an organoalkoxysilane having an epoxy group; (B) An organic compound having at least two alkoxysilyl groups in a molecule and having a bond other than a silicone-oxygen bond between these silyl groups; (C) a silane containing an epoxy group or a partially hydrolyzed condensate thereof.
