Abstract
An organopolysiloxane composition for surface treatment comprising (A) a reaction product of (1) a silane and/or a siloxane each having a substituted or unsubstituted amino group bonded to the silicon atom via at least one carbon atom and also having an alkoxy group bonded to the silicon atom and (2) a silane and/or a siloxane each having a monovalent hydrocarbon group bonded to the silicon atom, the hydrocarbon group being substituted with an epoxy-containing group, and an alkoxy group bonded to the silicon atom and (B) a specific organopolysiloxane containing an amino group. The composition provides a non-sticky, water-repellent and slippery film on a substrate, especially an EPDM rubber sheet and EPDM molded sponge, with markedly improved adhesion.
