Abstract

A process for improving the adhesion of an organopolysiloxane elastomer to a substrate which comprises (1) coating the substrate with a copolymer containing (a) 2-hydroxypropyl acrylate and/or 2-hydroxypropyl methacrylate and (b) at least one olefinically unsaturated monomer, (2) applying a room temperature vulcanizable organopolysiloxane composition to the coated substrate and thereafter (3) curing the organopolysiloxane composition.
