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.
Claims22
A process for improving the adhesion of an organopolysiloxane elastomer to a substrate, which comprises (1) coating the substrate with a copolymer containing a compound selected from the class consisting of (a) 2-hydroxypropyl acrylate, 2-hydroxypropyl methacrylate and mixtures thereof, and (b) at least one other olefinically unsaturated monomer, (2) subsequently applying to the substrate a room temperature vulcanizable organopolysiloxane composition, and thereafter (3) curing the organopolysiloxane composition.
