ABSTRACT:
A method for improving the adhesion of organopolysiloxane elastomers to solid substrates which comprises (1) coating the substrate with a primer composition containing (a) a mixture consisting of a silane having an SiC-bonded aliphatic multiple bond and a silane having an SiC-bonded epoxy group; or (b) a stratum consisting of (i) at least a partially crosslinked organopolysiloxane containing SiO.sub.4/2 units, trimethylsiloxane units and vinyldimethylsiloxane units and (ii) at least a partially crosslinked organopolysiloxane elastomeric coating over said stratum, in which the organopolysiloxane elastomer is obtained from an organopolysiloxane composition which is stable under anhydrous conditions, but crosslinks when exposed to moisture at room temperature, (2) applying a crosslinkable organopolysiloxane composition over said primer, in which the crosslinkable organopolysiloxane composition contains a diorganopolysiloxane, a crosslinking agent, a catalyst and at least one additional component, in which the component is flowable after the composition has crosslinked and/or a rod-shaped copolymer obtained from the copolymerization of styrene and n-butylacrylate in the presence of a diorganopolysiloxane by means of free radicals.
