摘要 |
<p>A method for improving the adhesion of elastomers derived from compositions which are crosslinked by a condensation reaction and which are based on diorganopolysiloxanes containing rod-shaped copolymers formed by the free-radical copolymerization of styrene and (meth)acrylic acid ester in the presence of the diorganopolysiloxanes, to an undercoating consisting of an epoxy resin and pitch or tar, which comprises applying a primer having SiC-bonded organic groups to the undercoating prior to the application of the crosslinkable composition, in which the primer consists of a solution of (a) a copolymer of a (meth)acrylic acid ester free of silicon atoms and a (meth)acryloxyalkylsilane containing at least one SiOC-bonded monovalent organic group; and (b) a silane which contains a SiC-bonded organic group having at least one amino or imino group and which contains at least one SiOC-bonded monovalent organic group and/or a partial hydrolyzate of such silane in an organic solvent.</p> |
