Coatings composed of (A) a copolymer prepared by copolymerizing (1) a silicone macromer having a double bond at one end of the molecule, (2) an unsaturated monomer having on the molecule both a carboxyl or acid anhydride group and a double bond, (3) an unsaturated silane monomer having on the molecule both a hydrolyzable silyl group and a double bond, (4) an unsaturated monomer having on the molecule both an amide, imide, carbamate or urea group and a double bond and, optionally, (5) another copolymerizable unsaturated monomer; in combination with (B) a crosslinking catalyst provide crosslinked coats which have an adhesion to substrates and a toughness comparable to isocyanate-crosslinked coats and which are also endowed with excellent lubricity.
