A process (1) for coating plastic substrates comprises (a)coating the substrate with a mixt. (I) contg. (i) an epoxy prepolymer, (ii) an acrylic monomer, (iii) a hardener, (iv) a catalyst and (v) a graft polymerisation initiator, and (b) hardening the mixt. to bring about graft polymerisation with the substrate. Also claimed is a process (2) for protecting the surface of an elastomeric gaiter for a constant-velocity joint (see below). |
