Primer compositions for pretreatment or fitting of coatings and processes for treating them

摘要

Primer composition for the pretreatment of coatings, comprising at least one polymer chosen from among a graft polymer of an unsaturated dicarboxylic acid and an ethylene/vinyl acetate copolymer, a chlorinated polypropylene in which a graft polymer of an unsaturated dicarboxylic acid and of propylene is subjected to chlorine substitution or a chlorinated polypropylene in which the polypropylene is simply subjected to chlorine substitution, and a graft polymer of an unsaturated dicarboxylic acid and an ethylene/ethyl acrylate copolymer or a chlorination product of the graft polymer, and a solvent.
