Process for the manufacture of coatings from copolymers containing hydroxyl groups, which copolymers are reaction products of mixtures of styrene, methyl methacrylate, hydroxyethyl methacrylate, acrylic acid and glycidyl esters of aaa20-25.9% by weight of styrene, (b) 20-24% by weight of methyl meth
Process for the manufacture of coatings from copolymers containing hydroxyl groups, which copolymers are reaction products of mixtures of styrene, methyl methacrylate, hydroxyethyl methacrylate, acrylic acid and glycidyl esters of aaa20-25.9% by weight of styrene, (b) 20-24% by weight of methyl methacrylate, (c) 18-24% by weight of hydroxyethyl methacrylate, (d) 8.5-11% by weight of acrylic acid and (e) 29.0-35.0% by weight of glycidyl ester of aaa13H24O3 or wherein components d) and e) are incorporated as a prereacted product of the formula [Figure] wherein R is the radical of aaa10H19O2 in an amount of 37.5-46% by weight, and wherein the incorporated components (a), (b), (c), (d), and (e) have a total of 100% by weight, dissolved in a solvent containing no active hydrogen atoms, and (B) an organic polyisocyanate, the amount of the copolymer (A) and the polyisocyanate (B) in the coating mixture adding up to 100 percent by weight, and this mixture is shaped or applied to suitable substrate and the solvent is then removed, in order to obtain the finished coating.
