Production and use of cold plastic coating compositions based on acrylic resins

摘要

Binder for road marking paints, containing a (meth) acrylate copolymer A and one or more olefinically unsaturated monomers B, which can be hardened by the addition of radical initiators C, characterized in that the binders have a mass fraction of 20 to 80% of the (meth) acrylate copolymer A and 80 contain up to 20% of the olefinically unsaturated monomers B, the (meth) acrylate copolymers A being obtainable by reacting mass fractions of DOLLAR A - 10 to 50% of compounds A1, selected from monoepoxides, lactones and lactams with 4 to 18 carbon atoms, and DOLLAR A - 1 to 25% of olefinically unsaturated monomers A2 which contain at least one acid group selected from carboxyl groups, sulfonic acid groups and phosphonic acid groups, DOLLAR A - 5 to 70% of esters A3 of methacrylic acid with linear, branched or cyclic alcohols with 1 to 20 Carbon atoms and DOLLAR A - 2 to 84% of esters A4 of acrylic acid with linear, ver branched or cyclic alcohols with 2 to 20 carbon atoms and optionally DOLLAR A - up to 70% of other vinyl monomers A5 DOLLAR A with free-radical polymerization, the compounds A1 being introduced and the monomers A2 to A5 and a free-radical initiator A7 being added.
