摘要

patent summary: "polyurethane based coating material composition, multistage coating methods using such coating material compositions, and also the use of coating material composition as transparent coating material and pigmented coating material, and application of the coating method for automotive refinishing and / or coating of plastic substrates and / or utility vehicles ". The present invention relates to coating material compositions comprising at least one compound (a) containing iphydroxyl groups, at least one compound (b) containing polyisocyanate groups having free and / or blocked isocyanate groups. , and at least one catalyst (d) based on a zinc-amidine complex which can be prepared by reacting 1.0 mol of at least one zinc biscarboxylate (ii) with less than 2.0 moles of at least least one amidine wherein r5 = hydrogen and r1, r2, r3 and r4 are each identical or different radicals, r1 and r3 being hydrogen or an alkyl radical or an aryl radical, and r2 and r4 being an alkyl radical or a Aryl radical. The present invention further provides multistage coating methods using such coating material compositions, and also the use of coating material compositions as a transparent coating material and application of the coating method in automotive refinishing and / or coating. plastic substrates and / or commercial vehicles.
