POLYURETHANE COATING MATERIAL COMPOSITION, MULTISTAGE COATING METHODS USING THESE COATING MATERIAL COMPOSITIONS, AND ALSO THE USE OF THE COATING MATERIAL COMPOSITION AS CLEARCOAT MATERIAL AND PIGMENTED COATING MATERIAL, AND APPLICATION OF THE COATING METHOD FOR AUTOMOTIVE REFINISH AND/OR FOR THE COATING OF PLASTICS SUBSTRATES AND/OR OF UTILITY VEHICLES
The present invention relates to coating material compositions comprising at least one polyhydroxyl group-containing compound (A), at least one polyisocyanate group-containing compound (B) having free and/or blocked isocyanate groups, and at least one catalyst (D) based on a zinc-amidine complex which is prepared by reaction of 1.0 moles of at least one zinc(II) biscarboxylate with less than 2.0 moles of at least one amidine where 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 an aryl radical.
