Clearcoat coating materials for plastic parts

Abstract

Disclosed herein is an protic solvent-based two-pack clearcoat coating material, including: a master batch component including one or more poly(meth)acrylate polyols A, the poly(meth)acrylate polyols A having a hydroxyl value in the range from 160 to 240 mg KOH/g and a weight-average molecular weight in the range from 1000 to 7000 g/mol; and one or more catalysts C for crosslinking hydroxyl groups with free isocyanate groups; and including a hardener component including one or more curing agents B selected from the group consisting of diisocyanates and polyisocyanates; and one or more organic solvents, which can be contained in the master batch component, the hardener component, or in the master batch component and in the hardener component. Also described herein are a method of coating substrates with the coating material and a method of using the coating material in coating substrates.
