COATING AGENT- THE MANUFACTURE AND USE THEREOF

摘要

The invention relates to a coating agent for multi-layer enamel with a bonding agent composition containing: a) 25-75 wt. % carboxy-functional (meth)acryl copolymers and/or carboxy-functional polyesters, whose carboxy-functionality corresponds to an acid number ranging from 15-300 mg KOH/g; b) 25-75 wt. % epoxide functionalized cross-linking agent resins of which at least one is a (meth)acryl copolymer produced by additionally using a tertiary butyl (meth)acrylate; c) 0-60 wt % polyols with at least two hydroxyl functions in the molecule; d) 0-40 wt % constituents cross-linking with hydroxyl groups and thus forming ether and/or a triazine-based cross-linking agent; e) 0-40 wt. % polyisocyanates; f) 0-60 wt. % of at least one organic polyanhydride with at least two cyclic carboxylic acid anhydride groups per molecule; g) 0-20 wt. % reactive diluent with an epoxy function; h) 0-10 wt. % catalysts for the reaction of the carboxyl and epoxide groups.
