COATING SYSTEM FOR PRODUCING COLOR- AND/OR EFFECT-IMPARTING MULTILAYER COATINGS ON THE BASIS OF MULTI-COMPONENT COATING MATERIALS

摘要

The invention relates to an integrated coating system for producing color- and/or effect-imparting multilayer coatings on primed and unprimed substrates, comprising (I) a multi-component filler, containing a component that comprises isocyanate-reactive groups, fillers and polyisocyanates, (II) optionally a multi-component coating lacquer, containing a component that comprises isocyanate-reactive groups, color-imparting pigments and polyisocyanates, and (III) a multi-component clearcoat, containing at least one component that comprises isocyanate-reactive groups and polyisocyanates. For producing said multi-component coatings, the same polyisocyanate and the same diluent are continuously used and the clearcoat (III) used is a solvent-containing multi-component system that can be cured thermally and by actinic radiation (dual cure). Said multi-component system comprises (A) a component, containing (A1) a component that comprises isocyanate-reactive functional groups, (A2) a component that comprises isocyanate-reactive functional groups and at least one functional group with a bond that can be activated by actinic radiation, and (B) a component that contains a polyisocyanate (B1).
