Water-free high-solids base paints, the production thereof and the use thereof for producing multilayer paint coatings, and multilayer paint coatings comprising a base coating made of a water-free high-solids base paint

摘要

A waterless high-solids basecoat material having a solids content of at least 35% by weight, comprising (a) 1% to 10% by weight of at least one polyester binder with an acid number of at least 20 mg KOH/g, (b) 10% to 30% by weight of at least one acrylate binder, (c) 12% to 30% by weight of at least one kind of polymer microparticles, (d) 9.5% to 30% by weight of at least one crosslinking agent selected from free isocyanates, blocked isocyanates, and amino resins, (e) 1% to 3% by weight of at least one sulfonic acid catalyst, (f) 1% to 35% by weight of at least one pigment, (g) 30% to 65% by weight of at least one organic solvent, and (h) 0.5% to 47% by weight of at least one auxiliary or additive, based in each case on the total weight of the basecoat material.
