Abstract
A two-component coating composition contains (1) a paint base component comprising (A) at least one polycarbonate diol, (B) at least one hydroxyl-containing acrylate resin, polyester resin and/or polyester acrylate resin having a hydroxyl number of 75 to 500 mg KOH/g, and (C) at least one filler modified with at least one organosilane, and (2) a hardener component comprising (D) at least one organic polyisocyanate, where the coating composition has a viscosity of 50 to 2000 mPa·s at a shear stress of 1000 l/s and a temperature of 23° C. and a proportion of organic solvents of 100 to 350 g/L.
