摘要： The present invention relates to fast-drying, hard-elastic, scratch-resistant, and robust two-component polyurethane coating compositions, to their use, and to coating methods. Synthesis components in the coating compositions comprise polyisocyanate, hydroxyl-containing poly(meth)acrylate polyol, and certain branched polyester polyols, obtainable by polycondensation of hexahydrophthalic anhydride, trimethylolpropane, and optionally further components.
