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.

Quick-drying, energy-elastic, scratch-resistant and stable coating compounds

Process for the preparation of etherified melamine/formaldehyde condensates, in which first a methylolation of melamine with a formaldehyde component in the molar ratio of from 1:6 to 1:15, preferably at a pH of &#x3e;7, is carried out. This is followed by an etherification of the resulting hydroxymethylation intermediate in the presence of a C-C-alkyl, preferably of a C-C-alcohol, particularly preferably of a C-C-alcohol, at a pH of &#x3c;4.5, and subsequently by at least one distillation step in order to remove in particular methanol from the system, the pH of &#x3e;9.5 being established before, during and/or after the distillation. According to the invention, a plurality of hydroxymethylation, etherification and distillation steps follow in order to achieve an etherified melamine/formaldehyde condensate which is distinguished by a high degree of hydroxymethylation, a high solids content and a low viscosity.
