  • Patent number: 11739235
    Abstract: The present invention relates to a process for preparing liquid compositions of etherified melamine formaldehyde resins, namely melamine formaldehyde resins etherified with a primary C1-C6-alkanol, which have low formaldehyde contents. The invention also relates to such liquid compositions of etherified melamine formaldehyde resins having a content of free formaldehyde of less than 0.3% by weight. The liquid compositions of etherified melamine formaldehyde resins are useful as crosslinking agents in coating compositions.

  • Patent number: 10604675
    Abstract: 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.
