ABSTRACT:
High-solids binder combinations comprising polyisocyanates, special lactone-based polyols and polyacrylate-polyols, a process for preparing such binders, and their use for producing coatings.The lactone-based polyols include ε-caprolactone-based polyols having an average hydroxy functionality ≧2 and a number-average molecular weight of from 119 to 2000 g/mol. The polyacrylate resins are prepared by copolymerizing optionally functional polybutadienes, aromatic monomers, hydroxyalkyl esters of acrylic or methacrylic acid having primary hydroxyl groups, aliphatic esters of acrylic or methacrylic acid and C1to C8monoalcohols, α,β-unsaturated C3–C7monocarboxylic or dicarboxylic acids or of one or more monoesters of maleic acid or fumaric acid and C1to C14monoalchols.
