Coating materials that can be cured thermally and by actinic radiation, and the use thereof

摘要

Coating materials curable thermally and with actinic radiation, comprising (A) binder selected from the group consisting of random, alternating and block, linear, branched and comb polyaddition resins, polycondensation resins, and addition (co)polymers of olefinically unsaturated monomers, curable physically, thermally, with actinic radiation and thermally and with actinic radiation; and (B) from 0.2 to 20% by weight, based on the solids of the coating material, of at least one polyisocyanate which is free from blocking agents and by means of internal formation of uretdione groups is blocked up to a reelimination temperature of at least 160° C.; and their use for producing single-coat and multicoat clearcoat systems and multicoat color and/or effect paint systems or as adhesives and sealing compounds.
