Multicomponent coating materials, adhesives and sealing compounds comprising a (meth)acrylate (A) containing, based on (A), up to 90% by weight of hydroxyl-containing monomers in copolymerized form, of which (a1) from 20-90% by weight, based on (A), are 4-hydroxybutyl (meth)acrylate and/or 2-alkylpropane-1,3-diol mono(meth)acrylate, and (a2) from 0-40% by weight based on (A), are other hydroxyl-containing monomers; and (B) an adduct preparable from (b1) a diisocyanate, and (b2) a compound of the general formula I having an isocyanate-reactive group:wherein R<1 >and R<2 >are hydrogen or alkyl radicals, X and Y are oxygen, sulfur or >N-R<6 >where R<6 >is alkyl radical or aryl radical, R<3 >is alkylene radical and R<4 >and R<5 >are hydrogen, isocyanate-reactive groups or radicals R<6>; where R<4>, R<5 >or R<6 >contains an isocyanate-reactive group or R<4 >or R<5 >is an isocyanate-reactive functional group, and where R<4>, R<5 >or R<6>, where present, contain no isocyanate-reactive groups and the molar ratio of isocyanate groups in (b1) to the isocyanate-reactive groups in the compound I is 1.0.
