摘要：One- or two-component polyurethane coating materials (PUCM), contg. at leastone component which is reactive towards polyisocyanates, contain a cpd. (A) with a NCOgp., a urethane, thiourethane or urea gp. and two capped gps. which are reactive towardsisocyanate. Also claimed are (i) addition prods. of 1 mole di-isocyanate and 1 mole of adioxolane or dioxan cpd., and (ii) substrates coated with PUCM. Cpd. (A) is the additionprod. of 1 mole di-isocyanate and 1 mole of a cpd. of formula (I), in which R<1>, R<2> =H or 1-10C alkyl; X, Y = O, S or NR<6>; R<3> = 1-5C alkylene, and the heterocyclic ringmay be substd. with other gps. R<4> and R<5>, where one of the gps. R<4>, R<5> orR<6> is or contains a NCO-reactive gp. such as OH, SH or prim. or sec. amino, and theothers (if present) contain no NCO-reactive gps. Pref. (I) are dioxolanes of formula (II),dioxans of formula (III) or oxazolidine derivs. of formula (IV), in which R<8>, R<9>, R<10>= H or 1-10C alkyl; R<7> = 1-30C aliphatic or aromatic residue substd. with a NCO-reactive gp. such as OH, SH or prim. or sec. amino, and opt. contg. ether gps. in thealiphatic type. 1-100 wt% of the reactive component in the PUCM consists of cpds. (A).
