Polyurethane coating agent compositions, multi-stage coating methods |
摘要 |
The present invention relates to non-aqueous coating agent compositions containing (A) at least one polyhydroxyl group-containing compound, (B) at least one polyisocyanate group-containing compound having free or blocked isocyanate groups, (D) at least one catalyst (D) on the basis of a zinc-amidine complex which can be produced by the reaction of one or more zinc(II)bis-carboxylates with an amidine of formula (I) or with a mixture of two or more amidines of formula (I), and (S) at least one monomeric aromatic, optionally substituted carboxylic acid (S), the carboxyl group of which is in conjugation with a &pgr;-electron system, wherein the component (B) contains at least one structural unit -NR-(X-SiR''x(OR')3-x) (II) and/or at least one structural unit -N(X-SiR''x(OR')3-x)n(X'-SiR''y(OR')3-y)m (III). The present invention further relates to multi-stage coating methods and to the use of the coating agent compositions. |
