Abstract
Compositions comprising (B1) at least one polyisocyanate-group-containing compound (B1) having free or blocked isocyanate groups and a cycloaliphatic polyisocyanate parent structure, and/or a polyisocyanate derived therefrom, and (B2) at least one polyisocyanate-group-containing compound (B2) having free or blocked isocyanate groups and an acyclic, aliphatic polyisocyanate parent structure, and/or a polyisocyanate derived therefrom, where at least one of component (B1) and component (B2) comprise at least one structural unit selected from the group of structural unit (I)—NR—(X—SiR″(OR')3-)  (I),structural unit (II)—N(X—SiR″(OR′)3-)(X′—SiR″(OR′)3-)  (II),and mixtures of two or more of the foregoing, wherein the compound (B1) is in an amount such that the binder fraction of the compound (B1) is between 5% and 45% by weight, based on the sum of the binder fraction of the compound (B1) and of the compound (B2), and the mixture of components (B1) and (B2) includes structural units (I) and structural units (II).
