摘要
The present invention provides nonaqueous coating material compositions, multistage coating processes and also the use of the coating material compositions, comprising(A) at least one polyhydroxyl-group-containing compound,(B1) at least one polyisocyanate-group-containing compound (B1) having free or blocked isocyanate groups and having a cycloaliphatic polyisocyanate parent structure, and/or a polyisocyanate derived therefrom,(B2) at least one polyisocyanate-group-containing compound (B2) having free or blocked isocyanate groups and having an acyclic, aliphatic polyisocyanate parent structure, and/or a polyisocyanate derived therefrom,(D) at least one catalyst for the crosslinking of silane groups,and(R) at least one rheological assistant (R) based on fumed silica, where component (B1) and/or component (B2) comprise at least one structural unit—NR—(X—SiR″x(OR′)3-x) (I),and/or at least one structural unit—N(X—SiR″x(OR′)3-x)n(X′—SiR″y(OR′)3-y)m (II).展开▼
