Document Type and Number:
Japanese Patent JP6324985
Kind Code:
B2
Abstract:
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).
