摘要：Disclosed are nonaqueous coating material compositions comprising (A) at leastone polyhydroxyl-group-containing compound, (B) at least one polyisocyanate-group-containing compound having free or blocked isocyanate groups, and (D) at least onecatalyst for the crosslinking of silane groups, where component (B) comprises at leastone structural unit —NR—(X—SiR″x(OR′)3-x) (I), and at least one structural unit —N(X—SiR″x(OR′)3-x)n(X′—SiR″y(OR′)3-y)m (II), wherein in component (B) (i) more than 30mol % and less than 70 mol % of the originally present isocyanate groups have
undergone reaction to form structural units (I) and (II), (ii) more than 25 and less than 36mol % of the originally present isocyanate groups have undergone reaction to formstructural units (II), and (iii) component (B) has at least one polyisocyanate group-containing compound (B2) having free or blocked isocyanate groups and having an acyclic,aliphatic polyisocyanate parent structure.
