  • Coating material compositions, coatings made therefrom and exhibiting high scratch resistance and good polishability, and use thereof
    Patent number: 9909029
    Abstract: Disclosed are nonaqueous coating material compositions comprising (A) at least one polyhydroxyl-group-containing compound, (B) at least one polyisocyanate-group-containing compound having free or blocked isocyanate groups, and (D) at least one catalyst for the crosslinking of silane groups, where component (B) comprises at least one 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 30 mol % 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 36 mol % of the originally present isocyanate groups have undergone reaction to form structural 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.
