  • Coating material compositions and coatings produced therefrom combining high scratch resistance and good polishability and good optical properties, and use thereof
    Patent number: 10100222
    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).
