    Abstract: The present invention relates to non-aqueous coating material compositions containing (A) at least one polyhydroxyl group-containing component (A); (B1) at least one isocyanate and silane group-containing component (B1); and (D) at least one catalyst (D) for the cross-linking of silane groups, characterized in that they (B2) comprise at least one isocyanate group-containing component (B2) which is different from component (B1) and comprises in addition at least one perfluoroalkyl group of the formula (I) CR
    1
    3 -(CR
    2
    2 )
    f -, wherein R
    1 , R
    2 are independently from one another H, F and/or CF
    3 , but R
    1 and R
    2 cannot be simultaneously H, and f = 1 to 20, preferably f = 3 to 11, particularly preferably f = 5 to 7. The invention further relates to coatings produced from these coating material compositions and the use thereof.

    Abstract translation: 本发明涉及非水涂料组合物,其含有(A)至少一种含多羟基的组分(A); (B1)至少一种含异氰酸酯和硅烷基团的组分(B1); 和(D)至少一种用于交联硅烷基团的催化剂(D),其特征在于它们(B2)包含至少一种不同于组分(B1)的含异氰酸酯基团的组分(B2)并且包含 加成至少一个式(I)CR 1 3-(CR 2 2)f-的全氟烷基,其中R 1,R 2彼此独立地为H,F和/或CF 3,但是R 1和R 2 不能同时为H,并且f = 1至20,优选f = 3至11,特别优选f = 5至7.本发明还涉及由这些涂料组合物制备的涂料及其用途。
