摘要： The present invention relates to nonaqueous coating material compositions comprising (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 crosslinking of silane groups, which composition comprises (B2) at least one isocyanate group-containing component (B2) which is different from component (B1) and which additionally has at least one perfluoroalkyl group of the formula (I) CR13—(CR22)f—  (I) where R1 and R2 independently of one another are H, F and/or CF3, but R1 and R2 may not both be H, and f is 1 to 20, preferably 3 to 11, more preferably 5 to 7. A further subject of the present invention are the coatings produced from these coating material compositions, and also their use.

摘要： The present invention relates to a method for producing coatings on metal surfaces, wherein an optionally precoated metal surface has applied to it a coating material composition (K) which comprises a) at least one polyhydroxyl group-containing component (A), b) at least one component (B) having on average at least one free and/or blocked isocyanate group and having on average at least one hydrolyzable silane group of the formula (I) —N(X—SiR″x(OR′)3-x)n(X′—SiR″y(OR′)3-y)m  (I) c) and at least one phosphorus-containing catalyst (D) for the crosslinking of silane groups, which comprises i. applying the coating material composition (K) to wheel rims, ii. 5 to 50 mol % of the isocyanate groups originally present in component (B) having undergone reaction to form silane groups of the formula (I), and iii. the phosphorus-containing catalyst (D) being selected from the group of phosphorus-containing acids and/or the partial esters of phosphorus-containing acids. The present invention further provides the coatings obtainable by this method and also the use thereof.

摘要： The present invention relates to a method for producing dirt-repellent coatings on metal surfaces, more particularly on wheel rims, wherein an optionally precoated metal surface has applied to it a coating material composition (K) which comprises a) at least one polyhydroxyl group-containing component (A), b) at least one component (B) having on average at least one isocyanate group and having on average at least one hydrolyzable silane group of the formula (I) —X—Si—R3sG3-s  (I) where G=identical or different hydrolyzable groups, X=organic radical, R3=alkyl, cycloalkyl, aryl, or aralkyl, it being possible for the carbon chain to be interrupted by nonadjacent oxygen, sulfur, or NRa groups, with Ra=alkyl, cycloalkyl, aryl, or aralkyl, s=0 to 2, c) at least one phosphorus- and nitrogen-containing catalyst (D) for the crosslinking of silane groups, and d) at least one catalyst (Z) for the reaction of the hydroxyl groups with the isocyanate groups, which comprises the catalyst (Z) being selected from the group of zinc and bismuth carboxylates, of aluminum, zirconium, titanium and/or boron chelates, of inorganic, tin-containing catalysts, and of mixtures thereof. The present invention further provides the coatings obtainable by this method and also the use thereof.
