摘要： The present invention relates to coating materials based on aprotic solvents, comprising at least one oligomeric and/or polymeric hydroxyl-containing compound (A) and at least one compound (B) having isocyanate groups and having at least one silane group of the formula (I): -X-Si-R"xG3-x where G = identical or different hydrolysable groups, more particularly G = alkoxy group (OR'), R' = hydrogen, alkyl or cycloalkyl, it being possible for the carbon chain to be interrupted by non-adjacent oxygen, sulphur or NRa groups, where Ra = alkyl, cycloalkyl, aryl or aralkyl, X = organic radical, more particularly linear and/or branched alkylene or cycloalkylene radical having 1 to 20 carbon atoms, R" = alkyl, cycloalkyl, aryl or aralkyl, it being possible for the carbon chain to be interrupted by non-adjacent oxygen, sulphur or NRa groups, where Ra = alkyl, cycloalkyl, aryl or aralkyl, x = 0 to 2, characterized in that (i) the compound (B) containing isocyanate groups and silane groups has uretdione groups, and (ii) the compound (B) has been prepared from a linear aliphatic diisocyanate. The present invention further provides multi-stage coating methods using these coating materials, and also the use of the coating materials as clearcoat material, and application of the coating method for automotive refinishing and/or for the coating of plastics substrates.
