摘要：
Disclosed is a coating composition based on aprotic solvents and comprising at least one 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 (I) with G=identical or different hydrolyzable groups, R′=hydrogen, alkyl or cycloalkyl, X=organic radical, R″=alkyl, cycloalkyl, aryl or aralkyl, x=0 to 2, and characterized in that (i) the compound (B) containing isocyanate groups and silane groups comprises uretdione groups, and (ii) the compound (B) has been prepared from a linear aliphatic diisocyanate. The present invention additionally provides multistage coating methods using these coating compositions, and the use of the coating compositions as clearcoat, and application of the coating method for automotive refinish and/or for the coating of plastics substrates.
