    摘要: The invention relates to moisture-curing coating compositions based on aprotic solvents, comprising (A) at least one binder having alkoxysilane groups and (B) at least one crosslinking catalyst, characterized in that said composition comprises as binder (A) at least one polyacrylate and/or poly-methacrylate which is obtainable using one or more ethylenically unsaturated monomers (a1) of the formula (I) with R=hydrogen or methyl radical, R′=hydrogen, alkyl or cycloalkyl, and R″=alkyl, cycloalkyl, aryl or aralkyl, it being possible for the carbon chain to be interrupted by nonadjacent oxygen groups, sulfur groups or groups NRa, with Ra=alkyl, cycloalkyl, aryl or aralkyl, and x=0 to 2, and as crosslinking catalyst at least one phosphorous- and nitrogen-containing catalyst (B). The present invention also provides a method of producing a multicoat finish using these coating compositions, more particularly of producing a refinish, and also to the use of this method to coat interior or exterior bodywork components or to coat components for shipbuilding and aircraft construction or to coat components for household and electrical appliances or to coat plastics moldings or films.
