发明名称 | Moisture-curing coating compositions comprising aprotic solvents and binders having alkoxysilane groups and method of forming a multicoat finish therewith | ||
摘要 | Disclosed is a moisture-curing coating composition based on aprotic solvents comprising a binder with a polyacrylate or polymethacrylate obtained using monomer (I); and a phosphorous- and nitrogen-containing catalyst. Also disclosed is a method of producing a multicoat finish using these coating compositions 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. | ||

主权项 | 1. A moisture-curing coating composition comprising aprotic solvents, and 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 polymethacrylate which is obtained by polymerizing 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, the carbon chain thereof optionally being interrupted by nonadjacent oxygen groups, sulfur groups or groups NRa, with Ra=alkyl, cycloalkyl, aryl or aralkyl, and x=0 to 2, and further ethylenically unsaturated monomers consisting of ethylenically unsaturated monomers without active hydrogen and as crosslinking catalyst at least one phosphorous- and nitrogen-containing catalyst (B). | ||
