Patent ID: 8679589

Claim:
A coating composition comprising (a) at least one hydroxyl-containing compound (A), (b) at least one compound (B) having free and/or blocked isocyanate groups, and (c) at least one catalyst (C) for the crosslinking of silane groups, wherein the at least one catalyst (C) is a substituted phosphonic diester, a phosphonic diester, a substituted phosphoric monoester or a phosphoric diester, (d) a water scavenger constituent (D) comprising trialkyl orthoformate, wherein one or more constituents of the coating composition contain between 2.5 and 97.5 mol %, based on the entirety of structural units (II) and (III), of at least one structural unit of the formula (II) —N(X—SiR″ x (OR′) 3-x ) n (X′—SiR″ y (OR′) 3-y ) m (II) where R′=hydrogen, alkyl or cycloalkyl, the carbon chain being interrupted or not interrupted by nonadjacent oxygen, sulfur or NRa groups, with Ra=alkyl, cycloalkyl, aryl or aralkyl, X, X′=linear and/or branched alkylene or cycloalkylene radical having 1 to 20 carbon atoms, R″=alkyl, cycloalkyl, aryl or aralkyl, the carbon chain being interrupted or not interrupted by nonadjacent oxygen, sulfur or NRa groups, with Ra=alkyl, cycloalkyl, aryl or aralkyl, n=0 to 2, m=0 to 2, m+n=2, and x and y=0 to 2, and between 2.5 and 97.5 mol %, based on the entirety of structural units (II) and (III), of at least one structural unit of the formula (III) —Z—(X—SiR″ x (OR′) 3-x ) (III), where Z=—NH—, —NR—, —O—, with R=alkyl, cycloalkyl, aryl or aralkyl, the carbon chain being interrupted or not interrupted by nonadjacent oxygen, sulfur or NRa groups, with Ra=alkyl, cycloalkyl, aryl or aralkyl, x=0 to 2, and X, R′, and R″ being as defined for formula (II).
