Zusammenfassung:	Non-aqueous coating material comprises (A) at least one crosslinker component consisting of at least one aliphatic and/or cycloaliphatic polyisocyanate having an isocyanate (NCO)-functionality of 2-6, where at least 90 mole% of the free isocyanate groups originally present in the diisocyanate or polyisocyanate having undergone reaction with at least one secondary aminosilane compound (I), (B) optionally one or more binder components, (C) 0.05-5 wt.% of at least one catalyst, (D) optionally one or more auxiliaries and/or adjuvants, and (E) optionally one or more organic solvents. Non-aqueous coating material comprises: (A) at least one crosslinker component consisting of at least one aliphatic and/or cycloaliphatic polyisocyanate having an isocyanate (NCO)-functionality of 2-6, where at least 90 mole% of the free isocyanate groups originally present in the diisocyanate or polyisocyanate having undergone reaction with at least one secondary aminosilane compound of formula (R1(NH)-X-Si(OR) 3 x-(Rx)) (I), (B) optionally one or more binder components, (C) 0.05-5 wt.% of at least one catalyst consisting of (C1) at least one organic carboxylic acid having a melting point of at least 60[deg] C and/or (C2) at least one tetraalkylammonium carboxylate, (D) optionally one or more auxiliaries and/or adjuvants, and (E) optionally one or more organic solvents. R1 : X-Si(OR) 3 x-Rx; R : alkyl, cycloalkyl, aryl or aralkyl having 1-10C, where the carbon chain is interrupted by non-adjacent O, S, or NR1a groups; R1a : alkyl, cycloalkyl, aryl or aralkyl having 1-10C; X : 1-20C-hydrocarbyl; and x : 0-2.
