Zusammenfassung:Die vorliegende Erfindung betrifft Alkoxysilan-funktionalisierte Allophanat-haltige Beschichtungsmittel, ein Verfahren zur ihrer Herstellung, und ihre Verwendung. where R, R1, R2 and R3 are each independently hydrocarbyl radicals having 1-8 carbon atoms, which may be linear, branched or cyclic, or else may be integrated together to form a cyclic system, and n is 0-2, and ii) at least one diisocyanate ii), in a molar ratio of i) to ii) of from 3:1 to 1.5:1, preferably from 2.5:1 to 1.8:1, particularly preferably 2:1; b) 1-90 wt % of at least one other binder component, different from a), preferably a hydroxyl-containing or amino-containing binder component, c) 0-50 wt % of at least one aromatic, aliphatic or cycloaliphatic polyisocyanate having an NCO functionality of at least 2, preferably 2.8 to 6, d) 0-5 wt % of at least one catalyst, where components a)-d) add up to 100 wt %.
