Coating compositions comprising monoallophanates based on alkoxysilane alkyl isocyanates

Abstract

A coating composition that includes an allophanate-containing compound can offer improved scratch resistance. The coating composition includes A) at least one allophanate-containing compound having the formula (1): wherein R, R1-R6 are each independently identical or different hydrocarbyl radicals having 1-8 carbon atoms, which may be branched or cyclic, or else may be integrated together to form a cyclic system, and m and n are each independently 0-2, B) a binder, C) optionally, an aliphatic or cycloaliphatic polyisocyanate having an NCO functionality of at least 2, D) optionally, a catalyst, E) optionally, an auxiliary and/or additive, and, F) optionally, a solvent.
