Abstract: Crosslinkers based on alkoxysilanes and alkoxysilane mixtures containing an isocyanate group can be used as a starting component in the production of coating compositions or as paint binder component, or can be used with adhesive o sealant binders o binder components having g ups reactive toward alkoxysilane groups.

Abstract: The present invention relates to alkoxysilane-functionalized allophanates, to methods for production thereof, and to the use thereof. In particular, the alkoxysilane-functionalized allophanate includes the reaction product of A) at least one alkoxysilane group-containing monourethane A) of the formula 1 Rn(OR1)3-nSi—R2—NH—(C?O)—OR3??formula 1, 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 B) at least one diisocyanate B), in a molar ratio of A) to B) of 3:1 to 1.5:1.
