Abstract:
1. A single-component, moisture-curing composition, comprising: a) at least one polyurethane polymer PUP formed from a reaction of at least one aromatic or aliphatic polyisocyanate and at least one polyol, wherein a content of free isocyanate groups of the polyurethane polymer PUP is 0.5 to 15% by weight; b) at least one aldimine A, formed from a condensation reaction between at least one polyamine B with at least two primary aliphatic amino groups, and at least one aldehyde selected from the group consisting of aldehyde ALD2 of formula (V b) and aldehyde ALD3 of Formula (V c): wherein R independently of one another in each case stands for a monovalent hydrocarbon radical with 1 to 12 C atoms, or together stand for a divalent hydrocarbon radical with 4 to 12 C atoms, which is part of an optionally substituted, carbocyclic ring with 5 to 8 C atoms; R R R c) at least one organoalkoxysilane OS selected from the group consisting of N-(trimethoxysilylmethyl)-O-methyl-carbamate, N-(dimethoxymethylsilylmethyl)-O-methyl-carbamate, (methacrvloxymethyl)trimethoxysilane, (methacryloxymethyl)triethoxysilane, an α-aminosilane, an α-silane-functional polymer, and a combination thereof; d) at least one organic Brønsted acid S; provided that in the composition,
