Patent ID: 8592517

Claim:
A curable composition comprising a) at least one polyether and/or at least one polyacrylic acid ester having at least one terminal group of the general formula (I) -A n -R—SiXYZ (I), in which A is a divalent linking group, R is a divalent hydrocarbon residue having 1-12 C atoms optionally containing a heteroatom, and X, Y, Z are, independently of one another, C 1 -C 8 alkyl, C 1 -C 8 alkoxy or C 1 -C 8 acyloxy residues, at least one of the residues being a C 1 -C 8 alkoxy or C 1 -C 8 acyloxy group, and n is 0 or 1; and b) at least one organotin compound, c) at least one compound which is free from tin and silicon atoms and has at least two functions that are each selected from: carboxy groups, carbonyl groups, hydroxy groups and nitrogen atoms which are part of a ring system that is aromatic in nature, wherein component c) comprises at least one N-heteroaromatic compound or α-hydroxycarboxylic acid, wherein the N-heteroaromatic compound is selected from 8-hydroxyquinolines, 2-hydroxyquinolines, 7-hydroxy-3H-indoles, 8-hydroxyquinoxalines, 8-hydroxyquinazolines, 8-hydroxycinnolines, 4-hydroxyphenanthridines, 4-hydroxyacridines and 1-hydroxyphenazines, each optionally comprising further substituents and the α-hydroxycarboxylic acid is lactic acid.
