Abstract
Composition including at least one polymer containing silane groups and at least one zinc(II) complex compound of Zn(L)(Y), where k is an integer from 1-10, x is 1, 2, 3, or 4, n corresponds to of ligand L, Y is ligand having −1 charge, and L is ligand of where n is 1, 2, or 3, A is Ror polyoxyalkylene group or group of polyoxyalkylated compound optionally having one or two terminal 1,3-ketoamide groups, Rand Rare hydrogen residue or monovalent saturated or unsaturated hydrocarbon group having 1-10 carbon atoms independently of each other or jointly bivalent alkylene group having 3-6 carbon atoms; Rand Rare hydrogen residue or monovalent saturated hydrocarbon group having 1-12 carbon atoms independently of each other, hydrocarbon group optionally contains one or more heteroatoms, or jointly bivalent alkylene group having 3-6 carbon atoms, which alkylene group optionally contains one or more heteroatoms. The invention further relates to the use of the zinc(II) complex compound of the formula Zn(L)(Y)as a catalyst for the cross-linking of polymers containing silane groups by means of moisture.
