Patent ID: 8293368

Claim:
A moisture-curing composition comprising: at least one silane-functional polymer A which is a polymer A1 prepared by reacting a polyurethane polymer containing isocyanate groups with an aminosilane AS1 selected from the group consisting of products of a Michael-like addition reaction of 3-aminopropyldiethoxymethylsilane, 3-aminopropyltriethoxysilane, 3-aminopropyldimethoxymethylsilane, and 3-aminopropyltrimethoxysilane with Michael acceptors selected from the group consisting of acrylonitrile, acrylic and methacrylic esters, maleic and fumaric diesters, citraconic diesters, and itaconic diesters, at least one aminosilane AS2, and at least one silane of formula (I) in an amount of 0.6 -5.0 parts by weight, based on 100 parts by weight of polymer A, where: R 1 is an alkyl group having from 1 to 8 C atoms, R 2 is an alkyl group having 1 to 5 C atoms, and X is a substituent attached via a heteroatom, and wherein said polyurethane polymer is obtained through the reaction of at least one polyisocyanate and at least one polyol.
