ABSTRACT:
A moisture-curable, alkoxysilane-functional polyether urethanes containinga) 20 to 90% by weight, of a polyether urethane containing two or more reactive silane groups and one or more polyether segments, where the polyether segments have a number average molecular weight (Mn) of at least 3000 and a degree of unsaturation of less than 0.04 milliequivalents/g, and the sum of Mn of all of the polyether segments per molecule averages 6000 to 20,000, and the reactive silane groups are incorporated by the reaction of an isocyanate group with a compound of formulain-line-formulae description="In-line Formulae" end="lead"?H2N—Y—Si—(X)3 (I)in-line-formulae description="In-line Formulae" end="tail"?b) 10 to 80% by weight, of a polyether urethane containing one reactive silane group and one or more polyether segments having Mn of 1000 to 15,000, where the reactive silane groups are incorporated by the reaction of an isocyanate group with a compound of formula
