Patent ID: 7867619

Claim:
A moisture-curing composition comprising a) at least one silane-functional polymer having at least two end groups of the formula (I) where R 1 is an alkyl group having 1 to 8 C atoms; R 2 is an alkyl group having 1 to 5 C atoms; a is 0, 1 or 2; and X is a divalent radical selected from the group consisting of —NH—CO—N(R 3 )—, —NH—CO—S—, —NH—CO—O—, —O—CO—NH—, —N(R 3 )—CO—NH—, and —S—CO—NH—, where R 3 is a hydrogen atom or is a linear or branched hydrocarbon radical having 1 to 20 C atoms which optionally contains cyclic fractions and which optionally has at least one functional group selected from the group consisting of alkoxysilyl, ether, sulfone, nitrile, nitro, carboxylic ester, sulfonic ester, and phosphonic ester; b) at least aminosilane having at least one primary and/or secondary amino group; c) at least one silane which is selected from the group consisting of (meth)acrylic silanes of the formula (II) and anhydridosilanes of the formula (III), where R 4 is an alkyl group having 1 to 8 C atoms; R 5 is an alkyl group having 1 to 5 C atoms; R 6 is a linear or branched, optionally cyclic, alkylene group having 2 to 20 C atoms, optionally with aromatic fractions, and optionally with heteroatoms, R 7 is a hydrogen atom or is a methyl group, R 8 is a trivalent hydrocarbon radical having 2 to 5 C atoms, and b is 0 or 1, in particular 0.
