<p>The present invention relates to moisture-curable compounds which a) have an isocyanate group content (calculated as NCO, MW 42) of 2 30% by weight and an alkoxysilane group content (calculated as Si, MW 28) of 0.2 to 4.5% by weight, b) optionally contain repeating ethylene oxide units and c) have an equivalent ratio of isocyanate groups to alkoxy groups of 1.0:0.05 to 1.0:2.5, wherein the preceding percentages are based on the weight of the moisture-curable compounds and wherein the alkoxysilane groups are incorporated as the reaction products of i) a polyisocyanate component having a minimum average functionality of 2.0 and containing at least 50% by weight of polyisocyanate adducts, provided that when the moisture-curable compounds contain ethylene oxide units, the polyisocyanate component has a minimum average functionality of 2.4, and ii) amino compounds containing alkoxysilane groups and corresponding to formula I <CHEM> The present invention also relates to coating, adhesive or sealing compositions containing these moisture-curable compounds as the binder.</p> |
