MOISTURE-CURABLE COMPOUNDS CONTAINING ISOCYANATE AND ALKOXYSILANE GROUPS

摘要

The present invention relates to moisture-curable compounds which a) have an isocyanate group content (calculated as NCO, MW 42) of 0.2 to 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, which are bound to Si, of 1.0:0.05 to 1.0:1.4, 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 polyisocyanates with amino compounds corresponding to formula I (see formula I) The present invention also relates to coating, adhesive or sealing compositions containing these moisture-curable compounds as the binder.
