SILANE-MODIFIED POLYURETHANE RESINS, A PROCESS FOR THEIR PREPARATION AND THEIR USE AS MOISTURE-CURABLE RESINS |
摘要 |
The present invention relates to moisture-curable resins having an alkoxysilane group content (calculated as Si, MW 28) of 0.2 to 4.5% by weight, based on the weight of the moisture-curable resins, and optionally containing hydroxy groups, wherein the alkoxysilane groups are incorporated as the reaction products at an NCO/OH equivalent ratio of 0.5:1.0 to 1.0:1.0 of i) a polyol having a functionality of at least 4 and an equivalent weight of at least 200 with ii) a compound containing urea, isocyanate and alkoxysilane groups corresponding to the formula I (see formula I) The present invention also relates to a process for preparing these moisture-curable resins, to coating, adhesive or sealing compositions containing these resins as the binder and to the compounds containing urea, isocyanate and alkoxysilane groups used to prepare these resins.
