Moisture-curable compositions containing polyisocyanates and polyacrylates having alkoxysilane groups
摘要：
The present invention relates to moisture-curable compositions containing a mixture of a) a polyisocyanate and b) a polyacrylate resin which has an alkoxysilane group content (calculated as Si, MW 28) of 0.2 to 4.5% by weight, based on the weight of the polyacrylate resin, and contains less than 0.2% by weight of hydroxy groups, based on the weight of the polyacrylate resin, wherein components a) and b) are present in amounts sufficient to provide an equivalent ratio of isocyanate groups to alkoxy groups, which are bound to Si, of 1.0:0.05 to 1.0:2.5. The present invention also relates to coatings, sealants and adhesives prepared from these compositions.
摘要（中）：

本发明涉及可湿固化的组合物，其含有下列混合物：a）多异氰酸酯和b）聚丙烯酸酯树脂的混合物，所述混合物具有烷基硅烷基含量（以Si计，MW 28计）为0.2-4.5重量％，基于聚丙烯酸酯的重量 树脂，并且基于聚丙烯酸酯树脂的重量，含有小于0.2重量％的羟基，其中组分a）和b）以足以提供异氰酸酯基团与烷氧基的当量比结合的量存在，其结合 至Si，为1.0:0.05至1.0:2.5。本发明还涉及由这些组合物制备的涂料，密封剂和粘合剂。
