    • Disclosed is an ungelled urethane resin composition containing a urethane compound having in a molecule thereof at least one group containing a silicon atom selected from: ##STR1## wherein Q represents the residue from a urethane polyol; eachR which may be the same or different, represents hydrogen or a C.sub.1 -C.sub.10 group joined to Si through an Si-C linkage; andY represents an easily hydrolyzable group.The urethane resin composition contains an amount of easily hydrolyzable Y moieties such that the ratio of the number of grams of the ungelled urethane resin composition to equivalents of easily hydrolyzable Y moieties in the ungelled urethane resin composition is in a range of from 40 to 667. Preferred urethane resin compositions can be cured in the presence of atmospheric moisture and a suitable catalyst at a temperature of less than or equal to 121 degrees Celsius within 3 hours.Disclosed is a method for producing the ungelled urethane resin composition.Also disclosed is a nonaqueous composition, particularly a nonaqueous coating composition, containing an ungelled urethane resin composition. Preferred coating compositions containing an ungelled urethane resin composition can be cured in the presence of atmospheric moisture and a suitable catalyst at a temperature of less than or equal to 121 degrees Celsius.
    • 本发明公开了一种非凝胶型聚氨酯树脂组合物,其含有在分子中具有至少一个含有选自以下的硅原子的氨基甲酸酯化合物:其中Q表示氨基甲酸酯多元醇的残基; 每个R可以相同或不同,表示氢或通过Si-C键与Si连接的C1-C10基团; Y代表易水解基团。 聚氨酯树脂组合物含有一定量的易水解的Y部分,使非凝胶聚氨酯树脂组合物的克数与易凝胶化聚氨酯树脂组合物中容易水解的Y部分的当量之比在40至667的范围内。 优选的聚氨酯树脂组合物可在大气水分和合适的催化剂存在下在3小时内在小于或等于121℃的温度下固化。 公开了非凝胶化聚氨酯树脂组合物的制造方法。 还公开了含有非凝胶化聚氨酯树脂组合物的非水性组合物,特别是非水性涂料组合物。 含有未胶凝的聚氨酯树脂组合物的优选涂料组合物可在大气湿度和合适的催化剂存在下在小于或等于121摄氏度的温度下固化。
