    • The present invention relates to low viscosity, ethylenically-unsaturated polyurethanes which are substantially free from isocyanate groups, are liquid at 25° C., have a total content of ethylenically unsaturated groups (calculated as C═C, MW 24) of 1 to 12% by weight and contain the reaction product of A) 4-isocyanatomethyl-1,8-octamethylene diisocyanate (NTI) with B) a hydroxyl component comprising i) 5 to 100 hydroxyl equivalent % of one or more hydroxy functional lactone ester (meth)acrylates having a number average molecular weight of about 200 to 1000, ii) up to 95 hydroxyl equivalent % of a monohydroxy-functional, ethylenically unsaturated compound other than B-i), and iii) up to 20 hydroxyl equivalent % of a saturated hydroxyl compound or an unsaturated hydroxyl compound other than B-i) or B-ii), wherein i) the hydroxyl equivalent %'s of components B-i), B-ii) and B-iii) add up to 100%, based on the total weights of components B-i), B-ii) and B-iii) and ii) the NCO:OH equivalent ratio of component A) to component B) is 1.10:1 to 1:1.10. The present invention also relates to a one-component coating composition containing these ethylenically unsaturated polyurethanes.
    • 本发明涉及基本上不含异氰酸酯基团的低粘度烯键式不饱和聚氨酯,在25℃下为液体,烯属不饱和基团的总含量(以CC,MW 24计算)为1〜12%,含量为1〜12% 含有A)4-异氰酸甲酯基-1,8-八亚甲基二异氰酸酯(NTI)与B)羟基组分的反应产物,其包含i)5至100个羟基当量%的一种或多种羟基官能的内酯酯(甲基)丙烯酸酯,其具有 数均分子量为约200至1000,ii)除Bi之外的至多95羟基当量%的单羟基官能的烯键式不饱和化合物),和iii)饱和羟基化合物或不饱和羟基化合物的至多20羟基当量% 除了Bi)或B-ii)之外的羟基化合物,其中i)组分Bi),B-ii)和B-iii的羟基当量%)基于组分Bi)的总重量加起来为100% ,B-ii)和B-iii)和ii)NCO:OH等同物 组分A)与组分B)的比例为1.10:1-1:1.10。 本发明还涉及含有这些烯属不饱和聚氨酯的单组分涂料组合物。
