    • The present invention is directed to polyisocyanate addition compounds which i) are substantially free from isocyanate groups and are prepared from one or more a) polyisocyanate adducts and/or b) NCO prepolymers, ii) contain urethane groups, iii) contain fluorine in an amount of 0.01 to 50% by weight, and iv) contain ethylenically unsaturated groups in an amount of 2 to 40% by weight, wherein the preceding percentages are based on the solids content of the polyisocyanate addition compounds. The fluorine is incorporated by reacting an isocyanate group with a compound containing two or more carbon atoms, one or more hydroxyl groups and one or more fluorine atoms to form urethane and optionally allophanate groups. More than 50 mole % of the groups that incorporate fluorine into the addition compounds are urethane groups. The polyisocyanate addition compounds are useful in coating compositions that are curable by free radical polymerization.
    • 本发明涉及多异氰酸酯加成化合物,其i)基本上不含异氰酸酯基团,并且由一种或多种a)多异氰酸酯加合物和/或b)NCO预聚物制备,ii)含有氨基甲酸酯基团,iii)含有一定量的氟 为0.01〜50重量%,iv)含有2〜40重量%的烯键式不饱和基团,其中前述百分数是基于多异氰酸酯加成化合物的固体含量。 通过使异氰酸酯基团与含有两个或更多个碳原子,一个或多个羟基和一个或多个氟原子的化合物反应来形成氟,以形成氨基甲酸酯和任选的脲基甲酸酯基。 将氟加入加成化合物的基团的50摩尔%以上是氨基甲酸酯基。 多异氰酸酯加成化合物可用于通过自由基聚合可固化的涂料组合物。
