USE AS CATALYST FOR FORMING URETHANES, OF FLUORINATED AND TRIVALENT METAL ACID SALTS, COMPOSITION CONTAINING SAME AND METHODS USING SAME

摘要

The present invention relates to a novel catalyst for forming a polyurethane. The catalyst is characterized by the formula:; [Formula I]; MY _3-q [Z] _q; [In the formula, Z is a radical corresponding to an anion of a superacid, it haemmaet constant thereof is more than 13, advantageously more than 13;; M is a metal that, preferably 3 illustrates what is known as forming a Lewis acid;; Y is an anion or anionic functional group 1;; q is an integer advantageously chosen from 1 to 3, inclusive.; The present invention is applicable to paint.
