ABSTRACT:
Useful as catalysts for the reaction of a polyisocyanate or a partially blocked polyisocyanate with a hydroxy-containing compound are organotin compositions obtained by reacting a diorganotin oxide of the formula R.sub.2 SnO of a diorganotin dichloride of the formula R.sub.2 SnCl.sub.2 with a compound of the formula HS--CH.sub.2 CH(OH)CH.sub.2 XH where R is a C.sub.1 -C.sub.8 alkyl or an aryl group and X is --O-- or --S--.
Also disclosed are cationic electrodepositable (CED) compositions containing such catalysts.
