摘要

PROBLEM TO BE SOLVED: To provide an epoxy resin curative which is used in water-base coating materials, adhesives, sizing agents, etc., is excellent in emulsion stability and water resistance, and has a self-emulsifying function and an epoxy resin compsn. contg. the same. ;SOLUTION: This curative, having a self-emulsifying function, is obtd. by reacting (A) an epoxy compd. with (B) a polyamine and is characterized in that it has oxazolidone rings in the molecule and is obtd. by reacting isocyanate groups of (a) an isocyanate-terminated compd. formed from a polyethylene glycol compd. and a polyisocyanate compd. with epoxy groups of (b) an epoxy resin. The epoxy resin compsn. is prepd. by compounding an epoxy resin with the curative.;COPYRIGHT: (C)1999,JPO
