ABSTRACT:
A curing agent for epoxy resins is prepared from an amine and an epoxy, as well as subsequent modification by a polyisocyanate compound, in such a manner that the curing agent is in the form of small spherical particles. The particles can be as small as 0.1 microns. This curing agent can be easily dispersed in curing agent masterbatches and curable compositions with minimal effect on their storage stability. The resulting curable compositions have a wide range of applications, including automobile and electronic adhesives.
