ABSTRACT:
A process for the accelerated cure of an epoxy resin is disclosed. The resulting epoxy resin may be used in protective coatings, adhesives, seamless and terrazo flooring and caulking and sealing compositions. The resulting resin is also useful, for example, in casting, potting, in escapulating, grouting and patching. The process involves mixing an epoxy resin of the polyhydric phenol, polyglycidyl ether type with a curing agent comprising the reaction product of an epoxy resin with an excess of an aminoalkylene derivative of a polyoxyalkylenepolyamine.
