Abstract
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 system 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 novel accelerator-hardener which is a condensation product of phenol, formaldehyde and an aminoalkylene derivative of a polyoxyalkylenepolyamine.
