ABSTRACT:
A novel diepoxide curing agent is revealed. The curing agent comprises a mixture of an imidazole compound and a selected polyoxyalkylenepolyamine.
This curative produces an epoxy resin of low viscosity with a prolonged pot life. They find particular usefulness in filament winding and pultrusion processes where they are used to fabricate articles of considerable strength.
