Abstract:
A method of increasing the glass transition point of a cured epoxy comprising a bisphenol A diglycidyl ether and a polyetheramine includes the step of including 1,8-diamino-p-menthane as an additional hardener for curing the epoxy. An epoxy formulation includes bisphenol A diglycidyl ether and a hardener including a polyetheramine and 1,8-diamino-p-menthane.
