Abstract

A liquid adduct is prepared from the reaction of an amine, a polyepoxide compound with a functionality greater than 2, and, optionally, a diglycidyl ether of bisphenol A and/or the hydrogenated equivalent thereof, an accelerator or a suitable solvent; said reaction continuing until no active epoxy groups are available. The adducts are useful as curing agents for epoxy resins in both room temperature and heat cured applications to produce protective coatings of superior properties.
