Abstract
Abstract Acurable resin composition comprising an epoxy resin, a hardener and an epoxy compound-dialkyl-amine adduct as a latent hardener. The composition has good storage stability at ambient temperatures and is rapidly heat-curable, and is usable as or in adhesives, paints, molding materials, and casting materials.
