Beschreibung
Zusammenfassung:	An epoxy curing agent is disclosed that can be obtained by reacting at least one carboxylic acid with at least one polyamine. The disclosed curing agent can be obtained by preparing an amidoamine with about 0.15 to about 0.30 molar excess of carboxylic acid. Cette invention concerne un agent durcisseur époxy qui peut être obtenu par réaction d'au moins un acide carboxylique avec au moins une polyamine. L'agent durcisseur décrit peut être obtenu par préparation d'une amidoamine utilisant un excès molaire d'acide carboxylique d'environ 0,15 à environ 0,30.
