An amine hardener for epoxy resins which comprises an amine adduct (A) and a low-molecular amine compound (B) as major components, wherein the molecular weight distribution of the amine adduct (A), which is defined by the ratio of the weight-average molecular weight to the number-average molecular weight, is 3 or lower and the low-molecular amine compound (B) is contained in an amount of 0.001 to 1 part by mass per 100 parts by mass of the amine adduct (A).

Un durcisseur amine pour les résines d'époxy composé d'un adduct amine (A) et d'un composé d'amine faiblement moléculaire (B) comme composants principaux, dans lesquels la distribution du poids moléculaire de l'adduct amine (A), qui est définie par le ratio du poids moléculaire moyen en poids sur le poids moléculaire moyen en nombre est de 3 ou moins et le composé amine faiblement moléculaire (B) est contenu pour une quantité de 0,001 à 1 part par masse par 100 parts par masse de l'adduct amine (A).
