摘要

Solid, acetone-soluble, curable adduct of a liquid polyfunctional aromatic amine having, per molecule, 3 to 6 active H atoms attached to amino N and a difunctional aromatic amine having, per molecule, 2 active H atoms attached to amino N, the adduct having a softening point between 50 deg. and 150 deg.C and an epoxy equiv. ot. between 300 and 3000. They are particularly suitable for making large castings as cure proceeds at moderate temp. without liberation of large amt. of heat, so giving stronger products. The cured products also have superior heat resistance.
