Abstract
PURPOSE: To obtain a cured epoxy product being rich in flexibility and elongation and having excellent adhesive strength, water resistance and chemical resistance, by employing, as a curing agent for epoxy resins, a mono-or polyamideamine prepared from a mixture of three different amines having a hexamethylene group and a carboxylic acid.
CONSTITUTION: A carboxylic acid such as a polymerized fatty acid or an (un)saturated fatty acid is added to (D) an amine mixture which contains (A) bishexamethylenetriamine, (B) N-ethylhexamethylenediamine and (C) hexamethylenediamine in amounts of 20W80% of (A), 10W70% of (B) and 1W30% of (C), based on the total weight of (A), (B) and (C), respectively, and having a total content of the three amines, of at least 20wt%, based on the amine mixture. The resulting mixture is reacted, with heating under N2 stream. The reaction product is employed as a curing agent for epoxy resins. In order to further improve the water resistance and elongation, the total content of (A), (B) and (C) in (D) of 50W 100wt% is chosen.
