Abstract
PURPOSE: To prepare a curing agent for epoxy resins capable of cured articles having excellent flexibility and toughness, comprising an oligomer of diethanolamine having a specific amine value as a main component.
CONSTITUTION: A curing agent consisting mainly of an oligmer of diethanolamine having an amine value of 500W750, which is a high boiling compound obtained as the distillation residue formed as a by-product in the preparation of tetrahydro-1,4- oxazine. As for the oligomer, compounds of formulas I, II, III, IV, and V may be cited. 15W70, preferably 30W50 parts by weight of the curing agent is used on the basis of 100 parts by weight of an epoxy resin having an epoxy equivalent of 180W 200.
