ABSTRACT:
Epoxy resins having acceptable pot lives, degrees of reactivity, and physical properties are obtained by the use of curing agent compositions which comprise about 99.6-90% by weight of a hindered aromatic diamine, such as diethyltoluenediamine, and about 0.4-10% by weight of an accelerator complex of boron trifluoride and a cycloaliphatic diamine, such as isophoronediamine.
