Three novel curing agents (I, II, and III) were synthesized from epichlorohydrin and ammonium hydroxide. The combinations of soy flour (SF) with one of the curing agents (SF-I, SF-II, and SF-III) were investigated as adhesives for making interior plywood. Water resistance tests showed that plywood panels bonded with SF-I and SF-III adhesives met the requirements of interior plywood, whereas those bonded with SF-II did not. The modulus of rupture, modulus of elasticity, and internal bond strength of particleboard panels bonded with the SF-II adhesive all exceeded the corresponding minimum industrial requirements for M-2 grade particleboard.
