Abstract
  • Abstract: 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.
