  • Thermosetting adhesive resins
    Patent number: 4524164
    Abstract: A thermosetting adhesive resin suitable for binding lignocellulosic materials to form products, such as plywood or particle board, is prepared by heating an aqueous sugar or starch solution in the presence of an inorganic acid or its ammonium salt and a metal ion catalyst to obtain a partially polymerized resin which is reacted with an organic acid anhydride just prior to application to the lignocellulosis materials. The adhesive formula contains no formaldehyde and the preferred aqueous solutions are whey or whey byproduct concentrates.
