AB  - Soy-based adhesives inherently possess low water resistance and brittleness, 
      which limit their application on plywood fabrication. This investigation involves 
      using a long chain cross-linker, neopentyl glycol diglycidyl ether (NGDE), to 
      produce an intrinsic toughening effect to reduce the brittleness and improve the 
      water resistance of a soybean meal(-)based adhesive. The solids content, viscosity, 
      functional groups, fracture surface micrographs, and thermal stability of the 
      adhesives were measured. Three-layer plywood was fabricated using the resultant 
      adhesive, and the tensile shear strength of the plywood was measured. All 
      adhesive properties were compared with a soybean 
      meal/polyamidoamine-epichlorohydrin (PAE) adhesive and commercial melamine urea 
      formaldehyde resin. The results showed that adding 6 g NGDE improved the water 
      resistance of the soybean meal-based adhesive by 12.5%. This improvement is 
      attributed to the following reasons: (1) a dense cross-linked network is formed 
      by the chemical reaction between NGDE and protein molecules; (2) the toughness of 
      the adhesive increases and a smooth and homogeneous fracture surface is created, 
      which effectively prevents moisture intrusion; (3) the addition of NGDE increases 
      the thermostability of the cured adhesive. The tensile shear strength of the 
      plywood bonded with the soybean meal-based adhesive with 6 g NGDE was 286.2% 
      higher than that without NGDE and attained 1.12 MPa, which was attributed to the 
      reduction in the adhesive's viscosity, and the improvement in the water 
      resistance and toughness of the adhesive. The tensile shear strength of the 
      plywood bonded with 6 g NGDE was 19.1% higher than that with 6 g PAE and was 
      similar to the MUF resin, which validated the novel adhesive being suitable for 
      use as an industrial plywood adhesive.
