Abstract:Soy whey, soy molasses, defatted soy flour, soy protein concentrate, soy protein isolate, and spent soy hulls were screened as 10% replacement of resin binder polymer in extended glues on 7.5% m.c. veneer. None of the glues matched control, but hulls performed best. Flour, concentrate, and isolate showed some adhesive ability. Whey and molasses performed like fillers. Molasses, flour, concentrate, and isolate, were synthesized into resins as 10% phenol replacement. Resins were similar to controls except for thixotropy and reduced formaldehyde of molasses resin. In bonding moist veneers, molasses resins accelerated cure, while maintaining full cure performance. Isolate accelerated wet strength development. A series of phenol replacement molasses-modified resins was prepared to 50%. Resins had increasing solids and decreasing free formaldehyde to 40% SM, with peculiar thixotropyldose response. Molasses resins showed cure acceleration over 10-30% range, but full cure bonding fell at 30%.
