Retrospective Theses and Dissertations

Recent research attention has focused on soybean-based adhesives because of increased phenolic resin prices and adhesive demand. This study was conducted to investigate the adhesive properties of crosslinked soy flour and/or soy hydrolyzate with phenol-formaldehyde (PF) resins for use in structural panels. Neutral phenolic soy (NPS) and alkaline phenolic soy (APS) resins were prepared and used to bond southern pine plywood. Adhesive bond quality of the soybean-based phenolic resins was evaluated by glueline shear test following the procedure detailed in Product Standard PS 1-95 for construction and industrial plywood. Within the range of variable levels investigated, the following conditions ...
