Investigation of the Wood/Phenol-Formaldehyde Adhesive Interphase Morphology
… the morphology of the wood/ Phenol-Formaldehyde (PF) adhesive interphase using yellow-poplar. In this case, morphology refers to the scale or dimension of adhesive penetration into wood. The objective is to develop methods for revealing ever smaller levels of wood/resin morphology. Dynamic …

Comparison of soy-flour hydrolysates for wood adhesive systems
… Soy hydrolysate and phenol-formaldehyde (PF) resin blends made from four types of enzymatic hydolysates were tested for the time required for polymerization, water-resistance, and their performance in medium-density fiberboard applications. Results show that for all of the aforementioned …

Using fungicides or combinations of fungicides to provide mold and decay fungal protection to OSB
… The compatibility of the fungicide on the resin curing was studied by measuring change in the resin gelation and viscosity. After these screening experiments were completed, large size boards were prepared and mechanical and decay resistance properties were examined. It was found that mold …

Effect of Cellulose Nanocrystals on the Rheology, Curing Behavior, and Fracture Performance of Phenol-Formaldehyde Resol Resin
… and performance of phenol–formaldehyde (PF) adhesive resin. The steady-state viscosity of a commercial PF resol resin and three CNC–resin mixtures, containing 1–3 wt % CNCs, based on solids content, was measured with a rheometer as a function of shear rate. The viscosity of the PF resin …

Production and separation of medically relevant terbium-161 for radiopharmaceutical applications and recycling of target materials
… HPLC method followed by sequential LN and RE/PF resin columns achieved overall recovery yields of 55 ± 7%. For larger-scale processing, an extraction chromatography method using TK212, TK211, TK221, and A-8 resins was implemented, enabling purification from targets containing up to 201 mg Gd …

Fundamental properties of borate-modified oriented strandboard manufactured from southern wood species
… zinc borate (ZB) and calcium borate (CB) on resin gel time, strength, swelling, leaching, termite, decay, and mold resistance properties of oriented strandboard (OSB). It was found that gel time of phenol formaldehyde (PF) resin decreased with increased amount of ZB, indicating interaction …
