  • Bark extended phenolic resin adhesive composition and process for preparing same
    Patent number: 4144205
    Abstract: A new and improved, high quality, bark-extended phenolic resin adhesive composition for bonding wood plies, particularly southern mill wood such as the southern pine, comprising the reaction product of finely ground wood bark particles treated with a caustic solution and a low molecular weight, aqueous alkaline phenol-aldehyde resin. The resin has a low degree of polymerization and is soluble in all proportions in ethanol. The resulting adhesive has a proportion by weight of total resin solids in the range of approximately 25.1% to 20.9% and a proportion of total solids in a range of approximately 40% to 40.85% based upon the total weight of the adhesive composition. The adhesive has a viscosity in a range of approximately 9,000 centipoise to 10,600 centipoise.
