Title: ADHESIVES CONTAINING A RESIN, A KRAFT LIGNIN, AND A SURFACTANT AND METHODS FOR MAKING AND USING SAME
Abstract:
Adhesives containing an aldehyde-based resin, a kraft lignin, and a surfactant and methods for making and using same are provided. In one or more embodiments, the adhesive can include an aldehyde-based resin; a kraft lignin; a surfactant; an alkaline compound; and water. The adhesive can have a viscosity of about 500 cP to about 5,000 cP, at a temperature of about 25°C. In one example, the adhesive can include about 20 wt% to about 40 wt% of the aldehyde-based resin, about 1 wt% to about 15 wt% of the kraft lignin, about 0.05 wt% to about 2 wt% of the surfactant, about 0.5 wt% to about 10 wt% of the alkaline compound, and about 45 wt% to about 70 wt% of water, where all weight percent values are based on a combined weight of the aldehyde-based resin, the kraft lignin, the surfactant, the alkaline compound, and the water.
