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. |
