Adhesives containing a resin, a kraft lignin, and a surfactant and methods for making and using same

An adhesive, comprising:

• about 20 wt % to about 40 wt % of a phenol-formaldehyde resin;
• about 1 wt % to about 10 wt % of a kraft lignin;
• about 0.05 wt % to about 1 wt % of a lignosulfonate;
• about 0.5 wt % to about 5 wt % of an alkaline compound;
• and
• about 50 wt % to about 65 wt % of water, wherein all weight percent values are based on a combined weight of the phenol-formaldehyde resin, the kraft lignin, the surfactant, the alkaline compound, and the water, wherein the adhesive has a viscosity of about 500 cP to about 4,000 cP at a temperature of about 25° C., for a period of time of at least 1 day, and wherein the period of time starts when the adhesive is initially produced.

A resinated furnish, comprising:

• a plurality of lignocellulose substrates;
• and
• an adhesive, wherein the adhesive comprises:
• about 20 wt % to about 40 wt % of an aldehyde-based resin;
• about 1 wt % to about 15 wt % of a kraft lignin;
• about 0.05 wt % to about 2 wt % of a surfactant;
• about 0.5 wt % to about 10 wt % of an alkaline compound;
• and
• about 45 wt % to about 70 wt % of water, wherein 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, and wherein the adhesive has a viscosity of about 500 cP to about 5,000 cP, at a temperature of about 25° C.
