Resin systems and methods for making and using same are provided. The resin system can include a first aqueous resin comprising at least two polymerized monomers and a second aqueous resin comprising at least two polymerized monomers. The first aqueous resin can be present in an amount of about 5 wt % to about 95 wt %, based on the total weight the resin system. The second aqueous resin can be present in an amount of about 5 wt % to about 95 wt %, based on the total weight the resin system. The at least two polymerized monomers of the first and second aqueous resins can be the same monomers.

Powdered adhesives for making lignocellulosic composite products and methods for making same. The powdered adhesive can include a powdered phenol-aldehyde resin and a powdered kraft lignin. The powdered kraft lignin can contain less than 3 wt % of ash, as measured according to ASTM D2584-11. The powdered adhesive can contain less than 10 wt % of water.

Methods for making phenolic resins modified with one or more monosaccharides and methods for making composite products therewith are provided. In at least one specific embodiment, a method for making a composite product can include contacting a plurality of cellulosic sheets with a resin composition that includes a phenolic resin and a monosaccharide. The resin composition can include about 0.5 wt % to about 30 wt % of the monosaccharide, based on a combined weight of the phenolic resin and the monosaccharide. The method can also include at least partially curing the resin composition to produce a composite product.
