摘要： A composite wood product in accordance with a particular embodiment of the present technology includes a composite substrate and a sealant disposed within a surface portion of the substrate. The substrate includes wood and a binder. The sealant includes photoresponsive molecules present within the surface portion of the substrate at an average concentration greater than 1000 parts per million. In response to a 120-day exposure at 7 inches separation distance to a UV lamp with a UVA (315-400 nm) output of 13.6 W and a UVB (280-315 nm) output of 3.0 W, a CIELab b* value of the substrate decreases by a first amount, a CIELab b* value of the sealant increases by a second amount, and a CIELab b* value of the overall wood product decreases by an amount less than the first amount, increases by an amount less than the second amount, or is unchanged.

摘要： Disclosed herein are adhesives, wood-based composites incorporating the adhesives, and methods of forming wood-based composites using the adhesives. In some embodiments, an adhesive emulsion includes a continuous phase having an aqueous, alkaline solution that includes a melamine/urea/formaldehyde (“MUF”) resin, and a dispersed phase that includes a multifunctional aromatic isocyanate component. The solution including the MUF resin has a percent solids content of about 1.0% to about 90.0%, and the MUF resin and the multifunctional aromatic isocyanate component are present in a ratio of about 92:8 to about 40:60 on a solids mass basis. Wood-based composites formed using the adhesives demonstrate an optimal combination of characteristics desirable to the wood products industry.

摘要： Wood-based composites, and methods for their manufacture, are provided. The composites include oriented wooden strands and cured bonding resin connecting adjacent strands. The composites are relatively low-density, having an average dry density of the wooden composites of about 15-28 pounds per cubic foot (pcf). The unique composition of the composites provide improved structural and insulating (thermal and acoustic) properties when compared to traditional engineered wood products (e.g., oriented strandboard).
