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:
The present disclosure provides formulations that provide fire resistance when applied as a coating to a surface (e.g., the surface of a wood product). The compositions include an isocyanate, a brominated compound that is reactive with the isocyanate to form a polyurethane, an intumescent component, and a fire-retardant synergist. Wood products treated with the composition, as well as methods for applying the composition to a surface, are also provided.
摘要:
Wood-based composites, compositions for use in wood-based composites, and associated systems and methods are provided herein. Certain compositions include a mixture of alpha olefins and esters and demonstrate unique water repellant properties. The compositions may be incorporated in wood-based composites in place of traditional petroleum-based slack waxes.

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:
