Abstract: An organic slurry for use in wood-based composites is described herein. In one aspect, the organic slurry may include water, a lignin material insoluble in the water, such as dewatered kraft lignin, and a defoamer. During manufacturing, the water, lignin material and defoamer may be combined and mixed together in a vessel to produce the organic slurry. In one aspect, the defoamer may include a water-based defoamer, a silicone-based defoamer, a silicone-free defoamer, an oil-based defoamer, a polymer-based defoamer, or mixtures thereof. The organic slurry may have a pH less than neutral.

Abstract: A wax-extender emulsion including a plurality of wax-extender complex particles suspended in water is described. A wax-extender complex includes a wax component, an organic extender component and a surfactant that stabilizes the wax component and the organic extender component collectively to form the wax-extender complex. The wax-extender emulsion comprises from 2 wt % to 30 wt % organic extender. During manufacturing, the organic extender and wax component are emulsified and homogenized together to produce the wax-extender emulsion. The wax-extender emulsion can be co-applied as a mixture with adhesive resin during wood-based composite manufacturing.

Abstract: A polymeric composition for restoring a previously formed spike hole in a wood railroad tie is described. The polymeric composition comprises a resin comprising a chain extender in a concentration of at least about 10 wt % and at least one polyol, and at least one isocyanate-containing compound. The chain extender may be diethylene glycol. The composition may also include a moisture control additive in a concentration of at least 5 wt % of the resin.

Abstract: An adhesive mixture comprising an organic slurry dispersion for use in the manufacture of wood-based composites is described herein. The adhesive mixture includes an adhesive resin; water; one or more fillers, and an organic slurry dispersion. The organic slurry dispersion includes water; a natural biopolymer insoluble in the water, the natural biopolymer comprising lignocelluloses, lignocellulosic agricultural residue, lignin materials, lignin derivatives or mixtures thereof; and a defoamer. During manufacturing, the components of the organic slurry dispersion are combined and mixed by imparting a high degree of shear and mixing. The adhesive mixture may be applied to wood material for use in manufacturing a wood-based composite product.
