    摘要: A lignocellulosic composite article includes a plurality of lignocellulosic pieces and an adhesive system disposed on the plurality of lignocellulosic pieces for bonding the plurality of lignocellulosic pieces. The adhesive system includes a binder component and a compatibilizer component. An example of a suitable binder component is an isocyanate component, e.g. a diphenylmethane diisocyanate (MDI), a polymeric diphenylmethane diisocyanate (pMDI), and combinations thereof. The compatibilizer component includes a trialkyl phosphate. The compatibilizer component is utilized in an amount of at least about 0.5 parts by weight based on 100 parts by weight of the binder component. The compatibilizer component is useful for reducing the amount of press time required during manufacture of the composite article. The adhesive system can include additional components, such as an isocyanate-reactive component. The composite article may be various lignocellulosic composites, such as oriented strand board (OSB), particleboard (PB), fiberboard (e.g. medium density fiberboard; MDF), etc.

    摘要: Included are polyurethaneurea compositions include polyurethaneurea aqueous dispersions. The dispersions may be prepared with solvent or in the absence of any added solvent. Films and other shaped articles may be prepared from the dispersions by a casting a drying method and optionally included with a substrate including paper, fabric or garments. The films exhibit a reduced discoloring or yellowing upon exposure to atmosphere, heat, and UV.
