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 comprises a binder component and an additive component. The binder component comprises a diphenylmethane diisocyanate (MDI), a polymeric diphenylmethane diisocyanate (pMDI), and combinations thereof. The additive component comprises an amine compound and water. The amine compound can be imidazole. The additive component is useful for reducing the amount of press time required during manufacture of the composite article.

摘要： An encapsulated particle comprises a core particle and a polyurethane layer disposed about the core particle. The core particle can be various particles, such as fertilizer, biocides, flame retardants, seeds, etc. The polyurethane layer comprises the reaction product of an isocyanate component and an isocyanate-reactive component. The isocyanate-reactive component comprises a graft polyol having a continuous phase and polymeric particles. A method of forming the encapsulated particle comprises the steps of providing the core particle, applying the isocyanate and isocyanate-reactive components to the core particle, and reacting the isocyanate and isocyanate-reactive components to form the polyurethane layer. The encapsulated particle has excellent physical properties, such as increased water repellency, resiliency and shelf life.
