Abstract: The invention relates to a process for coating powders on wood substrate comprising pre-treating at least one surface of the substrate with a substantially solvent free treating composition, applying a powder coating composition on the pre-treated surface of the substrate; and curing the powder coating composition. The treating composition includes at least one thermoset material and has a viscosity that is sufficiently low to allow the treating composition to wet out the surface(s) of the substrate and to penetrate into the surface fiber structure of the substrate.

Abstract: A one-package heat curable polyurethane composition, comprising an isocyanate terminated prepolymer liquid phase and a separate solid polyhydroxy compound phase insoluble in the prepolymer phase, and suitable for use as an adhesive. The liquid prepolymer phase comprises the reaction product of an aromatic polyisocyanate and a polyhydroxy compound. The separate insoluble solid polyhydroxy compound phase is dispersed or suspended throughout the liquid prepolymer phase and remains separate until heat cured. The ratio of OH groups in the solid polyhydroxy compound phase to NCO groups in the isocyanate terminated prepolymer liquid phase is less than 2:1. The one-package polyurethane adhesive composition can also be useful as an in-mold coating and an injection molding compound.

Abstract: A mechanically peelable masking coating composition particularly useful for metals, and the method of preparing same for use is provided. The composition is heat curable in one or two heatings to produce a firmly adhering yet peelable coating. In its preferred form the composition comprises a mixture of a dispersion grade vinyl, a plasticizer, an adhesion promoter such as an epoxy, and optionally a thixotrope where greater resistance to sag and flow are desired. No fugitive solvents are required.

Abstract: The disclosed one-part curable polyurethane prepolymer compositions comprise a continuous phase and, distributed uniformly through this phase, a discontinuous phase containing a polyol curing agent of the pentaerythritol type. At moderately elevated temperatures, the polyol phase begins to enter into a curing reaction which has a single exotherm peak. The prepolymers are made from aliphatic or cycloaliphatic polyisocyanates and polymeric polyols. The one-part curable system is stable for long periods at room temperature. The curable polyurethane systems can be used in adhesives, coatings, sealants, and similar applications.
