Abstract: A decorative panel is provided including a center ply formed from a wood veneer, a back ply formed from a kraft liner board or paperboard, and a free ply. The face ply includes a kraft linear backing sheet to which a topcoated thin decorative paper is laminated. The face ply is secured to the center ply by appropriate application of adhesive, heat and pressure.

Abstract: A method of manufacturing paneling and the like in which the thickness or weight of coatings applied to substrate materials is measured by infrared absorption providing a digital representation, accurate to 0.01 mil, of the coating's thickness or weight to 0.01 gram/sq. ft. The rate of application of the coating is adjusted in accordance with the measurement to maintain the coating weight or thickness within optimum limits.

Abstract: A paint applicator for direct roll coating of textured panels or sheet-like members comprises a core, a layer of fibrous web material disposed over the core, a protective plastic tube member disposed around the layer of fibrous web material, and a layer of woven material disposed over the protective tube member. The fibrous web allows for uniform application of the paint film due to its softness and ability to follow contoured surfaces. The protective tube member prevents paint from penetrating the fiber web. The woven material carries the paint on the roll applicator.

Abstract: A lamination process is provided for the lamination of a vinyl film to a cellulosic substrate, such as a wood product, e.g., particleboard, wherein grain swelling of the substrate is avoided. The process involves coating the wood product substrate with an organic polyisocyanate having at least two active isocyanate groups per molecule as a primer coat, and thereafter applying a vinyl acetate-ethylene copolymer emulsion adhesive to the primed substrate to form an interlaminate adhesive layer. A vinyl polymeric film is then applied to the adhesive-coated substrate to form a permanently bonded laminate of the substrate and the film. The lamination process of the present invention is particularly suitable for use in a continuous hot-line heat reactivated laminating procedure.

Abstract: A low pressure heat resistant decorative laminate material comprises a wood base member directly secured to a decorative plastic film by an adhesive having aluminum powder dispersed therein.

Abstract: The adhesion of a heat activatable polyurethane adhesive to a vinyl substrate is improved by admixing the adhesive with an N-substituted-2-pyrrolidone and/or an ethoxylated alkyl phenol.

Abstract: A cellulosic substrate is coated by applying a polyurethane adhesive thereto, drying the adhesive, coating the adhesive with an ultraviolet curable solid polyacrylate resin and then curing the composite structure with ultraviolet rays.

Abstract: In a process for surfacing a hardwood veneer with a plastic film, one surface of the hardwood veneer is first sanded to provide a smooth surface for prefinishing, followed by the application of a stain or toner to achieve the desired color and appearance of the panel. A first coat of adhesive is applied to the smooth surface of the panel and allowed to dry, followed by the application of a second coat of adhesive which is also subsequently dry. Next, the panel is heated to reactivate both coats of adhesive, and a clear plastic film is applied to the smooth surface of the hardwood veneer and laminated thereto. Next, an ultra-violet curable topcoat is applied to the plastic sheet and allowed to cure, thereby resulting in a surface that has excellent scratch, mar and burnish resistance.

Abstract: A vinyl film-wood product substrate laminate is formed using as an adhesive a mixture of a vinyl acetate-ethylene emulsion and an admixture of toluene and N-lower alkyl substituted pyrrolidone.

Abstract: The flame spread rating of Lauan plywood panels is reduced significantly by incorporating, just prior to application, a quantity of sodium bicarbonate in dry powder form or slurry and a quantity of a saturated aqueous solution of sodium tetraborate, respectively, in the water base filler and the water base basecoat used to finish the surface thereof.
