Abstract
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.
