Abstract
A method for coating laminate and composite wood products with a polymer coating. The method includes providing a wood substrate consisting of an engineered or composite wood product, applying a flowable but thixotropic polymer coating material to the surface of the substrate, distributing the polymer coating material evenly across the surface of the wood substrate to create a continuous smooth surface, and allowing the polymer coating material to bond to the surface of the wood substrate to form a hard smooth surface over the wood substrate surface.
Claims25
A method for the production of laminated wood products comprising:
- (a) applying a thermal setting adhesive to a plurality of sheets of wood veneer;
- (b) heating the plurality of sheets of wood veneer to a temperature above ambient temperature and applying pressure to the plurality of sheets of wood veneer, thereby causing the plurality of sheets of wood veneer to be bonded to one another by the thermal setting adhesive, and creating a layered wood substrate;
- (c) before the layered wood substrate cools to ambient temperature, applying a solvent-free flowable but thixotropic polymer coating material to one or more surfaces of the layered wood substrate;
- (d) distributing the polymer coating material evenly across one or more surfaces of the layered wood substrate such that any holes and imperfections in said surface are filled and a smooth continuous surface is created;
- and
- (e) allowing the polymer coating material to bond to one or more surfaces of the layered wood substrate and cure to form one or more hard, smooth surfaces over the layered wood substrate surface.
