Title: Claude L Charest: Innovator in Surface Coverings
Introduction
Claude L Charest is a notable inventor based in St-Bruno, Canada. He has made significant contributions to the field of surface coverings, holding a total of 7 patents. His innovative work focuses on the development of selectively embossed surface coverings and the processes involved in their manufacture.
Latest Patents
One of Charest's latest patents involves selectively embossed surface coverings. These coverings are created by mechanically embossing a wear layer that overlays a printing ink containing a photoinitiator, which is printed in a specific pattern or design. The embossed wear layer is then exposed to ultraviolet radiation, which cures the wear layer in the areas that are over the printing ink. The final product is fused, allowing the mechanical embossing in areas not over the printing ink to relax and become smooth. In a variant of this invention, a thermoplastic wear layer is used, which can be embossed with a different texture in the areas not covered by the printing ink. Additionally, another variant employs two different spectral regions of UV curing radiation, enabling the use of a urethane coating as a top coat on the selectively embossed surface.
