| Summary: | This invention is directed to a surface covering, and more particularly to a floor covering product in which a wearlayer composition, preferably an acrylated urethane composition is coated onto a polyvinyl chloride (PVC) or vinyl composition film, preferably a rigid vinyl film, and cured with low energy electron beam (EB) radiation to form a wearlayer/film composite, prior to lamination and embossing of the composite wearlayer/film to a surface covering substrate. The floor covering product may be a floor tile or a floor covering sheet.
A surface covering has a base to which is laminated a rigid vinyl film. The film is precoated with an electron beam cured wearlayer. The preferred wearlayer composition is a polymerizable organic urethane-polyester wearlayer coating. The coated printed film is prepared by application of a polyester urethane acrylate composition to a printed sheet of rigid vinyl film and the coating is exposed to a low accelerating energy Electro-curtain to form an abrasion resistant topcoat with no apparent degradation of printed rigid vinyl film. |
