Abstract
The invention comprises a composition and method for controlling the gloss of surface covering products through curing of the composition to create a wearlayer surface, and preferably on a floor covering product. The surface covering product preferably is prepared by application of an aromatic polyester acrylate composition including a flatting agent and/or hard particles, and at least one free-radical generating compound to a substrate, and then the coating is partially cured by exposure to low peak irradiance UV light in either ambient or inert air, followed by fully curing the coating with high peak irradiance UV light in preferably an inert atmosphere to form a low gloss abrasion resistant wearlayer surface. Alternatively, a high gloss wearlayer surface is obtained by solely exposing the preferred composition to high peak irradiance UV light in ambient atmosphere. Furthermore, a differential gloss flooring product is obtained by using the present inventive method described herein.
