COMPOSITIONS AND METHODS FOR SEALING NATURAL STONE TILES AND NATURAL STONE ARTICLES

摘要

The present invention relates to a method of sealing natural stone tiles and stone articles by applying and curing by UV radiation a liquid, solventless sealant onto natural stone tiles and articles to provide permanent protection, abrasion resistance, chemical and stain resistance and resistance to mold and other biological growth stains. The UV-curable solventless sealing composition comprises an effective amount of carboxyl functional, UV- curable reagent to provide for adhesion of the cured coating to the stone article. Additionally, the method describes the application of an optional liquid primer sealant comprising a UV- curable aqueous dispersion of an acrylate-functional resin.
