Abstract
Abstract A coating composition for forming abrasion-resistant, high clarity coatings is described. It has been found that a macrocrystalline or single crystal mineral abrasive can be added at high levels, about 5 to about 80 percent by weight, to art-recognized film-forming resin compositions for producing coatings exhibiting exceptional abrasion resistance and clarity. Such a coating composition is useful for application to surfaces including wood, vinyl, tile, rubber modified cement, marble, metal, plastic, and laminated surfaces.
