As a topcoat, it is suitable in heavy-duty applications such as restrooms/lockers, kitchens, cafeterias, equipment maintenance areas, laboratories, manufacturing facilities, processing areas, bottling/packaging areas, and other areas requiring a chemical resistant, sanitary, high impact, solid color finish.
