Ron-Glo Fluorescent Colors are solvent-based lead free flat colors formulated for the graphics arts industry. They are designed for use on properly primed white substrates that require a high visibility paint, such as, signs, painted bulletins, exhibits, safety & aviation markings etc. Commonly used on wood, steel, canvas, vinyl, plastic and glass. Note: The lightfastness of fluorescent color is limited. Lightfastness and durability depend on 1) the thickness and uniformity of the coating and 2) the use of Ron-Glo U.V. Absorber or Vinyl Cote U.V. Absorber as a protective overcoat.
