PolyBrite® 31 CB

PolyBrite® 31 CB is a water-based styrene acrylic elastomeric coating that cures to form a seamless reflective barrier when applied over approved roofing substrates. PolyBrite® 31 CB is specifically formulated for hot dry climates and extends the life cycle of new and existing roof systems by providing protection from ultraviolet sun and other weather conditions. Its highly reflective properties keep the roof surface cool resulting in reduced building energy cost in high temperate conditions.
