Pro-Grade^® 988 Silicone White Roof Coating is a solvent-free, one-component, moisture-curing silicone rubber roof coating system for use on existing smooth asphaltic BUR, smooth or granulated cap sheet, single ply roof membrane, well-adhered acrylic coating, metal, sprayed-in-place polyurethane foam and various aged membrane roofing. The system provides long-term weathering protection and resists the effects of ozone, ultraviolet radiation and temperature extremes. With its high solids content and absence of hydrocarbon solvents, Pro-Grade^® 988 Silicone White Roof Coating can be applied in excess of 50 mils in a single coat without blistering, while maintaining maximum adhesion.
