Henry 887HS Tropi-Cool 100% silicone white roof coating is a moisture cure coating designed to reflect the sun's heat and UV (ultraviolet) rays as well as protect many types of roofs. While suitable for use in all climates, the 100% silicone chemistry is especially suited for extreme tropical environments, which are exposed to some of the hottest and wettest weather with intense UV exposure. It is specially designed to maintain maximum reflectivity of heat and UV rays as it ages. Its moisture cure chemistry creates a very aggressive chemical bond with the roof, which provides permanent resistance to ponding water, extreme durability, and superior capabilities of sealing and protection. Features: Lifetime warranty, saves energy by reflecting heat, excellent adhesion and flexibility, long-lasting waterproof seal, 1 coat application, and rain-safe in 1 hour. VOC compliant, solvent-free. Wide application temperature range from 35 F (degrees Fahrenheit) to 120 F. Mold and mildew resistant. Easy to apply by spray, roller, or brush.
