Henry 887 Tropi-Cool 100% Silicone Roof Coating is a premium, 100% silicone, moisture-cure coating designed to reflect the sun's heat and UV 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 ponding water resistance, extreme durability, and superior capabilities of sealing and protection.
