APOC® 208 Silver Guard-F® Fibered Aluminum Roof Coating is a 2 pound, professional grade reflective coating formulated to provide a bright and long lasting finish. The aluminum pigment in this product enables it to form a silver shield to reflect the sun’s destructive rays. Cooling costs can be reduced while the underlying roofing materials are protected and preserved. APOC® 208 serves as a rust inhibitor and will aid in the prevention of corrosion for metal surfaces. APOC® 208 also contains interlocking fibers which increase the life and durability of the coating.
