PG 600 non-fibered aluminum roof coating is a reflective coating designed to protect a variety of asphalt-based roofs and most metal roof substrates. When applied to the roof, the aluminum flakes leaf to the surface, forming a reflective, metallic shield over the base material. PG 600 contains a soft-settle formulation for easier mixing and is specifically formulated to be compatible with Polyglass roofing membranes.
