PC-825PA is a high solids, color stable aliphatic polyurea coating. PC-825PA may be applied directly to most substrates and may be used as a topcoat for existing epoxy, polyurethane, or polyurea. This coating is extremely color stable and displays excellent UV weathering characteristics. PC-825PA may be applied in temperatures as low as 20°F. When fully cured, PC- 825PA will produce a highly abrasion resistant, high- gloss, smooth finish.
PC-825PA adheres well to most substrates including concrete, steel, wood and plastic. The high tensile strength of the coating is able to withstand the abuse of industrial equipment, steel-wheeled carts and forklifts. The excellent chemical resistance is well suited for many harsh applications.
