The product is typically an "all-organic" treatment program. Unlike traditional corrosion inhibitors that might rely on heavy metals or inorganic phosphates, all-organic programs like Nalco 2584 often utilize a blend of organic phosphonates, polymers, and copper corrosion inhibitors. Its primary function is to form a protective film on metal surfaces (such as copper, brass, and steel) to prevent the deterioration caused by water flow and oxygen.
