ATMP·Na₄ is the neutral sodium salt of ATMP. It can inhibit scale formation of scaling salts in water, especially calcium carbonate scale. It is applicable for circulating cooling water in thermal power plants and refineries, oilfield water injection systems, and acts as reverse osmosis membrane scale inhibitor. ATMP·Na₄ shows good compatibility with other additives. It is especially suitable for neutral‑to‑acid formulations without ammonia odor generation.
