ATMP.Na4 is widely used as a scale and corrosion inhibitor in water treatment processes, particularly in cooling systems, boilers, reverse osmosis systems, and oil and gas operations. It effectively prevents the formation of calcium carbonate, calcium sulfate, and other mineral scales, ensuring efficient heat transfer and prolonging equipment life. In industrial cleaning formulations, it acts as a chelating agent to remove metal ions and prevent redeposition of soils. Additionally, it is utilized in the textile, dyeing, and paper industries to stabilize peroxide bleaching solutions, improve dye fixation, and inhibit scale formation during production. Its ability to inhibit corrosion makes it valuable in metal treatment processes, protecting surfaces from rust and degradation.
