Product Description
Product Details
Introduction
Amino Tris (methylenephosphonic acid) is referred to as ATMP.
ATMP has good chelation, low limit inhibition and lattice distortion effects. It can prevent scale-forming salts in water from forming scale, especially the formation of calcium carbonate scale. ATMP has stable chemical properties in water and is not easy to hydrolyze. When the concentration in water is high, it has a good corrosion inhibition effect.
ATMP solid is white granular, easily soluble in water, easy to absorb moisture, easy to transport and use, and is especially suitable for cold areas in winter.

Application:
ATMP is used in circulating cooling water and oil field injection water systems in thermal power plants and refineries. It can reduce corrosion and scaling of metal equipment or pipelines. ATMP is used as a metal ion chelating agent in the textile printing and dyeing industry, and can also be used as a metal surface treatment agent.
ATMP is often compounded with other organic phosphonic acids, polycarboxylic acids or salts to form organic water treatment agents, which are used in circulating cooling water systems under various water quality conditions. The dosage is preferably 1-20 mg/L; when used as a corrosion inhibitor, the dosage is 20-60 mg/L.
Electronic-grade ATMP is an acidic liquid with strong metal ion chelating ability. It can improve grinding efficiency and smoothness in the grinding, polishing, etching and other processes of semiconductor processing. It can reduce burrs and improve the surface smoothness of copper foil when used in the etching process of display panels and PCB boards.
