Property and Uses
ATMP has good chelating, low limiting lattice effects. It can prevent the formation of water scale, especially the formation of calcium carbonate. This product is chemically stable in water and is not easily hydrolyzed. At a higher concentration in water, it has a good corrosion inhibition effect.
ATMP is used in thermal power plants, oil refineries' circulating cooling water, oilfield return water systems. It can play a role in reducing the corrosion and scaling of metal equipment or pipelines. It is also 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, etc.
ATMP is a crystalline powder solid, soluble in water, prone to moisture absorption, easy to transport and use, especially suitable for cold regions in winter.

How to use
ATMP is often formulated with other organic acids, polycarboxylic acids, or salts to form organic water treatment agents, which are used in various circulating cooling water systems under different water conditions. The dosage is optimal at 1-20mg/L; when used as a corrosion inhibitor, the dosage is 20-60mg/L.
Packaging and storage
Amino Trimethylene Phosphonic Acid Liquid, often packed in plastic drums, each drum weighs 30KG, 25KG; solid is packed in plastic woven bags with lining, each bag weighs 25KG, which can be determined according to the user's needs. Store in a cool and ventilated place indoors, keep dry, strictly prohibit exposure to the sun, and the storage period is ten months.
Safety protection
Amino Trimethylene Phosphonic Acid ATMP is acidic, operation precautions labor protection, should avoid contact with skin, eyes, contact should be immediately washed with plenty of water.
