CAS No.:: 6419-19-8
Another name: Dequest 2000
Molecular Formula: N(CH2PO3H2)3 Molecular weight: 299.05
Structural Formula:
Product performance:
ATMP has excellent chelation, low threshold inhibition and lattice distortion ability. It can prevent scale formation, especially for the formation of calcium carbonate. ATMP has good chemical stability and is hard to be hydrolyzed in water system. It will have good corrosion inhibition when the concentration is high in the water.

Range of application:
ATMP is used in the circulating cooling water systems and oilfield water injection system at thermal power plant and refinery plant. It can reduce the corrosion and scale of metal equipment and pipeline. ATMP can be used as chelating agent in textile dyeing industries and as metal surface treatment agent.
Usage:
ATMP is usually used together with organic phosphonic acid、polycarboxylic acid and salt to form into organic alkaline water treatment agent, thus can be used in different circulating cooling water systems under different water quality conditions. The dosage of 1-20mg/L is recommended. As corrosion inhibitor, the dosage of 20-60mg/L is preferred.
Package and Storage:
Normally In 30kg or 250kg net Plastic Drum, IBC drum can also be used as required.
Storage for ten months in room shady and dry place.
