Atmp High Efficiency Chelating Scale Inhibitor For Industrial Water Treatment And Beyond - China

ATMP (Amino Trimethylene Phosphonic Acid) – High-Efficiency Chelating Scale Inhibitor for Industrial Water Treatment & Beyond

ATMP is a high-performance chelating agent and scale inhibitor with excellent stability and multi-scenario adaptability.

It is widely recognized by global B2B partners (including water treatment operators, power plant managers, and industrial manufacturing enterprises) for its reliable anti-scaling, corrosion-inhibiting, and metal ion control capabilities.

Basic Product Information

• Chemical Name: Amino Trimethylene Phosphonic Acid (ATMP)

• Aliases: Aminotris(methylenephosph onic acid), ATMPA, Nitrilotrimethylene Triphosphonic Acid

• CAS No: 6419-19-8

• Molecular Formula: N(CH₂PO₃H₂)₃

• Relative Molecular Mass: 299.05

Performance & Applications

Core Performance

ATMP exhibits excellent chelating, threshold inhibition, and lattice distortion effects:

• Effectively prevents scaling (especially calcium carbonate scaling) from scale-forming salts in water.

• Chemically stable in water, not prone to hydrolysis.

• Delivers good corrosion inhibition when used at higher concentrations in water.

Key Applications

It is widely used in industrial scenarios:

1 - Water Treatment Systems: Applied in circulating cooling water systems (thermal power plants, refineries) and oilfield reinjection water systems, reducing corrosion and scaling of metal equipment/pipelines.

2 - Textile & Metal Processing: Used as a metal ion chelating agent in textile printing and dyeing, and as a metal surface treatment agent.

3 - Solid Form Advantage: ATMP solid (crystalline powder) is soluble in water, hygroscopic, easy to transport and use – especially suitable for cold regions in winter.

ATMP is often compounded with other organic phosphonic acids, polycarboxylic acids or their salts to form organic water treatment agents, suitable for circulating cooling water systems under various water quality conditions:

• As scale inhibitor: Recommended dosage: 1–20 mg/L

• As corrosion inhibitor: Recommended dosage: 20–60 mg/L

Packaging & Storage

• Liquid ATMP: Packed in plastic drums, 30kg/drum or 250kg/drum.

• Solid ATMP: Packed in plastic woven bags lined with polyethylene bags, 25kg/net bag (customizable per user needs).

• Storage: Keep in a cool, ventilated indoor area; protect from moisture and direct sunlight.

Shelf life: 10 months.

Safety Precautions

ATMP is acidic.

Take labor protection measures during operation: Avoid contact with skin and eyes.

If contact occurs, rinse immediately with plenty of clean water.
