Hpaa High Efficiency Corrosion Inhibitor For Low Hardness Water Systems - China

HPAA – High-Efficiency Corrosion Inhibitor for Low-Hardness Water Systems

HPAA is a high-performance, eco-friendly corrosion inhibitor with exceptional stability and superior protective effects.

Basic Product Information

• Chemical Name: 2-Hydroxyphosphonocarboxy lic Acid (HPAA)

• Aliases: Phosphonylhydroxyacetic Acid; Hydroxyphosphonoacetic Acid; HPA

• CAS No: 23783-26-8

• Molecular Formula: C₂H₅O₆P

• Relative Molecular Mass: 156

Performance & Applications

Core Performance

HPAA delivers standout advantages for industrial water treatment:

• Excellent Chemical Stability: Resistant to hydrolysis and degradation by acids/alkalis; safe, non-toxic, and pollution-free.

• Superior Corrosion Inhibition: Acts as a highly effective cathodic corrosion inhibitor – its corrosion control performance is 5–8 times better than HEDP and EDTMP.

• Enhanced Zinc Solubility: Boosts the solubility of zinc (a key synergistic corrosion inhibitor), further improving protective effects.

Target Application Scenarios

Widely used in circulating cooling water systems across:

• Steel, petrochemical, power, and pharmaceutical industries.

• Ideal for low-hardness, easily corrosive water conditions (common in southern regions), effectively mitigating metal equipment/pipeline corrosion.

3.0 Usage Guidelines

• HPAA forms high-performance organic corrosion and scale inhibitors when combined with low-molecular-weight polymers.

• Its effect is further enhanced when compounded with zinc salts (recommended for optimal corrosion protection).

Packaging & Storage

• Packed in 30kg plastic drums (customizable per user needs).

• Store in a cool indoor area.

Shelf life: 12 months.

Safety Precautions

HPAA is an acidic liquid.

Use labor protection measures during operation: Avoid contact with skin or eyes.

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