Pbtca High Efficiency Scale And Corrosion Inhibitor For Extreme Water Treatment Conditions - China

PBTCA – Low-Phosphorus High-Efficiency Scale & Corrosion Inhibitor for Extreme Water Treatment Conditions

PBTCA is a high-performance water treatment agent characterized by low phosphorus content and excellent structural properties.

It stands out for its superior scale/corrosion inhibition and compatibility, making it a top choice for global B2B partners (including water treatment operators, oilfield enterprises, and cleaning product manufacturers) in harsh operating conditions.

Basic Product Information

Performance & Applications

Core Performance

Thanks to its combined phosphonic acid and carboxylic acid structure, PBTCA delivers standout advantages:

• Low phosphorus content, with better scale & corrosion inhibition performance than conventional organophosphonic acids.

• Far superior scale inhibition under high temperatures (outperforming common organophosphonates in extreme thermal conditions).

• Enhances zinc solubility; excellent chlorine oxidation resistance; strong synergistic compounding performance.

• Acts as a high-quality stabilizer for zinc salts.

Key Application Scenarios

1 - Water Treatment Sector: ◦ Widely used as a scale & corrosion inhibitor in circulating cooling water systems and oilfield water injection systems.

◦ Ideal for scenarios requiring operation under high temperature, high hardness, high alkalinity, or high concentration multiples – especially when compounded with zinc salts or copolymers.

2 - Washing Industry: Serves as a chelating agent and metal cleaner.
