Description

Potassium Octyl Phosphonate CAS NO 83929-23-1 is an organophosphorus compound that serves as a highly effective corrosion inhibitor and scale control agent. Its value lies in its ability to form stable complexes with metal ions, preventing deposition and protecting industrial systems from degradation. This product is essential for water treatment specialists and formulators in the oil & gas, industrial cleaning, and cooling tower treatment industries seeking reliable performance under demanding conditions.

Application

• Industrial Water Treatment: A key component in cooling water and boiler water treatment formulations to control scale (calcium carbonate, calcium sulfate) and inhibit corrosion of ferrous and non-ferrous metals.
• Oilfield Chemistry: Used in scale inhibitor formulations for squeeze treatments and production chemicals to prevent mineral scale deposition in downhole and topside equipment.
• Metal Surface Treatment: Acts as a corrosion inhibitor in metalworking fluids, cleaning solutions, and pretreatment baths for metals.
• Detergent & Cleaning Formulations: Incorporated into industrial and institutional cleaning products for its sequestering and anti-redeposition properties.
• Pulp & Paper Processing: Functions as a dispersant and chelant to control scale in process water and improve pulp bleaching efficiency.
• Textile Processing: Used as a stabilizer and sequestrant in dyeing and finishing baths to improve process consistency and fabric quality.

Quality Control

Our Potassium Octyl Phosphonate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise chemical and physical specifications. A Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee traceability and compliance with your formulation requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which may affect product quality.
