Description

Tetrapotassium [(Isononylimino)Bis(Methylene)]Bisphosphonate is a high-performance, water-soluble organophosphonate compound. It serves as a highly effective scale and corrosion inhibitor, particularly against calcium carbonate and calcium sulfate, in demanding aqueous systems. This chemical is essential for industrial water treatment, oilfield operations, and detergent formulations where superior sequestration and threshold inhibition are required.

Application

• Industrial Water Treatment: Primary scale inhibitor in cooling towers, boilers, reverse osmosis (RO) systems, and desalination plants.
• Oilfield Chemistry: Used in squeeze treatments and as an additive in drilling and completion fluids to prevent mineral scale deposition in wells and surface equipment.
• Detergent & Cleaning Formulations: Acts as a builder and chelating agent to sequester hardness ions (Ca²⁺, Mg²⁺), enhancing cleaning efficiency in industrial and institutional cleaners.
• Pulp & Paper Processing: Prevents scale formation in digesters, bleach plants, and paper machines, improving operational efficiency and product quality.
• Textile Processing: Used in dyeing and finishing baths to control water hardness and prevent spotting or uneven dyeing.
• Metal Surface Treatment: Employed in metal cleaning and plating baths to inhibit scale and improve surface quality.

Quality Control

Our Tetrapotassium [(Isononylimino)Bis(Methylene)]Bisphosphonate is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure consistent performance and purity. A Certificate of Analysis (COA) detailing assay, active content, pH, and other critical parameters is provided with each shipment to guarantee compliance with your specifications.

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 product is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which may lead to caking or reduced efficacy.
