Description

[(3,5,5-Trimethylhexyl)Imino]Bis(Methylene)]Bisphosphonic Acid, Potassium Salt is a high-purity, organophosphorus compound belonging to the bisphosphonate class, valued for its excellent chelating and scale inhibition properties. Its primary commercial value lies in its effectiveness as a corrosion and scale inhibitor in demanding industrial water treatment systems. This product is essential for industries requiring reliable protection for metal surfaces and heat exchange equipment, including cooling water circuits, boiler water treatment, and oilfield applications.

Application

• Industrial Water Treatment: As a key component in formulations for cooling water and boiler water systems to prevent calcium carbonate and sulfate scale formation and inhibit metal corrosion.
• Oilfield Chemicals: Used in squeeze treatments and production chemicals to control mineral scale (e.g., barium sulfate, calcium carbonate) in downhole and topside facilities.
• Detergent & Cleaning Formulations: Acts as a builder and sequestrant to inactivate water hardness ions (calcium, magnesium) in industrial and institutional cleaning products.
• Pulp & Paper Processing: Employed as a dispersant and chelant to control scale in digesters, bleach plants, and paper machines.
• Textile Processing: Used in dyeing and finishing baths to sequester metal ions that can interfere with processes and affect color quality.
• Metal Surface Treatment: Incorporated into pretreatment and plating baths for its metal-chelating and surface-modifying properties.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and 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 can lead to caking or reduced efficacy.
