Description

Tridecapotassium Hydrogen [[(Phosphonatomethyl)Imino]Bis[Ethylene[(Phosphonatomethyl)Imino]Ethylenenitrilobis(Methylene)]]Tetrakisphosphonate is a highly effective, multi-dentate chelating agent and scale inhibitor belonging to the class of phosphonate-based polymers. Its primary value lies in its exceptional ability to sequester and control problematic di- and trivalent metal ions, such as calcium, magnesium, iron, and barium, even under demanding conditions of high temperature and pH. This product is essential for industrial water treatment, detergent formulation, and oilfield applications where scale prevention and metal ion stabilization are critical for operational efficiency and equipment longevity.

Application

• Industrial Water Treatment: Primary application as a high-performance scale and corrosion inhibitor in cooling towers, boilers, reverse osmosis (RO) systems, and desalination plants.
• Detergent & Cleaning Formulations: Acts as a powerful builder and sequestrant to enhance cleaning efficacy by inactivating water hardness ions and preventing inorganic salt deposition.
• Oilfield & Mining: Used in squeeze treatments and production chemicals to prevent sulfate and carbonate scale formation in downhole and topside equipment.
• Pulp & Paper Processing: Serves as a chelant and dispersant to control metal ions that can catalyze peroxide decomposition and affect pulp brightness.
• Textile & Dyeing Auxiliary: Prevents precipitation of dyes and improves process uniformity by chelating metal ions present in process water.
• Personal Care Products: Incorporated into formulations as a stabilizing agent to improve shelf-life and product clarity.

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 may affect product quality and handling properties.
