Description

Aminotrimethylenephosphonic Acid Potassium Salt is a highly effective phosphonate-based scale and corrosion inhibitor. This compound is valued for its superior chelating power and stability across a wide pH range, making it a critical component in water treatment formulations. It is primarily utilized by industrial facilities, chemical manufacturers, and water treatment specialists to protect equipment and improve process efficiency.

Application

• Industrial Water Treatment: Key ingredient in formulations for scale and corrosion inhibition in cooling towers, boilers, and reverse osmosis systems.
• Detergent & Cleaning Agents: Acts as a builder and chelating agent to enhance cleaning power by sequestering metal ions in hard water.
• Oilfield Chemicals: Used in scale squeeze treatments and as a component in drilling fluids to prevent mineral scale deposition.
• Pulp & Paper Industry: Employed as a chelant in bleaching processes and to control metal ion catalysed decomposition of hydrogen peroxide.
• Textile Processing: Serves as a stabilizer and sequestrant in bleaching, dyeing, and finishing baths to improve quality and consistency.
• Personal Care Products: Functions as a chelating agent in formulations such as shampoos and liquid soaps to improve stability and shelf life.

Quality Control

Our Aminotrimethylenephosphonic Acid Potassium Salt is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for active content, pH, and impurity levels. Certificates of Analysis (COA) are provided and the product can be supplied to meet relevant industry standards upon request.

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 product is hygroscopic (moisture-sensitive); ensure containers are kept tightly sealed to prevent absorption of atmospheric moisture, which can lead to caking or reduced efficacy.
