Description

2-Propenoic Acid, 2-Methyl-, 1,2-Ethanediyl Ester, Polymer With Ethenylbenzene, Chloromethylated, 2-(Dimethylamino)Ethanol-Quaternized is a specialized cationic polymer with a complex quaternary ammonium structure, offering unique surface-active and charge-modifying properties. This compound is engineered to provide exceptional performance as a flocculant, retention aid, and charge neutralizer in demanding aqueous systems. It is a critical material for industries requiring advanced water treatment, paper manufacturing, and mineral processing solutions where controlling colloidal stability and enhancing solid-liquid separation are paramount.

Application

• Water & Wastewater Treatment: Acts as a highly effective cationic flocculant for the clarification of industrial process water, municipal wastewater, and sludge dewatering.
• Paper & Pulp Manufacturing: Serves as a powerful retention and drainage aid, improving fiber and filler retention on the paper machine wire and enhancing water removal.
• Mineral Processing: Used as a selective flocculant and dewatering agent in the beneficiation of ores such as iron ore, potash, and coal.
• Oilfield & Drilling Fluids: Functions as a shale inhibitor and fluid loss control additive in water-based drilling muds.
• Textile Processing: Employed as a dye-fixing agent and for the treatment of dyehouse effluents to remove color and suspended solids.
• Personal Care & Cosmetics: Utilized as a conditioning agent and viscosity modifier in hair care and skincare formulations.
