Description

Dimethylamine-Epichlorohydrin Copolymer is a synthetic cationic polyamine polymer formed from the reaction of dimethylamine and epichlorohydrin. This compound is valued for its strong cationic charge and flocculating properties, making it an effective agent for clarifying and separating suspended solids. It is primarily used by industries requiring efficient water treatment, paper manufacturing, and mineral processing solutions.

Application

• Water & Wastewater Treatment: Acts as a primary coagulant and flocculant for the removal of suspended solids, organic matter, and color in industrial and municipal water systems.
• Paper & Pulp Industry: Used as a retention and drainage aid to improve fiber retention, sheet formation, and water removal on the paper machine wire.
• Mineral Processing: Employed as a selective flocculant and settling aid in the beneficiation of ores such as iron ore, potash, and coal.
• Sugar Refining: Facilitates the clarification process by removing impurities and non-sugars from cane or beet juice.
• Textile Industry: Serves as a dye-fixing agent and coagulant in textile effluent treatment.
• Oilfield Applications: Used in drilling muds and as a water clarifier for produced water.
