Description

Poly(Dimethylamine-Co-Epichlorohydrin) is a cationic, water-soluble polymer synthesized from dimethylamine and epichlorohydrin. This versatile polyamine-epichlorohydrin resin is valued for its strong cationic charge and ability to function as a highly effective flocculant, retention aid, and charge neutralizer in aqueous systems. It is a critical specialty chemical for industries requiring efficient solid-liquid separation, process water clarification, and surface modification. Key industrial users include paper manufacturers, water treatment facilities, and producers of personal care products.

Application

• Paper and Pulp Industry: Primary use as a wet-strength resin and retention/drainage aid to improve paper quality and production efficiency.
• Water and Wastewater Treatment: Acts as a highly effective cationic flocculant for clarifying process water, treating municipal/industrial wastewater, and sludge dewatering.
• Personal Care and Cosmetics: Utilized as a conditioning agent and viscosity modifier in hair care and skincare formulations.
• Textile Industry: Serves as a dye-fixing agent and finishing chemical to improve color fastness and fabric properties.
• Oilfield and Mining: Applied in drilling muds and as a process aid for solid separation and water clarification.
• Sugar Refining: Used as a clarificant to remove impurities during the sugar production process.
