Dimethylamine-epichlorohydrin copolymer

Dimethylamine-epichlorohydrin copolymer (CAS 25988-97-0), approved as E1063, is a cationic polyelectrolyte used across water treatment and process industries to destabilize suspended particles and facilitate their removal.

Its positive charge density makes it effective as a primary coagulant or coagulant aid in clarification processes. In municipal and industrial water treatment, it coagulates colloidal solids, turbidity, and negatively charged contaminants.

This process significantly reduces downstream filtration load. Pulp and paper producers apply it for retention aid and drainage improvement during sheet formation, directly impacting production efficiency and fiber recovery.

Textile and dyehouse effluent treatment relies on it to precipitate reactive and disperse dyes from wastewater before discharge. In leather processing, it supports chrome and tannin removal from tannery effluents.

These applications help operations meet discharge compliance targets. The product is supplied as an aqueous solution, typically at concentrations ranging from 40% to 65% active content for industrial use.

Technical grade is the standard commercial form for industrial water treatment and process applications. Food-contact and potable water approvals vary by market and specific regional regulations.

Buyers should confirm compliance documentation against regional regulatory requirements before sourcing. This ensures the material meets all necessary safety and performance criteria for the intended application.
