Product Details
Polydimethyldiallylammonium chloride is offered in two physical forms: a colorless to pale-yellow viscous liquid, or a solid white-to-light-yellow powder. Both grades are completely soluble in water to form a homogeneous aqueous solution, rendering them highly suitable for water-mixing applications including a variety of water-treatment processes.

Product Application
Poly(diallyldimethylammonium chloride) finds extensive applications across multiple industries. In water treatment, it is used to purify drinking water by removing impurities, and to treat industrial wastewater from dyeing and chemical processes, as well as municipal sewage. It also aids in decolorization, filtration, and sludge dewatering. In the textile dyeing and finishing sector, it serves as a formaldehyde-free fixing agent, improving color fastness.
