Widely used in water treatment processes, this chemical acts as a cationic flocculant to remove suspended solids, organic matter, and negatively charged particles from wastewater. It is effective in clarifying water in municipal and industrial treatment plants, especially in sewage and sludge dewatering applications.

Commonly employed in the paper industry to improve dry strength and retention during papermaking. It enhances fiber bonding and helps in the efficient retention of fillers and additives, leading to stronger paper and reduced raw material loss.

In the textile industry, it serves as a dye-fixing agent and improves the wash-fastness of fabrics. It also functions as a surface modifier for fibers, increasing their affinity for dyes and finishes.

Used in the production of specialty polymers and coatings where cationic functionality is required. Its reactivity allows for copolymerization with other monomers to create tailored polymers for adhesives, coatings, and personal care products.

Also found in some cosmetic and personal care formulations, such as hair conditioners and skin care products, where it provides antistatic properties and improves the deposition of active ingredients on hair or skin surfaces.
