Key Applications

DADMAC is a reactive cationic monomer that undergoes free-radical polymerization to form high-molecular-weight cationic polymers such as polyDADMAC. These polymers are valued for their charge density and flocculation performance. related Cationic Monomers

• Water treatment flocculants: Polymerized into polyDADMAC for use as primary coagulants and flocculants in municipal and industrial wastewater treatment, drinking water clarification and sludge dewatering.

• Paper and pulp chemicals: Used to produce cationic polymers that improve retention, drainage, dry strength and sizing in papermaking processes.

• Textile and dyeing auxiliaries: Applied in the synthesis of cationic polymers for dye fixation, antistatic finishing and improved color fastness on fabrics.

• Oilfield and mining chemicals: Incorporated into formulations for drilling fluids, fracturing fluids and mineral processing where cationic charge is required.

• Specialty polymer synthesis: Serves as a key building block for copolymers with acrylamide, acrylic acid and other monomers in functional polymer production.
