Chemical Structure

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.

• Product Quality & Consistency: Product specifications can be confirmed by COA before shipment. Batch quality and key parameters are reviewed according to customer requirements.

• International Logistics & Supply Stability: Export supply can be arranged through suitable logistics channels. Shipment planning can be discussed according to product properties and destination requirements.

• Safety Documentation & Regulatory Compliance: SDS, COA and shipping documents can be prepared for customer review. Documentation support is available for B2B chemical procurement.

Safety, Handling & Documentation

Standard industrial hygiene practices should be followed when handling this product. Avoid direct contact with skin and eyes. Use appropriate personal protective equipment such as gloves, safety goggles and protective clothing. Ensure adequate ventilation in the working area.

• Handling: Avoid inhalation of vapors or mists. Wash hands and exposed skin thoroughly after handling. Do not eat, drink or smoke in the handling area.

• Storage: Store in a cool, dry, well-ventilated area away from incompatible materials such as strong oxidizers and reducing agents. Keep containers tightly closed when not in use. Protect from freezing where applicable.

• Documentation: Refer to the final SDS before handling, storage and transportation. SDS and COA are available for customer evaluation. Final handling, storage and transportation requirements should follow the supplier SDS and carrier review.
