Applications

1. Wastewater Treatment & Sludge Dewatering A high-charge cationic flocculant for municipal and industrial wastewater treatment. Neutralizes anionic pollutants and bridges suspended solids for rapid flocculation, delivering clear effluent and efficient sludge dewatering across treatment plants.

2. Papermaking Wet-End Additives An effective retention, drainage and charge-control agent in papermaking. Improves fines retention, drainage speed and paper strength while capturing anionic trash, enhancing machine efficiency and sheet quality.

3. Drinking & Industrial Water Treatment A reliable coagulant aid for potable and process water clarification. Consistent quality and low residual monomer content support safe, compliant water treatment operations.

4. Oilfield & Produced Water Treatment Removes oil, solids and hardness from produced water and drilling fluids. High charge density and thermal stability deliver effective separation in demanding oilfield environments.

5. Textile & Dye Fixation A cationic dye-fixing agent for direct and reactive dyes, improving color fastness and reducing dye bleeding. Enhances fabric quality while minimizing dye loss in effluent.

6. Personal Care & Specialty Applications A conditioning cationic polymer for hair care products and specialty formulations. Provides softness, manageability and anti-static benefits with mild, stable performance.
