Description

2-(Dimethylamino)Ethyl Methacrylate, Sulphate is a specialized quaternary ammonium salt monomer, a key building block for imparting cationic functionality to polymers. This compound is essential for creating materials with permanent positive charges, which are critical for applications requiring adhesion, flocculation, or antimicrobial properties. It is primarily sought by formulators and manufacturers in the water treatment, personal care, coatings, and specialty polymer industries.

Application

• Cationic Flocculants: A key monomer for synthesizing high-performance cationic polyacrylamides used in municipal and industrial wastewater treatment for sludge dewatering and clarification.
• Antimicrobial & Biocidal Polymers: Used to create polymers with inherent, non-leaching antimicrobial properties for coatings, textiles, and medical devices.
• Paper Retention Aids & Dry Strength Agents: Essential in paper manufacturing to improve retention of fines and fillers, and to enhance paper strength.
• Hair & Skin Care Products: Employed in cationic conditioning polymers for shampoos, conditioners, and lotions to provide superior substantivity and feel.
• Adhesion Promoters: Used in coatings, inks, and adhesives to improve adhesion to difficult substrates like metals and plastics.
• Oilfield Chemicals: A component in drilling fluid additives and enhanced oil recovery (EOR) polymers for viscosity control and clay stabilization.
• Dye Fixatives & Textile Auxiliaries: Improves dye fastness and acts as a softening agent in textile processing.
