Description

Bis[[2-(Methacryloyloxy)Ethyl]Dimethylammonium] Sulphate is a high-purity, difunctional quaternary ammonium methacrylate salt, widely recognized for its exceptional reactivity and cationic properties. This compound is a critical building block in the synthesis of specialty polymers, where it imparts permanent positive charges and enhances adhesion to various substrates. It is essential for manufacturers in the water treatment, personal care, coatings, and advanced materials sectors seeking to develop high-performance cationic flocculants, conditioning agents, and antimicrobial surfaces.

Application

• Cationic Flocculants & Water Treatment Chemicals: A key monomer for synthesizing high molecular weight cationic polyacrylamides used in sludge dewatering, municipal wastewater treatment, and papermaking retention aids.
• Hair & Skin Care Products: Used in the production of cationic polymers that provide conditioning, detangling, and film-forming properties in shampoos, conditioners, and lotions.
• Antimicrobial & Antistatic Coatings: Enables the creation of polymers with permanent quaternary ammonium groups for durable antimicrobial surfaces on textiles, medical devices, and plastics, as well as antistatic coatings.
• Adhesion Promoters & Surface Modifiers: Improves adhesion of coatings, inks, and adhesives to challenging anionic surfaces like glass, metals, and certain plastics.
• Ion-Exchange Resins & Chromatography Media: Serves as a functional monomer for producing strong cation exchange resins and specialty separation media.
• Enhanced Oil Recovery (EOR): Used in polymer flooding formulations to modify rheology and improve oil displacement efficiency.
