Description

Methacryloyl Oxyethyl Dimethylbenzyl Ammonium Chloride is a quaternary ammonium methacrylate monomer, a key building block for imparting permanent cationic functionality to polymers. This compound is essential for synthesizing materials with strong antimicrobial, antistatic, and adhesion-promoting properties. It is primarily sought by manufacturers in the water treatment, personal care, coatings, and specialty polymer industries for creating high-performance cationic resins and flocculants.

Application

• Water Treatment Polymers: A critical monomer for synthesizing cationic polyacrylamides and other flocculants used in sludge dewatering, municipal water purification, and industrial wastewater treatment.
• Antimicrobial Coatings & Materials: Used to create polymers with permanent, non-leaching antimicrobial surfaces for medical devices, textiles, and industrial coatings.
• Personal Care & Cosmetics: Employed in hair care products (conditioners, styling aids) and skincare formulations as a conditioning and film-forming agent in cationic polymers.
• Paper Manufacturing: Serves as a monomer for retention aids, drainage aids, and strength additives in paper and pulp processing.
• Enhanced Oil Recovery (EOR): Used in the synthesis of polymers that improve the viscosity and efficiency of flooding solutions.
• Adhesion Promoters: Incorporated into adhesive and coating formulations to improve adhesion to difficult substrates.
• Ion Exchange Resins: A functional monomer for producing strong anion exchange resins.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent absorption of atmospheric moisture. Keep away from incompatible materials such as strong oxidizing agents.
