Description

n-Methacryloylethyl-N,n-Dimethylammonium-α-n-Methylcar is a specialized quaternary ammonium methacrylate monomer, a key building block in advanced polymer synthesis. Its unique cationic structure provides permanent positive charges, making it essential for creating polymers with superior adhesion, antistatic, and flocculation properties. This monomer is primarily needed by manufacturers in the water treatment, personal care, coatings, and specialty adhesives industries for developing high-performance cationic polymers.

Application

• Cationic Flocculants: A key monomer for synthesizing high-efficiency cationic polyacrylamides (CPAM) used in municipal and industrial wastewater treatment for sludge dewatering and clarification.
• Hair & Skin Care Polymers: Used in formulating cationic conditioning polymers for shampoos, conditioners, and creams, providing excellent substantivity to hair and skin.
• Antistatic Coatings: Incorporated into polymer matrices for creating durable antistatic coatings for electronics packaging, textiles, and photographic films.
• Adhesion Promoters: Enhances the adhesion of paints, inks, and adhesives to difficult-to-bond substrates like plastics and metals.
• Paper Retention Aids: Serves as a co-monomer in wet-end paper chemicals to improve fiber retention, drainage, and sheet strength.
• Oilfield Chemicals: Used in formulating drilling fluid additives and viscosity modifiers for enhanced oil recovery operations.

Quality Control

Our n-Methacryloylethyl-N,n-Dimethylammonium-α-n-Methylcar is produced under a strict quality management system. Each batch undergoes rigorous analytical testing, including assay, impurity profiling, and identity confirmation, to ensure consistency and compliance with customer specifications. Certificates of Analysis (COA) documenting purity, physical properties, and stability are available upon request.

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 / 59-77°F). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent moisture absorption and potential polymerization. Keep away from heat, sparks, and incompatible materials.
