Description

Methacryloyl Oxyethyl Dimethylethyl Ammonium Ethylsulfate is a specialized quaternary ammonium methacrylate monomer, a key building block for imparting permanent cationic functionality to polymers. This compound matters for its ability to introduce positive charges into polymer chains, which is essential for applications requiring strong adhesion, antistatic properties, or interaction with negatively charged surfaces. Industries such as water treatment, personal care, textiles, and coatings rely on this monomer to develop high-performance, functional materials with enhanced properties.

Application

• Flocculants and Coagulants: A primary monomer for synthesizing cationic polyacrylamides (CPAM) used in municipal and industrial wastewater treatment to clarify water and sludge dewatering.
• Hair and Skin Care Products: Used in the production of cationic conditioning polymers for shampoos, conditioners, and creams, providing excellent moisturization, detangling, and softness.
• Textile and Paper Chemicals: Serves as a key component in fabric softeners, dye fixatives, paper retention aids, and drainage aids, improving process efficiency and product quality.
• Adhesives and Sealants: Enhances adhesion to challenging substrates (e.g., glass, metals, plastics) by incorporating cationic sites into acrylic and pressure-sensitive adhesive (PSA) formulations.
• Coatings and Inks: Imparts antistatic properties, improves pigment dispersion, and enhances substrate wetting and adhesion in various coating systems.
• Oilfield Chemicals: Used in drilling muds and completion fluids as a shale inhibitor and viscosity modifier.
• Ion Exchange Resins: A functional monomer for creating strong acid cation exchange resins or specialty resins with tailored selectivity.

Quality Control

Our Methacryloyl Oxyethyl Dimethylethyl Ammonium Ethylsulfate is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including assay, identity confirmation, and impurity profiling, to ensure it meets precise specifications for polymerization-grade monomers. A comprehensive Certificate of Analysis (COA) detailing purity, inhibitor content, and physical properties is provided with each shipment to guarantee consistency and performance in your formulations.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). This product is hygroscopic (moisture-sensitive) and must be kept under an inert atmosphere (e.g., nitrogen) after opening to prevent moisture absorption and premature polymerization. Keep away from heat, sparks, and incompatible materials such as strong oxidizing agents.
