Description

Acrylicacid,2-Sulphoethylester CAS NO 40074-09-7 is a specialized, high-purity sulfonic acid ester derivative of acrylic acid. This compound is a crucial reactive intermediate and functional monomer valued for its ability to introduce sulfonate groups, imparting enhanced water solubility, ionic character, and adhesion properties to polymer systems. It is essential for manufacturers in the coatings, adhesives, and specialty polymer industries seeking to develop advanced materials with specific performance characteristics.

Application

• Reactive Monomer for Water-Soluble Polymers: Key component in the synthesis of polyelectrolytes, dispersants, and superplasticizers for construction and industrial applications.
• UV/EB Curable Coatings and Inks: Imparts improved adhesion to difficult substrates and enhances the hydrophilicity of cured films.
• Adhesive Formulations: Used to modify acrylic pressure-sensitive adhesives (PSAs) to improve their wetting and bonding properties on polar surfaces.
• Textile and Leather Auxiliaries: Serves as a crosslinking agent or co-monomer in finishes and coatings to provide durable, hydrophilic effects.
• Personal Care and Cosmetic Polymers: Employed in the synthesis of hair fixatives, thickeners, and film-forming agents that require clarity and moisture resistance.
• Ion-Exchange Resins and Membranes: A functional monomer for creating resins with specific ion-selectivity and high capacity.

Quality Control

Every batch of Acrylicacid,2-Sulphoethylester is produced under a strict quality management system and undergoes rigorous analytical testing to ensure it meets the high standards required for industrial synthesis. Our quality control protocols include validated methods for purity, identity, and impurity profiling. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with each shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (typically 15-25°C). Keep away from heat, sparks, and open flame. Due to its reactive acrylate moiety and sulfonate group, it should be stored separately from strong oxidizing agents, bases, and amines.
