Description

2-Propenoic Acid, Butyl Ester, Polymer With Ethenyl Acetate And Sodium Ethenesulfonate is a specialized terpolymer designed to deliver a unique balance of properties from its constituent monomers. This product, identified by CAS NO 66573-43-1, is engineered to provide excellent film-forming characteristics, adhesion, and water solubility or dispersibility. It is a critical raw material for formulators seeking to enhance the performance and stability of aqueous-based systems. Key industries that utilize this advanced polymer include coatings, adhesives, textiles, and personal care.

Application

• Water-Based Coatings & Inks: Acts as a film-forming agent and binder, providing good gloss, adhesion to various substrates, and scrub resistance.
• Adhesives & Sealants: Used as a base polymer in pressure-sensitive adhesives (PSAs) and construction adhesives, offering tack and cohesion.
• Textile Finishing & Sizing: Imparts stiffness, hand feel, and durability to fabrics, and serves as a protective coating for yarns.
• Personal Care & Cosmetics: Functions as a film former and fixative in hair styling products, mascara, and nail polish.
• Paper Coatings: Enhances surface strength, printability, and gloss of paper and paperboard.
• Leather Finishing: Used in topcoat formulations to provide a flexible, durable, and water-resistant finish.
• Construction Additives: Incorporated into cementitious mixtures and mortars to improve workability, adhesion, and reduce water absorption.

Quality Control

Our 2-Propenoic Acid, Butyl Ester, Polymer With Ethenyl Acetate And Sodium Ethenesulfonate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistency in critical parameters such as solid content, viscosity, pH, and particle size. Certificates of Analysis (COA) documenting these specifications are available upon request. Our production adheres to ISO 9001 standards, and the product complies with relevant global regulatory frameworks including REACH.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C/59-77°F). This product is hygroscopic (moisture-sensitive); ensure containers are sealed immediately after use to prevent absorption of atmospheric moisture which may affect product performance. Keep away from heat sources and open flames. For optimal shelf life, avoid freezing.
