Description

Acetic Acid Ethenyl Ester, Polymer With Sodium Ethenesulfonate is a high-performance, water-soluble copolymer designed for demanding industrial applications. This specialized polymer combines the film-forming properties of polyvinyl acetate with the superior dispersing and stabilizing characteristics of a sulfonate group, offering exceptional performance in aqueous systems. It is a critical material for manufacturers in sectors requiring robust rheology modifiers, protective colloids, or effective dispersing agents to enhance product stability and process efficiency.

Application

• Adhesives & Sealants: Acts as a key protective colloid and stabilizer in the emulsion polymerization of vinyl acetate, improving the stability, viscosity, and bonding strength of water-based adhesives.
• Paints & Coatings: Serves as an effective dispersant and rheology modifier in latex paints and architectural coatings, enhancing pigment dispersion, scrub resistance, and overall film integrity.
• Textile & Fiber Sizing: Used in warp sizing formulations to provide a strong, flexible, and water-soluble protective film on yarns, facilitating weaving and subsequent desizing.
• Paper Coating & Binding: Functions as a binder and coating agent in paper manufacturing, improving surface strength, printability, and ink holdout.
• Construction Materials: Employed as an additive in cementitious mixtures and gypsum-based products to improve workability, water retention, and adhesion.
• Personal Care & Cosmetics: Utilized as a film-forming agent, thickener, and stabilizer in hair care products, skin creams, and other cosmetic formulations.

Quality Control

Our production of Acetic Acid Ethenyl Ester, Polymer With Sodium Ethenesulfonate adheres to stringent quality management protocols. Each batch undergoes rigorous analytical testing to ensure consistent performance characteristics such as solid content, viscosity, pH, and particle size distribution. Certificates of Analysis (COA) documenting these specifications are available upon request, providing full traceability and compliance assurance for your quality systems.

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). This material is hygroscopic (moisture-sensitive). Keep away from strong oxidizing agents and extreme heat to prevent degradation of the polymer. For long-term storage, ensure containers are sealed to prevent moisture absorption and skin formation.
