Description

2-Propenoic Acid, Butyl Ester, Polymer With Ethenyl Acetate, n-(Hydroxymethyl)-2-Propenamide And Sodium Ethenesulfonate is a specialized, multi-component polymer designed for high-performance applications. This engineered copolymer offers a unique balance of properties, including excellent adhesion, film formation, and water resistance, making it a critical raw material for demanding industrial formulations. It is primarily utilized by manufacturers in the coatings, adhesives, and textile industries seeking to enhance product durability and functionality.

Application

• Industrial Coatings Binder: Used as a key film-forming agent in water-based paints, primers, and industrial finishes, providing durability and chemical resistance.
• Adhesive Formulations: Serves as a base polymer in pressure-sensitive adhesives (PSAs) and construction adhesives, offering strong bonding and cohesion.
• Textile Finishing Agent: Applied in fabric coatings and non-woven binders to impart stiffness, water repellency, and improved handle.
• Paper Coating: Enhances the surface strength, printability, and gloss of specialty papers and paperboard.
• Leather Processing: Used in finishes and topcoats for leather goods to improve appearance, flexibility, and abrasion resistance.
• Fiberglass Sizing: Acts as a coupling agent and protective coating on glass fibers to improve compatibility with polymer matrices in composites.
