Description

2-Propenoic Acid, Butyl Ester, Polymer With Ethenylbenzene And 2-Hydroxyethyl 2-Propenoate is a high-performance acrylic copolymer designed to deliver exceptional durability and versatility in demanding industrial formulations. This terpolymer is engineered to provide a critical balance of adhesion, flexibility, and chemical resistance, making it a foundational component for advanced coatings and adhesives. It is essential for manufacturers in the paints & coatings, pressure-sensitive adhesives, and specialty plastics industries seeking to enhance product performance and longevity.

Application

• Industrial and Protective Coatings: Used as a key binder in solvent-based coatings for metal, plastic, and wood substrates, offering excellent weather resistance and gloss retention.
• Pressure-Sensitive Adhesives (PSAs): Serves as a primary polymer for tapes, labels, and graphic films, providing strong tack and peel adhesion.
• Automotive Refinish Paints: Imparts superior flow, leveling, and durability in automotive repair and OEM coating systems.
• Plastic Additives and Modifiers: Acts as a processing aid or impact modifier to improve the surface properties and toughness of engineering plastics.
• Printing Inks: Utilized in flexographic and gravure inks to enhance pigment binding, print clarity, and substrate adhesion.
• Textile and Leather Finishes: Applied as a finishing agent to provide water repellency, softness, and abrasion resistance to fabrics and leather goods.
