Description

2-Propenoic Acid, Butyl Ester, Polymer With Ethenylbenzene And Ethyl 2-Propenoate is a high-performance acrylic copolymer designed for demanding industrial applications. This versatile polymer offers a unique balance of properties, including excellent film formation, adhesion, and chemical resistance, making it a critical component in advanced coating and adhesive formulations. It is essential for manufacturers in the paints & coatings, adhesives & sealants, and specialty plastics industries seeking to enhance product durability and performance.

Application

• Industrial and Protective Coatings: A key binder in high-performance paints, varnishes, and metal coatings, providing superior weather resistance, gloss, and durability.
• Adhesives and Sealants: Used as a primary polymer in pressure-sensitive adhesives (PSAs), construction sealants, and laminating adhesives for strong, flexible bonds.
• Plastic Modifiers and Impact Improvers: Incorporated as an additive to enhance the toughness, clarity, and processing characteristics of engineering plastics and PVC blends.
• Textile and Leather Finishes: Serves as a coating resin to impart water repellency, abrasion resistance, and a soft hand feel to fabrics and synthetic leather.
• Printing Inks: Acts as a vehicle resin in flexographic and gravure inks, contributing to excellent pigment wetting, printability, and substrate adhesion.
• Paper Coatings: Used in barrier coatings and finishes to improve printability, gloss, and water resistance of paper and paperboard.

Quality Control

Our acrylic copolymer is manufactured under a stringent quality management system. Every batch is tested against rigorous in-house specifications to ensure consistent performance in viscosity, solids content, glass transition temperature (Tg), and mechanical properties. Certificates of Analysis (COA) detailing these parameters are available upon request to support your quality assurance and regulatory compliance needs.

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). Keep away from heat sources and open flame. For long-term storage, ensure containers are properly sealed to prevent skin formation or changes in viscosity.
