Description

2-Propenoic Acid, 2-Methyl-, 2-Hydroxyethyl Ester, Polymer With Ethenylbenzene, Ethyl 2-Propenoate And 2-Propenoic Acid is a high-performance, multi-component acrylic copolymer designed for demanding industrial applications. This specialized polymer offers a unique balance of properties derived from its constituent monomers, including hardness, flexibility, and chemical resistance. It is a critical raw material for formulators in the coatings, adhesives, and advanced materials sectors seeking to enhance product durability and performance.

Application

• Industrial and Protective Coatings: Used as a key resin binder in high-performance paints, metal coatings, and corrosion-resistant finishes.
• Adhesives and Sealants: Serves as a base polymer for structural adhesives, pressure-sensitive adhesives (PSAs), and construction sealants, providing strong bonding and elasticity.
• Textile and Leather Finishes: Employed in coatings and binders to impart water resistance, durability, and improved handle to fabrics and leather goods.
• Paper and Packaging Coatings: Enhances the surface strength, printability, and moisture barrier properties of paper and cardboard.
• Plastic Modifiers and Impact Improvers: Used as an additive to modify the toughness, impact resistance, and processing characteristics of other polymer matrices.
• Specialty Inks: Acts as a vehicle resin in formulations for flexographic, gravure, and screen printing inks, contributing to adhesion and film properties.

Quality Control

Our acrylic copolymer is manufactured under a strict quality management system. Each batch undergoes rigorous testing for critical parameters including solid content, viscosity, acid value, glass transition temperature (Tg), and molecular weight distribution to ensure consistent performance and batch-to-batch uniformity. Certificates of Analysis (COA) documenting full specifications are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15-25°C (59-77°F). Keep away from heat sources and open flame. For long-term storage, consider under an inert atmosphere to prevent skin formation or polymerization.
