Description

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

Application

• Industrial and Protective Coatings: Used as a key binder in solvent-based or high-solid coatings for metal, wood, and plastic substrates, providing excellent weather resistance and adhesion.
• Adhesives and Sealants: Serves as a primary polymer in the formulation of pressure-sensitive adhesives (PSAs), construction sealants, and assembly adhesives, offering tack and cohesive strength.
• Printing Inks: Employed in the manufacture of specialty printing inks, contributing to film formation, gloss, and substrate anchorage.
• Textile and Leather Finishes: Acts as a coating or finishing agent to impart water repellency, softness, and abrasion resistance to fabrics and leather goods.
• Plastic Modifiers: Utilized as an impact modifier or processing aid to enhance the toughness and flexibility of rigid plastic compounds.

Quality Control

Our production of 2-Propenoic Acid, Polymer With Ethenylbenzene And 2-Ethylhexyl 2-Propenoate adheres to stringent quality management protocols. Each batch is characterized for critical parameters including solid content, viscosity, acid value, and glass transition temperature (Tg) to ensure batch-to-batch consistency and performance reliability. Certificates of Analysis (COA) documenting these 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 room temperature (typically 15-25°C). Keep away from heat sources and open flame. For long-term storage, ensure containers are sealed to prevent moisture absorption or solvent evaporation, which may alter product properties.
