Description

2-Propenoic Acid, Polymer With 2-Ethylhexyl 2-Propenoate is a high-performance acrylic copolymer, also known by its CAS number 25134-51-4. This versatile polymer is engineered to deliver excellent film-forming properties, durability, and chemical resistance, making it a critical raw material for advanced coatings and adhesives. It is essential for manufacturers in the paints & coatings, pressure-sensitive adhesives, textiles, and construction materials industries seeking to enhance product performance and longevity.

Application

• Architectural and Industrial Coatings: Used as a primary binder in water-based paints and varnishes, providing excellent gloss, weatherability, and adhesion to various substrates.
• Pressure-Sensitive Adhesives (PSAs): Serves as a key component in adhesive formulations for tapes, labels, and graphic films, offering a balance of tack, peel strength, and cohesion.
• Textile Finishing and Non-Woven Binders: Imparts durability, water resistance, and soft hand feel to fabrics and non-woven materials.
• Construction Chemicals: Incorporated into cement modifiers, sealants, and caulks to improve flexibility, water resistance, and bond strength.
• Printing Inks: Used in flexographic and gravure ink formulations to enhance pigment binding, gloss, and rub resistance.
• Leather Finishing: Applied as a topcoat to provide a protective, flexible, and glossy finish on leather goods.

Quality Control

Our 2-Propenoic Acid, Polymer With 2-Ethylhexyl 2-Propenoate is manufactured under a stringent quality management system. Each batch undergoes rigorous testing for critical parameters including solids content, viscosity, pH, glass transition temperature (Tg), and mechanical properties to ensure consistent performance and batch-to-batch uniformity. Certificates of Analysis (COA) documenting full specifications are available upon request to support your quality assurance protocols.

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/59-77°F). Protect from freezing and extreme heat. Keep away from strong oxidizing agents. For long-term storage, maintain under an inert atmosphere if the product is supplied as a solid or in solvent to prevent skin formation or polymerization.
