Description

2-Propenoic Acid, Polymer With Ethenylbenzene, Ethyl 2-Propenoate And (1-Methylethenyl)Benzene CAS NO 68650-88-4 is a high-performance, multi-component acrylic copolymer designed for demanding industrial applications. This polymer offers a unique balance of properties, including excellent film formation, adhesion, and chemical resistance, making it a critical raw material for advanced coating systems. It is primarily utilized by formulators in the paints and coatings, adhesives, and specialty chemical industries seeking to enhance product durability and performance.

Application

• Architectural and Industrial Coatings: Used as a key binder in water-based and solvent-based paints to provide durability, gloss, and weather resistance.
• Adhesives and Sealants: Serves as a primary polymer component in pressure-sensitive adhesives (PSAs), construction adhesives, and sealants, offering strong bonding and flexibility.
• Industrial Maintenance Coatings: Formulated into protective coatings for metal, concrete, and other substrates to guard against corrosion, chemicals, and abrasion.
• Printing Inks: Acts as a resin in flexographic and gravure inks, contributing to print quality, adhesion on various substrates, and rub resistance.
• Textile and Leather Finishes: Employed in coatings and finishes to impart water repellency, softness, and improved handle to fabrics and leather goods.
• Paper Coatings: Used in barrier coatings and functional finishes to enhance paper strength, printability, and resistance to water and grease.

Quality Control

Our acrylic copolymer is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent performance and compliance with agreed specifications. Certificates of Analysis (COA) documenting key parameters such as solids content, viscosity, pH, and glass transition temperature (Tg) are provided with every shipment. We support compliance with global regulatory frameworks including REACH.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, 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 skin formation or changes in viscosity.
