Description

2-Propenoic acid, 2-methyl-, polymer with butyl 2-propenoate, ethenylbenzene, 2-hydroxyethyl 2-methyl-2-propenoate, (1-methylethenyl)benzene and methyl 2-methyl-2-propenoate CAS NO 125302-15-0 is a high-performance, multi-component acrylic copolymer designed to deliver exceptional durability and versatility. This polymer is engineered to provide a robust combination of film-forming properties, adhesion, and chemical resistance, making it a critical raw material for advanced industrial formulations. It is primarily utilized by manufacturers in the coatings, adhesives, and specialty chemical industries seeking to enhance product performance and longevity.

Application

• Industrial and Protective Coatings: Used as a primary binder in high-performance paints, metal coatings, and anti-corrosive primers, offering excellent weatherability and substrate adhesion.
• Adhesives and Sealants: Serves as a key component in pressure-sensitive adhesives (PSAs), construction sealants, and laminating adhesives, providing strong bonding and flexibility.
• Automotive Finishes: Formulated into clear coats and basecoats for automotive refinishing and OEM applications, delivering gloss retention and scratch resistance.
• Textile and Leather Finishes: Applied as a coating or binder to impart water repellency, durability, and a soft hand feel to fabrics and leather goods.
• Printing Inks: Enhances the performance of overprint varnishes and flexographic/gravure inks, improving gloss, rub resistance, and drying time.
• Plastic and Composite Modification: Acts as a modifier or impact modifier to improve the surface characteristics and mechanical properties of plastic composites.

Quality Control

Our production of this acrylic copolymer adheres to stringent quality management systems to ensure batch-to-batch consistency and performance reliability. Each lot undergoes comprehensive analysis, including tests for molecular weight distribution, solids content, viscosity, and glass transition temperature (Tg). Certificates of Analysis (COA) documenting full specifications are provided with every shipment. We support compliance with relevant global regulatory frameworks, including REACH.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). Keep away from heat sources and open flame. For long-term storage, ensure containers are sealed to prevent skin formation or changes in viscosity.
