Description

2-Propenoic acid, 2-methyl-, polymer with ethenylbenzene, 2-ethylhexyl 2-methyl-2-propenoate, 2-hydroxyethyl 2-propenoate and 2-methylpropyl 2-methyl-2-propenoate CAS NO 65970-33-4 is a high-performance, multi-component acrylic copolymer designed for demanding industrial applications. This specialized polymer offers a unique balance of properties, including excellent adhesion, chemical resistance, and film-forming characteristics, making it a critical raw material for advanced coating systems. It is primarily utilized by formulators in the paints & coatings, adhesives & sealants, and industrial resin sectors seeking to enhance product durability and performance.

Application

• Industrial and Protective Coatings: A key binder in high-performance metal primers, topcoats, and corrosion-resistant paints for automotive, marine, and structural steel applications.
• Architectural Coatings: Used in exterior and interior paints to improve weatherability, scrub resistance, and adhesion to challenging substrates.
• Adhesives and Sealants: Serves as a base polymer for pressure-sensitive adhesives (PSAs), construction sealants, and industrial bonding agents, providing strong tack and cohesion.
• Printing Inks: Formulated into overprint varnishes and specialty inks to enhance gloss, rub resistance, and drying properties.
• Textile and Leather Finishes: Applied as a coating or binder to provide durable, flexible, and water-resistant finishes on fabrics and leather goods.
• Plastic and Wood Coatings: Improves surface hardness, appearance, and chemical resistance on plastic components and wooden furniture.

Quality Control

Our acrylic copolymer is manufactured under a strict quality management system. Each batch undergoes rigorous testing for critical parameters including solids content, viscosity, acid value, and glass transition temperature (Tg) to ensure batch-to-batch consistency and performance reliability. Certificates of Analysis (COA) documenting full specifications are available upon request. Our production adheres to relevant ISO 9001 standards, and the product is compliant with global regulatory frameworks such as 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). Do not freeze. Keep away from heat sources and open flame. Under these conditions, the product has a typical shelf life of 12 months from the date of manufacture.
