Description

2-Propenoic Acid, 2-Methyl-, 1,2-Ethanediyl Ester, Polymer With 1-Ethenyl-4-Methylbenzene, 2-Ethylhexyl 2-Propenoate And 2-Methylpropyl 2-Methyl-2-Propenoate is a specialized multi-component acrylic copolymer designed to deliver a balanced profile of performance characteristics. This polymer is engineered to provide excellent adhesion, durability, and film-forming properties, making it a critical raw material for advanced coating and adhesive formulations. It is primarily utilized by manufacturers in the paints & coatings, pressure-sensitive adhesives, and industrial sealants sectors seeking to enhance product performance and reliability.

Application

• High-Performance Industrial Coatings: Used as a key binder in metal, wood, and plastic coatings requiring superior weather resistance, gloss, and chemical durability.
• Pressure-Sensitive Adhesives (PSAs): Serves as a primary polymer for labels, tapes, and graphic films, offering a balance of tack, peel strength, and shear resistance.
• Architectural Paints: Formulated into exterior and interior paints to improve scrub resistance, color retention, and overall film integrity.
• Industrial Sealants and Caulks: Provides flexibility, adhesion, and longevity in construction and automotive sealant applications.
• Printing Inks: Used in overprint varnishes and ink formulations to enhance gloss, rub resistance, and substrate adhesion.
• Textile and Leather Finishes: Applied as a coating to impart water repellency, softness, and abrasion resistance to fabrics and leather goods.

Quality Control

Our production of this acrylic copolymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Each lot is tested against key parameters including monomer residue, molecular weight distribution, viscosity, and glass transition temperature (Tg). A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment to support your quality assurance and regulatory compliance needs.

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, an inert atmosphere (e.g., nitrogen) is recommended to prevent oxidation and maintain product stability.
