Description

2-Propenoic Acid, 2-Methyl-, Ethyl Ester, Polymer With Butyl 2-Propenoate And Methyl 2-Propenoate is a high-performance acrylic copolymer designed to deliver exceptional film-forming properties, adhesion, and durability. This versatile polymer is engineered to provide a critical balance of flexibility, chemical resistance, and weatherability for demanding industrial applications. It is an essential raw material for formulators in the coatings, adhesives, and sealants industries seeking to enhance product performance and reliability.

Application

• Industrial and Protective Coatings: Used as a primary binder in metal primers, machinery enamels, and corrosion-resistant topcoats.
• Architectural Coatings: Formulated into exterior paints and stains for wood, masonry, and other substrates, offering excellent UV resistance and durability.
• Adhesives and Sealants: Serves as a key component in pressure-sensitive adhesives (PSAs), construction sealants, and laminating adhesives, providing strong bonding and flexibility.
• Automotive Refinish: Incorporated into basecoats and clearcoats for automotive refinishing applications, delivering a high-gloss finish and resistance to chemicals and environmental exposure.
• Plastic Coatings: Applied as a coating for plastic components in consumer electronics and automotive interiors to improve scratch resistance and aesthetic appeal.
• Textile and Leather Finishes: Used in coatings and binders for textiles and synthetic leather to impart water repellency, abrasion resistance, and a soft hand feel.
• Printing Inks: Acts as a resin for overprint varnishes and specialty inks, enhancing gloss, rub resistance, and drying properties.

Quality Control

Our acrylic copolymer is manufactured under a strict quality management system to ensure batch-to-batch consistency and performance. Each lot is tested against stringent in-house specifications for critical parameters such as solids content, viscosity, glass transition temperature (Tg), and residual monomers. Certificates of Analysis (COA) detailing these results are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at temperatures between 15-25°C (59-77°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.
