Description

2-Propenoic acid, 2-methyl-, polymer with butyl 2-propenoate, ethenylbenzene, 2-hydroxyethyl 2-methyl-2-propenoate, methyl 2-methyl-2-propenoate and 2-propenoic acid CAS NO 70714-91-9 is a specialized multi-component acrylic copolymer designed for high-performance applications. This polymer is engineered to deliver a precise balance of properties including adhesion, flexibility, and chemical resistance, making it a critical raw material for advanced formulations. It is essential for manufacturers in the coatings, adhesives, and specialty polymer industries seeking to enhance product durability and performance.

Application

• Industrial and Protective Coatings: Used as a key binder in high-performance metal, wood, and plastic coatings requiring excellent weather resistance and adhesion.
• Pressure-Sensitive Adhesives (PSAs): Serves as a primary component in tapes, labels, and graphic films, providing a tunable balance of tack, peel strength, and cohesion.
• Automotive Refinish and OEM Coatings: Imparts durability, gloss retention, and resistance to chemicals and environmental etching in automotive paint systems.
• Industrial Adhesives and Sealants: Formulated into construction adhesives, laminating adhesives, and sealants where strong bonding and flexibility are required.
• Printing Inks and Overprint Varnishes: Enhances the rub resistance, gloss, and substrate adhesion in flexographic and gravure inks for packaging.
• Textile and Leather Finishes: Applied as a coating or binder to provide water repellency, soft hand feel, and abrasion resistance to fabrics and leather goods.

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 testing for critical parameters including solids content, viscosity, acid value, glass transition temperature (Tg), and molecular weight distribution. Certificates of Analysis (COA) detailing all test results are provided and can be tailored to meet specific customer or regulatory requirements.

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 is typically stable for 24 months from the date of manufacture. Refer to the specific technical data sheet for detailed shelf-life information.
