Description

2-Propenoic Acid, 2-Methyl-, Methyl Ester, Polymer With Ethenylbenzene And Ethyl 2-Propenoate is a high-performance, multi-component acrylic copolymer designed for demanding industrial applications. This polymer's unique composition provides an exceptional balance of durability, chemical resistance, and film-forming properties. It is a critical raw material for formulators in the coatings, adhesives, and specialty plastics industries seeking to enhance product performance.

Application

• Industrial and Protective Coatings: Used as a key binder in high-performance paints and varnishes requiring excellent adhesion, gloss retention, and resistance to chemicals and weathering.
• Adhesives and Sealants: Serves as a primary polymer component in pressure-sensitive adhesives (PSAs), construction sealants, and laminating agents, offering strong bonding and flexibility.
• Printing Inks: Employed in the formulation of overprint varnishes and specialty inks to improve rub resistance, gloss, and drying characteristics.
• Textile and Leather Finishes: Acts as a coating or finishing agent to provide water repellency, abrasion resistance, and a desired hand feel to fabrics and leather goods.
• Plastic Modifiers: Utilized as an impact modifier or processing aid to enhance the toughness and surface characteristics of thermoplastic compounds.

Quality Control

Every batch of our acrylic copolymer is manufactured under a strict quality management system. We perform comprehensive analytical testing to ensure consistent molecular weight distribution, monomer content, and physical properties. A Certificate of Analysis (COA) detailing key parameters such as solids content, viscosity, glass transition temperature (Tg), and residual monomers is provided with each shipment to guarantee it meets your formulation requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from strong acids and organic solvents. For long-term storage, ensure containers are properly sealed to prevent moisture absorption or skin formation.
