Description

2-Propenoic Acid, 2-Methyl-, Butyl Ester, Polymer With Butyl 2-Propenoate And Methyl 2-Methyl-2-Propenoate is a high-performance acrylic copolymer designed for superior film formation and durability. This polymer is a critical raw material valued for its excellent adhesion, weatherability, and chemical resistance in demanding industrial formulations. It is essential for manufacturers in the coatings, adhesives, and sealants industries seeking to enhance product performance and longevity.

Application

• Industrial and Architectural Coatings: Used as a primary binder in water-based and solvent-based paints for metal, wood, and plastic substrates, providing excellent gloss, hardness, and outdoor durability.
• Pressure-Sensitive Adhesives (PSAs): Serves as a key component in adhesive tapes and labels, offering a balance of tack, peel strength, and cohesive strength.
• Textile and Leather Finishes: Imparts water resistance, flexibility, and a soft hand feel to fabrics and leather goods.
• Printing Inks: Enhances pigment binding, print clarity, and rub resistance in flexographic and gravure inks.
• Caulks and Sealants: Provides elasticity, adhesion, and long-term stability in construction and automotive sealant applications.
• Paper Coatings: Improves surface smoothness, printability, and water resistance of paper and paperboard.

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 monomer levels. A Certificate of Analysis (COA) documenting these results is provided with every shipment to support your quality assurance protocols.

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). Avoid freezing and prolonged exposure to extreme heat. Keep away from strong oxidizing agents.
