Description

2-Propenoic Acid, 2-Methyl-, Polymer With Butyl 2-Propenoate, Methyl 2-Methyl-2-Propenoate And 2-Methyl-2-Propenamide is a high-performance, multi-component acrylic copolymer designed for demanding industrial applications. This polymer offers a unique balance of properties, including excellent film formation, adhesion, and chemical resistance, making it a versatile raw material for advanced coating systems. It is primarily utilized by formulators in the paints & coatings, adhesives, and specialty chemical industries seeking to enhance product durability and performance.

Application

• Industrial and Protective Coatings: Used as a key binder in metal primers, automotive underbody coatings, and corrosion-resistant finishes.
• Architectural Paints: Serves as a film-forming agent in exterior and interior wall paints, providing weatherability and scrub resistance.
• Adhesives and Sealants: Imparts strong adhesion and flexibility in pressure-sensitive adhesives (PSAs), construction sealants, and laminating agents.
• Textile and Leather Finishes: Applied as a coating or binder to provide water repellency, abrasion resistance, and improved hand feel.
• Paper and Packaging Coatings: Enhances surface gloss, printability, and barrier properties in coated papers and paperboard.
• Specialty Inks: Formulated into overprint varnishes and ink vehicles to improve gloss, rub resistance, and drying characteristics.

Quality Control

Our acrylic copolymer is manufactured under a strict quality management system. Each batch undergoes rigorous testing for critical parameters such as solids content, viscosity, pH, and glass transition temperature (Tg) to ensure consistent performance and batch-to-batch uniformity. Certificates of Analysis (COA) detailing all test results are provided and available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C/59-77°F). Keep away from heat sources and open flame. For long-term storage, ensure containers are properly sealed to prevent skin formation or changes in viscosity.
