Description

2-Propenoic acid, 2-methyl-, polymer with butyl 2-methyl-2-propenoate, 2-ethylhexyl 2-propenoate, 2-hydroxyethyl 2-methyl-2-propenoate and methyl 2-methyl-2-propenoate is a high-performance, multi-component acrylic copolymer designed to deliver a balanced profile of properties. This versatile polymer is engineered to provide excellent film formation, adhesion, and durability, making it a critical raw material for advanced coating formulations. It is essential for manufacturers in the paints & coatings, adhesives, and industrial sealants sectors seeking to enhance product performance and reliability.

Application

• Architectural and Decorative Paints: Serves as a key binder providing weatherability, scrub resistance, and excellent film integrity for interior and exterior coatings.
• Industrial Maintenance Coatings: Used in protective coatings for metal, concrete, and other substrates, offering corrosion resistance and durability in harsh environments.
• Adhesives and Sealants: Functions as a primary polymer in pressure-sensitive adhesives (PSAs), construction sealants, and assembly adhesives, providing strong adhesion and flexibility.
• Wood Finishes and Varnishes: Imparts clarity, hardness, and resistance to yellowing in clear coatings and topcoats for furniture and flooring.
• Textile and Leather Coatings: Applied as a finishing agent to provide water repellency, abrasion resistance, and a soft hand feel.
• Printing Inks: Utilized as a resin component to improve gloss, adhesion to various substrates, and rub resistance in packaging and commercial inks.

Quality Control

Our acrylic copolymer is manufactured under a strict quality management system. Each batch undergoes rigorous testing for critical parameters including solids content, viscosity, pH, and glass transition temperature (Tg) to ensure consistent performance and batch-to-batch uniformity. Certificates of Analysis (COA) documenting full specifications are available upon request 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 room temperature (15-25°C). Keep away from heat sources and open flame. Prevent freezing. Under these conditions, the product has a typical shelf life of 12 months from the date of manufacture.
