Description

2-Propenoic Acid, 2-Methyl-, Polymer With Ethenyl Acetate And Methyl 2-Methyl-2-Propenoate is a high-performance, multi-component acrylic copolymer designed for demanding industrial applications. This versatile polymer offers a unique balance of properties derived from its constituent monomers, including adhesion, film formation, and chemical resistance. It is an essential raw material for formulators in the coatings, adhesives, and construction chemical industries seeking to enhance product durability and performance.

Application

• Industrial and Architectural Coatings: Used as a key binder in water-based paints, primers, and topcoats to provide excellent adhesion, weather resistance, and film integrity.
• Adhesives and Sealants: Serves as a primary polymer in pressure-sensitive adhesives (PSAs), construction adhesives, and caulks, offering strong bonding and flexibility.
• Construction Chemicals: Incorporated into cement modifiers, tile adhesives, and waterproofing membranes to improve flexibility, water resistance, and substrate bonding.
• Textile and Non-Woven Binders: Acts as a durable binder for fiber bonding in non-woven fabrics and as a coating for textiles to impart stiffness or water repellency.
• Paper Coatings: Enhances the surface properties of paper, providing improved printability, gloss, and strength.
• Leather Finishing: Used in topcoat formulations for leather to provide a protective, flexible, and aesthetically pleasing finish.

Quality Control

Our acrylic copolymer is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent purity, molecular weight distribution, and performance characteristics such as viscosity, solids content, and acid value. We provide comprehensive Certificates of Analysis (COA) with every shipment, detailing all relevant specifications 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. For long-term storage, a nitrogen blanket is recommended to prevent skin formation or polymerization. Keep container tightly sealed when not in use to prevent moisture absorption and contamination.
