Description

2-Propenoic Acid, 2-Methyl-, Methyl Ester, Polymer With 2-Ethylhexyl 2-Propenoate And 2-Propenoic Acid is a high-performance acrylic copolymer designed for demanding industrial applications. This specialized polymer offers a unique balance of properties, including excellent film formation, adhesion, and chemical resistance. It is a critical raw material for formulators in the coatings, adhesives, and sealants 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.
• Adhesives and Sealants: Serves as a primary polymer in pressure-sensitive adhesives (PSAs), construction sealants, and laminating adhesives for its strong bonding and flexibility.
• Textile and Leather Finishes: Employed in coatings and binders to provide water resistance, durability, and a soft hand feel to fabrics and leather goods.
• Paper and Packaging Coatings: Enhances the gloss, printability, and water resistance of paperboard and packaging materials.
• Caulks and Putties: A vital component in formulations requiring excellent adhesion to diverse substrates and long-term elasticity.
• Specialty Inks: Used in flexographic and gravure ink formulations to improve adhesion on non-porous surfaces like plastics and foils.

Quality Control

Our production of this acrylic copolymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as monomer content, molecular weight distribution, viscosity, and acid value are rigorously monitored. Certificates of Analysis (COA) detailing all relevant specifications are 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 room temperature (15-25°C). Keep away from heat sources and open flames. For long-term storage, an inert atmosphere (e.g., nitrogen) is recommended to prevent oxidation and maintain product stability.
