Description

2-Propenoic Acid, 2-Methyl-, Polymer With Butyl 2-Methyl-2-Propenoate, Ethenylbenzene, 2-Ethylhexyl 2-Propenoate 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, including excellent adhesion, chemical resistance, and film-forming characteristics. It is a critical raw material for formulators in the coatings, adhesives, and specialty chemical sectors seeking to enhance product durability and performance.

Application

• Industrial and Protective Coatings: Used as a key binder in high-durability paints, metal primers, and anti-corrosion coatings for automotive, marine, and structural steel applications.
• Adhesives and Sealants: Serves as a primary polymer in pressure-sensitive adhesives (PSAs), construction sealants, and industrial bonding agents, providing strong tack and cohesion.
• Textile and Leather Finishes: Employed in coatings and finishes to impart water resistance, flexibility, and improved handle to fabrics and leather goods.
• Paper and Packaging Coatings: Enhances the surface properties, printability, and moisture barrier characteristics of paperboard and packaging materials.
• Plastic Modifiers and Additives: Functions as an impact modifier, processing aid, or compatibilizer in various plastic compounds to improve mechanical properties.
• Specialty Inks: Formulated into flexographic and gravure inks for packaging, providing excellent adhesion to non-porous substrates like films and foils.

Quality Control

Our production of this acrylic copolymer adheres to strict quality management systems, ensuring batch-to-batch consistency for formulators. Key parameters such as solid content, viscosity, acid value, glass transition temperature (Tg), and molecular weight distribution are rigorously monitored. Certificates of Analysis (COA) detailing all relevant specifications are provided with each 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 strong acids, organic solvents, and incompatible materials. For long-term storage, ensure containers are sealed to prevent skin formation or moisture uptake.
