Description

2-Propenoic Acid, 2-Methyl-, Polymer With Butyl 2-Propenoate, Ethenylbenzene And Ethyl 2-Propenoate, Bis(1-Methyl-1-Phenlethyl) Peroxide-Initiated is a high-performance, multi-component acrylic copolymer designed for demanding industrial applications. This specialized polymer offers a unique balance of properties, including excellent film formation, adhesion, and chemical resistance, making it a critical raw material for advanced coating systems. It is primarily utilized by formulators in the paints and coatings, adhesives, and construction materials industries seeking to enhance product durability and performance.

Application

• Architectural and Industrial Coatings: As a key binder in water-based or solvent-based paints, providing weatherability, gloss, and adhesion to various substrates.
• Protective and Marine Coatings: Formulating high-durability coatings that offer resistance to corrosion, chemicals, and UV degradation.
• Adhesives and Sealants: Serving as a primary polymer component in pressure-sensitive adhesives (PSAs), construction sealants, and laminating adhesives for strong, flexible bonds.
• Industrial and Automotive Finishes: Used in primers, topcoats, and clearcoats requiring excellent surface hardness, scratch resistance, and aesthetic appeal.
• Textile and Leather Finishes: Acting as a coating or binder to provide fabrics and leather with water repellency, stiffness, or a desired hand feel.
• Paper and Packaging Coatings: Enhancing the surface properties of paperboard and packaging materials for improved printability, gloss, and barrier resistance.

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 solid content, viscosity, acid value, glass transition temperature (Tg), and molecular weight distribution are rigorously monitored. A comprehensive Certificate of Analysis (COA) detailing all relevant specifications is 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 temperatures between 15-25°C (59-77°F). Keep away from heat sources and open flame. For long-term storage, ensure the container is kept sealed to prevent skin formation or changes in viscosity.
