Description

2-Propenoic Acid, Polymer With Butyl 2-Propenoate, Ethenylbenzene And 2-Propenenitrile CAS NO 25586-25-8 is a high-performance, multi-component acrylic copolymer designed for demanding industrial applications. This specialized polymer offers a unique balance of properties derived from its constituent monomers, including acrylic acid, butyl acrylate, styrene, and acrylonitrile. It is essential for formulators and manufacturers seeking to enhance the durability, adhesion, and chemical resistance of their products. Key industries that rely on this advanced material include coatings, adhesives, sealants, and construction chemicals.

Application

• Industrial and Protective Coatings: Used as a key binder or additive to improve film formation, weather resistance, and adhesion to various substrates like metal, concrete, and plastics.
• Adhesives and Sealants: Provides excellent cohesive strength, flexibility, and resistance to water and chemicals in pressure-sensitive adhesives (PSAs), construction sealants, and assembly adhesives.
• Textile and Leather Finishes: Serves as a durable coating or finishing agent to impart water repellency, stiffness, and abrasion resistance to fabrics and leather goods.
• Paper and Packaging Coatings: Enhances the surface strength, printability, and barrier properties of paperboard and packaging materials.
• Caulks and Joint Compounds: Improves application properties, crack resistance, and longevity in construction and automotive sealing applications.
• Specialty Binders: Acts as a robust binder in non-woven fabrics, fiberglass mats, and other composite materials requiring high performance.

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards and batch-to-batch consistency. Key parameters monitored include solid content, viscosity, pH, glass transition temperature (Tg), and monomer residue levels. Certificates of Analysis (COA) are available upon request, detailing the specifications for each production lot. We adhere to a robust Quality Management System to support our commitment to reliable supply and product performance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (typically 15-25°C). Avoid exposure to extreme heat or freezing conditions. Keep away from strong oxidizing agents. For long-term storage, ensure containers are properly sealed to prevent moisture absorption or skin formation.
