Description

Poly(n-Butyl Acrylate/Acrylic Acid) is a synthetic copolymer of n-butyl acrylate and acrylic acid, widely recognized by its CAS number 25119-83-9. This versatile polymer is engineered to provide a unique balance of flexibility, adhesion, and acid functionality, making it a critical raw material for advanced formulations. It is essential for manufacturers in the adhesives, coatings, textiles, and specialty chemical industries seeking to enhance product performance through tailored polymer chemistry.

Application

• Pressure-Sensitive Adhesives (PSAs): A key component for formulating high-performance acrylic-based PSAs, offering excellent tack, peel strength, and aging stability for tapes and labels.
• Industrial & Architectural Coatings: Used as a film-forming agent and binder to improve flexibility, water resistance, and adhesion of coatings on various substrates.
• Textile Finishing & Nonwovens: Serves as a durable binder and modifier for textile coatings, providing softness, wrinkle resistance, and fiber cohesion.
• Printing Inks & Overprint Varnishes: Enhances gloss, rub resistance, and substrate adhesion in flexographic and gravure ink systems.
• Leather Finishing: Imparts desirable softness, flexibility, and a protective finish to leather goods.
• Caulks & Sealants: Acts as a polymeric plasticizer and adhesion promoter, improving flexibility and long-term durability.
• Paper Coating: Used to improve the surface strength, printability, and gloss of high-quality paper products.
• Specialty Chemical Intermediates: The carboxylic acid groups provide reactive sites for further chemical modification, enabling use in cross-linking systems and advanced polymer synthesis.

Quality Control

Our Poly(n-Butyl Acrylate/Acrylic Acid) is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent composition, molecular weight distribution, acid value, and physical properties. Certificates of Analysis (COA) detailing key specifications such as solids content, viscosity, pH, and glass transition temperature (Tg) are available upon request 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, an inert atmosphere (e.g., nitrogen) is recommended to prevent oxidation or moisture absorption, which could affect polymer properties.
