Description

2-Propenoic Acid, Polymer With Butyl 2-Propenoate And 2-Propenenitrile is a high-performance acrylic-based copolymer designed for demanding industrial applications. This terpolymer combines the hardness and chemical resistance of acrylonitrile with the flexibility and adhesion properties of butyl acrylate and acrylic acid. It is essential for formulators seeking to create durable, versatile, and high-quality coatings, adhesives, and sealants. Key industries that rely on this polymer include paints and coatings, construction materials, textile finishing, and pressure-sensitive adhesives.

Application

• Industrial and Architectural Coatings: Used as a binder in water-based paints and varnishes to provide excellent film formation, durability, and weather resistance.
• Adhesives and Sealants: Serves as a key component in pressure-sensitive adhesives (PSAs) and construction sealants, offering strong adhesion and flexibility.
• Textile and Leather Finishing: Applied as a coating or binder to impart water repellency, stiffness, and abrasion resistance to fabrics and leather goods.
• Paper Coating: Enhances the strength, printability, and gloss of paper and paperboard products.
• Caulks and Fillers: Provides elasticity and adhesion in products used for sealing joints and gaps in construction.
• Non-Woven Binders: Acts as a binder for fibers in the production of non-woven fabrics for hygiene and filtration products.

Quality Control

Our production of 2-Propenoic Acid, Polymer With Butyl 2-Propenoate And 2-Propenenitrile adheres to stringent quality management systems to ensure batch-to-batch consistency and performance reliability. Each lot undergoes rigorous testing for critical parameters including solid content, viscosity, pH, glass transition temperature (Tg), and monomer residue levels. Certificates of Analysis (COA) documenting these specifications are available upon request, supporting your quality assurance and regulatory compliance needs.

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/59-77°F). Keep away from heat sources and open flame. To prevent skinning or premature polymerization, ensure containers are sealed when not in use. For long-term storage, maintain under an inert atmosphere if specified for the grade.
