The compound, identified by CAS No. 25951-38-6, is supplied with consistent quality to meet global manufacturing standards.

Application

• Industrial and Protective Coatings: Used as a film-forming agent in metal primers, automotive topcoats, and corrosion-resistant paints for excellent weatherability and gloss retention.
• Architectural Paints: Serves as a key binder in exterior and interior wall paints, providing scrub resistance, adhesion to various substrates, and low-temperature film formation.
• Pressure-Sensitive Adhesives (PSAs): Imparts tack, peel strength, and shear resistance in labels, tapes, and graphic films.
• Industrial Adhesives & Sealants: Enhances bonding strength and flexibility in construction sealants, assembly adhesives, and laminating agents.
• Textile and Leather Finishes: Applied as a coating or binder to provide water repellency, abrasion resistance, and improved hand feel.
• Paper and Packaging Coatings: Used to create barrier coatings, improve printability, and provide gloss for high-quality packaging materials.
• Ink Formulations: Acts as a resin vehicle in flexographic and gravure inks, contributing to adhesion, rub resistance, and drying properties.

Quality Control

Our acrylic copolymer is manufactured under a strict quality management system. Each batch undergoes rigorous testing for critical parameters including solids content, viscosity, glass transition temperature (Tg), acid value, and residual monomer levels to ensure batch-to-batch consistency and performance reliability. Certificates of Analysis (COA) documenting these specifications are available upon request. Production adheres to relevant ISO standards, and the product is compliant with global regulatory frameworks such as REACH.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). Avoid freezing and prolonged exposure to heat sources above 40°C (104°F). Keep away from strong oxidizing agents.
