Eastman CAB-381-2 is a medium-viscosity modified resin in the cellulose acetate butyrate series, specially designed for weather resistance and application performance optimization of high-performance coating systems. It has excellent weather resistance and UV resistance, good miscibility with various resins, can accelerate solvent release to shorten drying time, improve leveling to prevent sagging, endow the paint film with high flexibility and yellowing resistance, enhance coating wear resistance and adhesion
Medium Viscosity & Wide Adaptability - Suitable for various coating systems, convenient application and easy dispersion, balancing system viscosity and film-forming performance
Excellent Weather Resistance & UV Resistance - No yellowing or cracking during long-term outdoor use, UV aging resistance, ensuring long-term stable coating appearance
Efficient Drying & Leveling - Accelerate solvent volatilization to shorten touch-dry time, optimize leveling and effectively prevent paint film sagging
Broad Compatibility & Adaptability - Miscible with acrylic, amino and other resins, improving system stability and inhibiting intercoat bleeding
Automotive OEM/Refinish Paint - Improve weather resistance and yellowing resistance, optimize leveling and polishability, suitable for clear coat and color coat systems
Plastic Coating Field - Enhance toughness and wear resistance, improve color stability, suitable for plastic casings of electronics, home appliances, etc
Wood Decorative Coating - Optimize drying and leveling, yellowing and crack resistance, improve coating gloss and hand feel
Printing Ink Applications - Improve leveling and adhesion, enhance color development, suitable for gravure, screen and other printing processes
