Eastman CAP-482-20 is a high-viscosity powdered film-forming resin in the cellulose acetate propionate series, tailored for industrial scenarios such as coatings, inks and adhesives. As a white powder with 100% pure CAP composition, it has high melting point, excellent thermal stability,
Ultra - High Viscosity & Adaptability - Suitable for automotive primer and clear coat, meeting the requirements of high - viscosity systems and improving coating texture and stability
Drying Acceleration & Orientation Enhancement - Accelerate solvent volatilization to shorten touch - dry time, promote aluminum powder orientation and enhance metallic paint flash effect
Broad Compatibility & Stability - Miscible with acrylic, amino and other resins, improving system stability and inhibiting intercoat bleeding and lifting
Flexibility & Long - lasting Crack Resistance - Endow the paint film with excellent flexibility, yellowing resistance and cold crack resistance, ensuring long - term stable appearance of coatings for outdoor use
Automotive OEM/Refinish Primer - Promote primer shrinkage and aluminum powder orientation, and improve coating corrosion resistance and decorative performance
Automotive Clear Coat Systems - Enhance adhesion and gloss, improve gloss retention, and meet the needs of cross - linking and fast drying
High - end Metallic Coatings - Accelerate solvent release to shorten drying time, and enhance coating wear resistance and color stability
Plastic Protective Coatings - Improve flexibility and cold crack resistance, suitable for coating plastic casings of electronics, home appliances, etc
