Eastman CAB-381-0.1 Cellulose Acetate Butyrate

Eastman CAB-381-0.1 is an ultra-low viscosity modified resin in the cellulose acetate butyrate series, specially designed for performance optimization of various coating systems. It features extremely low viscosity, can efficiently accelerate solvent release from paint films and greatly shorten drying time. The formed film is yellowing-resistant and crack-resistant, and it can enhance coating wear resistance and color stability

Features Of Eastman CAB-381-0.1 Cellulose Acetate Butyrate

  1. Ultra-low Viscosity - Easy to disperse and add in the system, no increase in coating system viscosity, suitable for high solid content coating formula design

  2. Fast Solvent Release & Drying - Accelerate the volatilization and release of solvent in the paint film, greatly shorten the touch and hard drying time, and improve the coating construction efficiency

  3. Yellowing & Crack Resistance - No yellowing of the paint film during long-term use, no cracking of the paint film in low temperature environment, ensuring the appearance stability of the coating

  4. Excellent Wear Resistance & Color Stability - Significantly enhance the surface wear resistance of the coating, prevent the paint film from being damaged by scratching

Typical Applications Of Eastman CAB-381-0.1 Cellulose Acetate Butyrate

  1. Metal Decorative & Protective Paint - Accelerate paint film drying, improve the wear resistance and gloss of metal paint, and keep the coating color lasting and stable

  2. Plastic Coating Modification - Enhance the flexibility and scratch resistance of plastic paint, prevent paint film cracking, and improve the coating quality of plastic parts

  3. Automotive OEM/Refinish Paint - Shorten the coating drying cycle, improve the weather resistance and yellowing resistance of the paint film, and adapt to the automotive coating process

  4. Wood Decorative Coating - Endow wood paint with excellent flexibility, prevent paint film cold cracking, and improve coating wear resistance and gloss
