Cellulose Acetate Butyrate 551-0.2 for automotive coatings

Cellulose Acetate Butyrate(CAB) can serve as a binder for protective and decorative coatings on metals, wood, textiles, fabrics, paper, plastics, and leather. It is a widely used additive in the coatings industry.

 CAB exhibits characteristics such as non-yellowing, flexibility, cold resistance, good color retention, excellent flow properties, resistance to hydrolysis, and high transparency.

It significantly improves coating flow, eliminates film shrinkage, enhances solvent release, promotes pigment dispersion, improves adhesion, and increases coating hardness. 

Typical Properties:

Remark:

1. Viscosity to be tested by Ubbelohde viscometer 0.24mm

2. Solution to test color and haze: 20% CAB 80% Ethyl Acetate .

3. To measure Color number by Pt-Co color scale, and to measure Haze by turbidimeter.

Application:

Automotive OEM, Coatings, Coatings for Automotive Plastics, Coatings for automotive, Coatings for plastic, Nail care, Truck/Bus/Commercial Vehicles
