Eastman Cellulose Acetate Butyrate (CAB-381-0.5) is a cellulose ester with medium butyryl content and low viscosity. It was designed for use where low-application viscosities at relatively high solids levels is needed. It is soluble in a wide range of solvents and compatible with many other resins. When CAB-381-0.5 is dissolved in appropriate solvents a clear, colorless solution is produced. It will also tolerate the use of solvent blends currently exempt from certain air pollution regulations. It is supplied as a dry, free-flowing powder.
Eastman CAB-381-0.5 is based on cellulose, one of the most abundant natural renewable resources, from trees harvested from sustainably managed forests.
