Eastman Cellulose Acetate Butyrate (CAB 381-0.1) 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 are needed. It is soluble in a wide range of solvents and compatible with many other resins. 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 cellulose esters are based on up to sixty percent cellulose, one of the most abundant natural renewable resources.

Determination of color and haze made on a solution of the cellulose ester dissolved in MIBK using Pt-Co color standards and Johns-Manville Celite (diatomaceous silica products) haze standards.
Polystyrene equivalent number average molecular weight determined by gel permeation chromatography.
Viscosity determined by ASTM Method D 1343. Results converted to poises (ASTM Method D 1343) using the solution density for Formula A as stated in ASTM Method D 817 (20% Cellulose ester, 72% acetone, 8% ethyl alcohol).
