Producer: 
Eastman
Eastman Cellulose Acetate Butyrate (CAB-321-0.1) is a cellulose ester with a low butyryl content (32.5%) and low molecular weight. It has a viscosity of 0.10 sec and 0.38 poise. Designed for use in automotive basecoats, it is resistant to attack and resistant to redisolve by solvents typical in clearcoats. When CAB-321-0.1 is dissolved in appropriate solvents a clear, colorless solution is produced. It is supplied as a fine white powder.Eastman CAB-321-0.1 is based on cellulose, one of the most abundant natural renewable resources, from trees harvested from sustainably managed forests. The calculated approximate bio-content value of 42% for Eastman CAB-321-0.1 was determined by using six bio-based carbon atoms per anhyroglucose unit divided by the total number of carbons per anhyroglucose unit. Although the value reported is not specifically measured for bio-carbon, it can be estimated based on typical partition data.
