Technical Data Sheet
Eastman™ Cellulose Acetate (CA-398-10)


Applications
  • Auto OEM
  • Auto refinish

Product Description

Eastman Cellulose Acetate CA-398-10 is a low viscosity solution grade of cellulose acetate. When CA-398-10 is dissolved in appropriate solvents a clear, colorless solution is produced.

Eastman CA-398-10 is based on cellulose, one of the most abundant natural renewable resources. The calculated approximate bio-content value of 55% for Eastman CA-398-10 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.
