Eastman cellulose acetate propionate (CAP-504-0.2)

<P>Eastman cellulose acetate propionate (CAP-504-0.2) is a free-flowing powder having low odor, low color, and high hydroxyl content. It is fast dissolving, has good water tolerance and resistance to souring, and is compatible with many ink resins and solvents. It has good resistance to discoloration from UV light and has good adhesion to plastics. It has a low viscosity (0.2 seconds) and has an approximate propionyl content of 42.5 wt%. When CAP-504-0.2 is dissolved in appropriate solvents, a clear, colorless solution is produced.</P><P>Eastman CAP-504-0.2 is based on cellulose, one of the most abundant natural renewable resources. The calculated approximate bio-content value of 49% for Eastman CAP-504-0.2 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.</P><P> For applications that require food contact compliance, please refer to Eastman CAP-504-0.2, food contact.</P>
