Product Description

Eastman cellulose acetate propionate (CAP-482-20) is similar to Eastman CAP-482-0.5 in solubility and compatibility but Eastman CAP-482-20 has a higher viscosity. CAP 482-20 is useful as a film former in inks, overprint varnishes, and nail lacquer topcoats. It may be used alone or in combination with Eastman CAP-482-0.5. When CAP-482-20 is dissolved in appropriate solvents a clear, colorless solution is produced.

Eastman CAP-482-20 is based on cellulose, one of the most abundant natural renewable resources. The calculated approximate bio-content value of 43% for Eastman CAP-482-20 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.

For applications that require food contact compliance, please refer to CAP-482-20, Food Contact.
