Product Description

Eastman™ Cellulose Acetate Propionate CAP-482-0.5 is a low-odor, free-flowing powder. It is especially adaptable for use in printing inks and clear overprint varnishes because of its wide solubility in ink solvents, compatibility with other resins used in printing inks, and high melting point. Films formed from Eastman CAP-482-0.5 have fast solvent release, excellent antiblocking properties, and grease resistance superior to that of other film-formers. Its solubility and hardness make CAP-482-0.5 an excellent resin for nail lacquer topcoats. It is often used in combination with Eastman CAP-482-20 to optimize the formulation viscosity. When CAP-482-0.5 is dissolved in appropriate solvents a clear, colorless solution is produced.

Eastman CAP-482-0.5 is based on cellulose, one of the most abundant natural renewable resources. The calculated approximate bio-content value of 45% for Eastman CAP-482-0.5 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.
