Product Description
Eastman™ CAP-482-0.5 Cellulose Acetate Propionate 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. Eastman™ CAP-482-0.5 is lawful for use in certain food-contact applications subject to the food additive regulations of the FDA.
