Eastman CAP-482-20 is a cellulose ester with a high propionate level and high viscosity. Cellulose acetate propionates (CAPs) are highly soluble and have good compatibility with most common resins. They provide the durability of cellulose acetate and the flexibility and solubility of cellulose acetate butyrate. Thus, they are viewed as intermediate options in terms of properties and chemical structure within Eastman's cellulose ester portfolio.

CAP-482-20 is commonly used as a film former, resin modifier, and additive in inks, OPVs, and plastic and paper coatings. Unlike cellulose acetate butyrate (CAB), Eastman CAP-482-20 is virtually odorless. This makes it preferred over CABs in inks, OPVs, and paper coatings used in packaging. Adding CAP-482-20 to a coating or ink improves leveling, dry-to-touch time, durability, gloss, and UV stability. CAP-482-20 is commonly blended with CAP-482-0.5 to achieve proper viscosity.
