CAP-504-0.2 has the highest hydroxyl level of the CAP range with a low viscosity. Cellulose acetate propionates (CAP) are highly soluble and compatibility with most resins. They have low odor and therefore recommended to use in inks, OPVs, plastic and paper coatings. Propionates are effective in dispersing pigments and stable to UV light. They do not react with dyes, fluorescent colors, or metallic pigments.
