KOLLIDON® VA 64
Copovidone USP/NF, EP, JPE Kollidon VA 64 is a vinylpyrrolidone - vinyl acetate copolymer in a ratio of 6:4 (by mass) that is soluble in water and alcohol. This product strongly improves dry binding capacity. Due to its high plasticity, distinguishing it from povidone (Kollidon 30), it produces granules and mixtures that are less susceptible to capping and tablets that are less brittle.
