Kollidon® VA 64 is a vinylpyrrolidone-vinyl acetate copolymers. It is used as dry binders for direct compression tableting, as granulating agents, as retarding and as a film-forming agents as well as in taste-masking applications. As copovidone with an exceptionally high binding capacity, Kollidon® VA 64 can be used as a dry binder for direct compression tableting and as a soluble binder for granulation. These properties make it an attractive and cost-effective alternative to natural binders. In addition, it is ideal as a solubilizer in hot-melt extrusion processes. Kollidon® VA 64 is especially suitable for markets with higher humidity exposure.
