APPLICATIONS

●Binder for tablets and granules Dry binder for direct compression Wet granulation	Sunvidone® VA is an excellent binder for tablets and granules. Between 2% and 5%, as a proportion of the final weight of the preparation, is usually used.
●Film-coating	Sunvidone® VA forms films that are soluble at all pH values.
●Subcoating	Sunvidone® VA is used in sugar-coating to improve the
●Sugar-coating	adhesion of the coating to the surface of the tablet core and to
●Sprays	increase the capacity of the coating solution for pigments and
●Controlled-release preparations	improve their dispersibility.
