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.  |
