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. |
