A Review on Aqueous Film Coating Technology
Until about 1950, sugar coating was the first choice as coating agent for pharmaceutical preparation and much time & efforts were spent in perfecting the sugar coating techniques. Nobody ever was concerned about the problems like material cost, toxic effect due to coating or pollution etc. because the solvent used was always water. However, sugar coating technique was time consuming, affecting ...
متن کاملInfluence of Film Coating Process Parameters on the Gloss of Tablets Coated with Pigmented Aqueous Film Coating Formulations
Opadry® II 1 Influence of Film Coating Process Parameters on the Gloss of Tablets Coated with Pigmented Aqueous Film Coating Formulations PURPOSE A common practice for enhancing the gloss of coated tablets is the application of a clear top-coat after applying a pigmented coating layer. In a recent study, substantial increases in tablet gloss were achieved using this multiple step approach.1 It ...
متن کاملRoughness of 3C-SiC thin film coating computer simulation
This paper deals with efficiency of weakly ionized gas-wall interaction which leads to follows: melting surface, clustering of vapor and melted charged drops nucleation to the solid phase. It shapes roughness of the surface coating.
متن کاملNumerical Simulation of Film Formation in Tablet Coating
The application of a coating layer on a tablet is a commonly used technique to selectively control tablet characteristics. Among the most important functions of the coating is the regulation of the release of active ingredient. In the course of a typical coating process, the tablet passes a spray zone multiple times. Each time, a partial coating layer is applied. For each tablet, this is repeat...
متن کاملAntibacterial Performance of Alginic Acid Coating on Polyethylene Film
Alginic acid coated polyethylene films were examined in terms of surface properties and bacteriostatic performance against two most representative bacterial strains, that is, Escherichia coli and Staphylococcus aureus. Microwave plasma treatment followed by brush formation in vapor state from three distinguished precursors (allylalcohol, allylamine, hydroxyethyl methacrylate) was carried out to...
