Wurster coating Company uses Wurster fluid-bed coating (micro-encapsulation) to apply films to powders, granules, and crystals ranging in diameters from 20 microns to several cen- timeters. Process evaporates organic solvent or aqueous vehicle as coating deposits. Fluid-bed process has greater drying capacity than other methods due to high vol- ume of fluidizing air that circulates particles and evaporates coating vehicle. Higher drying capacity translates into more efficient film application. Applications include hydrophilic coating of hydrophobic cores and water-based coating of water-soluble cores. Company optimizes film properties and/or product performance by changing coating formulation, processing conditions, or applying multiple layers. Process can also apply hot-melt coatings, such as wax. Other services include feasibility studies, formulation development, analytical lab support, process validation, scale-up, and technology transfer. The Coating Place, Verona, WI.
