Process evaporates organic solvent or aqueous vehicle as coating is applied. Fluid-bed process has greater drying capacity than other methods, due to high volume 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. Coating Place, Verona, WI.
