SheffCoat™ HS is a high strength film coating system provides increased film elasticity and adhesion to the core. Some tablets have softer cores and may need a very strong coat applied very quickly in order to ensure the tablet core does not erode during the coating process. There are also certain APIs that are extremely sensitive to moisture. SheffCoat™ HS combines HPMC with HPC to provided improved film characteristics to overcome these issues by providing increased film elasticity and adhesion.
- HPC adds film elasticity and adhesion
- HPC may also increase viscosity at higher usage rates, slightly lowering solids content of spray adhesion
