Seal Coat System
Seal Coating System
Foundation Layer for Protection, Stability, and Functional Performance
COAT ICON® SE – Seal Coating System acts as a foundational layer that enhances tablet protection, stability, and overall functional performance. It forms a uniform, protective barrier over tablets, pellets, or granules, effectively safeguarding active ingredients from moisture, air, and environmental stress. This ensures that the product maintains its integrity and potency throughout its shelf life.
In addition to protection, COAT ICON® SE provides a smooth, reliable base for subsequent coatings, branding, or decorative finishes. Suitable for both pharmaceutical and nutraceutical formulations, it guarantees consistent quality, improves handling and packaging efficiency, and contributes to an enhanced consumer experience.
Seal Coat Range
Seal Coating: The First Layer of Tablet Protection
- Moisture Barrier – Prevents water-sensitive actives from degradation.
- Prevent Interaction – Minimizes interaction between core and coating materials.
- Smooth Surface – Improves tablet surface uniformity to ensure even coating.
- Enhance Adhesion – Improves adhesion of functional coatings.
- Dust Sealing – Binds fine particles on the tablet surface to reduce dusting ). It acts as a barrier between the tablet core and the subsequent coating layers.
- Minimizes interaction between active core and top layer.
- Reduces core erosion or friability during coating process.
