Hot Melt Coating applies a molten material, like polymers or waxes, to a substrate, which solidifies upon cooling to form a protective layer. Process Overview It involves heating the coating material to a low-viscosity melt, spraying or extruding it onto particles or surfaces (e.g., in a fluidized bed coater), and allowing rapid solidification without solvents. This solvent-free method avoids drying times, making it faster and more efficient than traditional coatings.
