| Ossila.
Slot die coating is an extremely versatile deposition technique in which a solution is delivered onto a substrate via a narrow slot positioned close to the surface. A major advantage of
the slot die coating method is the simple relationship between wet-film coating thickness, the flow rate of solution, and the speed of the coated substrate relative to the head. In addition, slot die coating is capable of achieving extremely uniform films across large areas. The Ossila Slot Die Coater, for example, can produce coatings with variations lower than 5% across many meters and a variation of < 50 μm variation over 100 mm (0.05%). Slot die coating is one of many methods that can be used to deposit a thin liquid film onto the surface of a substrate. One of the main advantages of slot die coating over traditional
