![]() Slot die coating is one of many methods that can be used to deposit a thin liquid film onto the surface of a substrate. 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%). In addition, slot die coating is capable of achieving extremely uniform films across large areas. 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.Ī 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. ![]() Slot Die Coating: Theory, Design, & Applications ![]()
