Our collection of ambient temperature slot die coating and fluid coating machines include flexible and fixed lip systems.

The document provides an overview of slot die coating technology, including its background, system components, techniques, and processes.

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

CURTAIN COATING • Multi-layer coating o 2-3 layers in typical slot die design o Slide die design accommodates more layers o Separate fluid delivery system for each layer o Combined outside the slot exit σtop < σbottom (surface energy stability).
