Slot die is a premetered coating operation in which the coating solution is extruded from a feed slot onto the surface of a substrate passing through. The defect-free region of operation is known as the “coating window”, and the wider it is, the more versatile the operation will be. The slot-coating experiments reported here were carried out with two types of coating solutions, a hard ... (PDF) Slot coating [microform] : fluid mechanics and die design Slot die coating is a pre-metered process commonly used for producing thin and uniform films. It is an important film fabrication method for applications where precise coating is required.
