In the Slot Die process, the coating is pressed out by gravity or under weight through a slot and onto the substrate. In the event that the coating is 100% solids, the process is termed "Extrusion" and for this situation, the line velocity is regularly much speedier than the rate of the extrusion. This empowers coatings to be significantly more slender than the width of the slot. Slot Die Coating is a repeatable, solid coating strategy that keeps on gaining support in a mixed bag of coating.
