Slot-die coating is an extremely versatile deposition technique that is capable of being integrated into both roll-to-roll and sheet-to-sheet deposition systems. A major advantage of slot-die coating is its simple relationship between wet-film coating thickness, the flow rate of solution, and the speed of the coated substrate relative to the head. Wetting behavior of the shear thinning power law fluids ... The knowledge of the wetting characteristics of a coating solution is a prerequisite of assuring the final quality of thin films manufactured by the slot die coating process. Because the maximum coating speed is limited by defects, such as air entrainment, which are directly related to film quality, an understanding of the coating limits is ... Slot-Die Coating: Theory, Design, & Applications – Ossila Slot-die coating, with its ability to coat across a wide range of viscosities and at high web speeds, means that the technique can be used for advanced thin-film manufacturing and also for low-cost, high-volume products. A wide variety of products use slot-die coating as a thin-film deposition method, including: Coating and Casting Defect-Free Films
