The thickness of the coatings currently used varies widely, and some coatings are very thin, and the surface is required to be uniform and smooth. In order to improve production capacity, the coating speed must be high, so some research institutions began to study micro-gravure roll coating and slot coating. Micro-gravure roll coating has the advantages of easy operation, wide coating range, saving substrate, wide adaptation range of substrate thickness, good coating appearance, smooth and shiny surface. Slot coating is a predictive coating method with uniform coating, which can realize large-scale coating and ultra-thin coating. These two coating methods are new precision coating technology developed after precision coating technology such as multi-layer slope extrusion coating and falling curtain coating. They are gradually used in flat panel displays, optoelectronic products, and lithium batteries And other related products.
