In the time series image below, the web is moved, and the slot coating die has two slots from which two different fluids issue. The advantage of the two-layer slot die is to reduce the number of die stations in the coating train. However, there are a number of challenges present in two-layer slot coating that do not exist in the single-layer case. Journal Publications – LMMP – PUC-Rio Journal Publications; ...

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 ...

A heterogeneous multiscale model for discrete cell gravure roll coating is presented along with experimental results for the purpose of model validation. The cell volume, generalized cell shape, and the gravure patterning are considered in the model which is based on a multiscale description of the flow in the coating bead.
