Fundamentals of Slot Coating Process - AIMCAL

The effect of bead vacuum on the minimum wet thickness obtained on horizontal and vertical slot die coatings was experimentally examined using a flow visualization technique. The commercial software package FLOW3D was used to simulate the two-dimensional coating flow. Macroscopic material balances were applied to estimate the effect of bead vacuum.

It is possible to define the flowing behaviour through the slot-die by adding the coating liquid density, the working width, the gap between the slot-die and substrate speed with the equation . In this equation m describes the mass flow, U w the substrate velocity, B the coating width, h the wet film thickness and p the density. Comparison of vertical and horizontal slot die coatings ... In the present study, experiments are carried out to examine the difference between vertical and horizontal slot die coatings. The minimum wet thicknesses as well as the photographic images of coating bead under different coating conditions are presented for each case. Minimum wet thickness for double-layer slide-slot coating of ... The operating coating windows were examined as a function of flow rates and viscosities of the two coating layers. The top coating layer could be made much thinner as compared to the double-layer coating so long as a stable thin film could be formed on the slide. A minimum wet thickness of the top layer was found to be as thin as 5 μm or less.
