#### Abstract

In this paper, we study the coating performance according to the slot-die conditions in the coating process. The quality of the slot-die coating depends on factors such as feeding speed of film, the viscosity of liquid, and the pressure applied to the slot-die. In this study, we determine the optimum conditions for a stable coating by performing 2-D and 3-D simulations. We carry out numerical simulations with respect to the feeding velocity of the film, the pressure of the slot-die inlet, and the viscosity of the coating liquid. Based on the results, the coating was the most reliable when the pressure of the inlet was $5kgf/cm^2$, the viscosity was about 100 cps and the velocity was 20 m/min.
