After performing the coating operation, the concentration of the remaining stripping agent solution was measured and found to be 12.8% by weight, which was concentrated due to the scattering of the solvent, resulting in a large change in concentration.
Further, the coating thickness also varied widely, ranging from 5.7 to 10.5 μm. In this case, the length of the liquid tank is
The one used was 40 cm wide, 15 cm wide, and 15 cm deep, with an opening at the top.
