装がなし得なかった。However, by storing the paint in a paint tank, the solvent contained in the paint vaporizes and evaporates for a while, increasing the viscosity of the paint. Furthermore, the heat retained by the coating agent is carried away by the evaporation of the solvent, and the temperature of the solvent is lowered. Therefore, the viscosity of the coating material also increases as the temperature of the coating material decreases. As described above, the finish of the coating changes depending on the content of the solvent contained in the solvent and the temperature of the coating material, making it impossible to achieve a uniform coating.
