METHOD OF FORMING COATING FILM

摘要

PROBLEM TO BE SOLVED: To provide a method of forming a coating film by which the coating film free from coating unevenness such as coating stripes or repelling is obtained in a dip coating method of forming the coating film on a material to be coated by suspending the material to be coated in a coating vessel and dipping into a coating liquid filled in the coating vessel. SOLUTION: In the method of forming the coating film by suspending the material to be coated in the coating vessel and dipping into the coating liquid filled in the coating vessel to form the coating film on the material to be coated, the dipping time of the material to be coating into the coating liquid satisfies the following inequality. 3a+b>80 (sec)...(1) In the inequality, (a) is the time required until the material to be coated moves downward up to a prescribed position and stops after the material to be coated is brought into contact with the liquid surface of the coating liquid and (b) is the time while the material to be coated is suspended in the coating liquid.
