COATING FILM FORMING METHOD

摘要

PURPOSE: To provide a method capable of accurately and easily forming a coating film corresponding to each target dry film thickness an article to be coated with different film thickness requirements according to the coating region of a ship or the like and capable of forming a coating film having no hue difference in different film thicknesses. CONSTITUTION: An extender pigment, which contains 0.01-3 volume % of color pigment with respect to a paint solid component and contains an extender pigment with a whiteness of 85 or more, is used as a film thickness judging paint and the contents of the color pigment and the extender pigment are adjusted so as to satisfy (a) the color difference between the film thickness judge paint and the article to be coated is 20 or more, (b) the hue difference between the target dry film thickness and a coating film with a drying film thickness of < (target dry film thickness - 50) μm is 2 or more and (c) the hue difference between the coating film with the target dry film thickness and the coating film with a dry film thickness of > (target dry film thickness + 50) μm is below 1.
