METHOD FOR FORMING ANTIFOULING COATING FILM

摘要

Provided is a method for forming an antifouling coating film. The method for forming an antifouling coating film includes [1] a step for preparing a colored antifouling coating material which includes a predetermined Si-containing hydrolysable resin and a colored pigment; a coating film formed from the colored antifouling coating material has a target dry film thickness and completely covers the surface of an article to be coated, the color difference (?E1) between a coating film having the target dry film thickness and a coating film having a dry film thickness of 0.8 T is 2.0 or greater, and preferably the color difference (?E2) between a coating film having the target dry film thickness and a coating film having a dry film thickness of 1.2 T is less than 1. The method for forming an antifouling coating film also includes [2] a step for coating the surface of the article to be coated, in which the surface of the article to be coated is coated with the colored antifouling coating material until the surface of the article to be coated is completely covered by a coating film formed from the colored antifouling coating material.
