Abstract:
A polymeric coating for a glass substrate includes a hexafluoropropylene oxide derived silane polymer. The hexafluoropropylene oxide derived silane polymer has a molecular weight of greater than about 5500, a thickness of between about 2 and about 15 nanometers and a coefficient of friction constant of less than about 0.35. A water contact angle of the polymeric hexafluoropropylene oxide derived silane coating decreases by less than about 27% after being subjected to 10000 abrasion cycles.
Abstract:
Provided is a method of forming an antifouling coating film including the steps of [1] preparing a colored antifouling paint containing a prescribed Si-containing hydrolyzable resin and a color pigment such that a coating film having a target dry film thickness T completely hides a surface of an object to be coated, the colored antifouling paint has a color difference ΔE1 between the coating film having the thickness T and a coating film having a dry film thickness of 0.8 T, at least 2.0, and preferably the colored antifouling paint has a color difference ΔE2 between the coating film having the thickness T and a coating film having a dry film thickness of 1.2 T, less than 1, and [2] coating a surface of the object with the colored antifouling paint until the surface of the object is completely hidden by the coating film formed from the colored antifouling paint.
