HIGHLY SMOOTH COATING COMPOSITION THAT CAN REALIZE FILM OF LOW SURFACE ROUGHNESS, APPLICATION METHOD AND REPAIR METHOD THEREFOR, AND COMPRESSOR SURFACE-TREATED WITH THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a coating composition that can realize a film having excellent surface smoothness and heat resistance.;SOLUTION: A coating composition is used for forming a top coat layer on a surface of a substrate. When a surface roughness of the substrate is Ra1, and a surface roughness of a film composed of the coating composition formed on the surface of the substrate is Ra2, Ra2/Ra1 is 0.4 or less.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2018,JPO&INPIT
