摘要： PROBLEM TO BE SOLVED: To form a coating film having simultaneously improved plural properties by coating the top of a member for an iron structure with an epoxy resin powdery coating material and further coating it with a powdery coating material contg. a resin selected from among acrylic resin, hydroxyl group-contg. polyester resin, hydroxyl group-contg. fluororesin and epoxy resin as a binder component. SOLUTION: Pellets obtd. by mixing and kneading epoxy resin with a hardener such as a phenolic hardener having a bisphenol skeleton, a surface modifier and a pigment are comminuted to prepare a powdery coating material (A). Pellets obtd. by mixing and kneading the same epoxy resin with a hardener such as adipic dihydrazide, a hardening accelerator, a surface modifier and a pigment are comminuted to prepare a powdery coating material (C). A hot rolled steel sheet is heated to a prescribed temp. and electrostatically coated with the powdery coating material C. While the coating material C is in a molten state, the steel sheet is further electrostatically coated with the powdery coating material A. The coated steel sheet is then allowed to cool to form the objective coating film having simultaneously improved plural properties.

摘要： PROBLEM TO BE SOLVED: To obtain a powder coating material composition that occurs no coating defect, e.g. casing on a film surface of the coating material composition even when mixed with a powder coating material composition different in resin grade or a curing system, which is caused by changing the resin grade or the curing system when producing or coating the powder coating material composition. SOLUTION: This powder coating material composition comprises a thermosetting polyester resin having an acid value of 10-2500 mgKOH/g and bearing carboxyl terminals, an epoxy resin as a curing agent for the polyester resin having 50-2,500 epoxy equivalent and at least one acrylic resin selected from the group consisting of glycidyl group-containing acrylic resins and carboxyl group-bearing acrylic resins. In this case, the amount of the acrylic resin is 0.1-10 wt.% based on the powder coating material composition. COPYRIGHT: (C)2003,JPO
