THERMOSETTING TYPE POWDER COATING MATERIAL AND THERMOSETTING POWDER COATING FILM FORMATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a powder coating film formation method excellent in a finished appearance.;SOLUTION: A characteristic of the powder coating film formation method is to form the coating film, by performing an electrostatic powder coating to a material to be coated so that a density of the powder coating, such as of a vinyl system resin powder coating material, a polyester system powder coating material, an epoxy system resin powder coating, material, becomes 40% or more, and then by heating for the film formation. Moreover, a characteristic of the powder coating film formation method is that a mean particle diameter of the powder of the coating material is 5 to 30 μm, a thermosoftening temperature of the powder coating material is 30 to 100°C, and the powder coating film thickness is 50 to 150 μm.;COPYRIGHT: (C)2003,JPO
