ABSTRACT:
Provision of two or more powder coatings different in hue, lightness and/or saturation as base colors makes it possible to mix the base color powder coatings in accordance with a desired color and hence to conduct color matching upon performing powder coating. It is therefore no longer necessary to stock a large number of powder coatings, in other words, it is therefore possible to systematically produce fewer powder coatings in greater quantities. This can achieve rationalization in production, storage, physical distribution, management and the like and also a cost reduction in each of these stages. For example, coatings of desired color tones, especially coatings excellent in artistry can be formed in accordance with a fluidized-bed, electrostatic coating process making use of a powder-fluidizing container by preparing in advance only three primary colors of yellow, red and blue or optionally five primary colors additionally including black color and white color. The present invention provides these powder coatings, powder coating process and powder-coated article.
