Coating of organic and inorganic pigments with aldehyde or ketone resins, which contains a chemical compound consisting of particles of organic and inorganic solid substances, both defined as pigments, in which there are substances that absorb a fraction of the light and reflect their Complementary part, coated with aldehyde or ketone resins. The latter are deposited on the surface of the pigment by means of a process that provides for the fusion of resin, the consequent wetting and coating in the molten state, the consequent cooling and the subsequent atomization step, by means of mechanical systems operating in conditions of temperature less than 10 degree C, by means of cryogenic processes. The product resulting from this invention will be used as a semi-finished product for the coloring and pigmentation of powder and plastic paints, as a monochromatic coloring material, and / or will also be used, after dissolving in a solvent, such as a pigmented paste in the liquid paint industry. |
