| 20100298472 | COATING OF ORGANIC AND INORGANIC PIGMENTS WITH ACRYLIC RESINS - Coating of organic and inorganic pigments with acrylic resins, comprising a chemical compound consisting of particles of solid organic and inorganic substances, both defined as pigments, in that they are substances which absorb a fraction of the light and reflect the complementary part thereof, coated with acrylic and, optionally, aldehyde and/or ketone resins. The latter are deposited on the surface of the pigment by means of a process which envisages melting of the resin, consequent wetting and coating of the entire surface of the pigment with the resin in the melted state, the consequent cooling and subsequent step of grinding by means of mechanical systems operating in temperature conditions lower than 20° C., by means of cryogenic processes or granulate by means of a wet method with a water jet cutting action and separation of the granulates by the water on a vibrating screen and then dried on a spiral elevator. The product resulting from this invention will be used as a semifinished product for the colouring and pigmentation of powder paints and plastics as a monochromatic colouring material and or will also be used, after dissolving in a solvent, or in water with basic pH, as a pigmented paste or directly in solvent or water based resins in the liquid paints industry. | 11-25-2010 |
| 20100081745 | METHOD FOR PREPARING PAINTS AND INKS - The present invention relates to a method for preparing paints and/or inks in which a particle composition consisting of pigment dyestuff, an aldehyde, ketone and/or acrylic resin and optionally excipients and/or adjuvants are mixed into at least one organic solvent, water or a mixture thereof. | 04-01-2010 |
| 20100004387 | PROCESS FOR PREPARING GRANULES OF PIGMENTS BY MEANS OF DOUBLE EXTRUSION - A process for the production of a particle composition containing, at least one resin and at least one pigment is described, said process comprising the following steps : •extrusion of a mixture containing said at least one resin and said at least one pigment without induced heating; •subsequent extrusion, with induced heating, of the mixture obtained from the preceding extrusion; •granulation of the mixture thus obtained. With the abovementioned process it is possible to obtain a composition having granules with an average diameter less than 2 microns and a greater homogeneity than the known processes. | 01-07-2010 |
