Definitions

  • the object of the present invention is a pigment paste applicable in coatings, comprising, pigments, dispersants, film-forming resin and solvents; as well as a method for its manufacture.
  • This invention has characteristics aimed at achieving a pigment paste with a degree of fineness or particle size less than one mill.
  • the pigments are made up of insoluble, organic and inorganic products, used to cover the applied surface by changing its color, appearance and finish. It should be mentioned that the pigments have a very variable particle size, and cannot be used without prior dispersion, since a heterogeneous, rough layer with a final appearance that would not meet the minimum quality requirements would be obtained.
  • An objective of the manufacturers of these pigment pastes is to improve the color yield and the quality of the finish, the applicant of the present invention being unaware of the existence in the market of pigment pastes that provide a finish and a quality greater than that achieved with the techniques of dispersion used previously and in which pigment pastes reach a fineness between 5 and 25 microns.
  • the pigment paste object of this invention being applicable in coatings, and comprising in its composition insoluble pigments, dispersing agents, film-forming resin and solvents; It has characteristics aimed at solving the problems mentioned above and specifically to obtain a degree of dispersion of the pigments that provides surprising effects in terms of color performance and the quality of the finishes of the coatings.
  • the pigment paste of the invention comprising in its composition the elements mentioned above that is to say: insoluble pigments, dispersing agents, film-forming resin and solvents has the particularity of being constituted by a nanodispersion of the insoluble pigments in the indicated components, presenting the pigment paste a degree of fineness or particle size less than 1 miera.
  • This degree of dispersion and size of insoluble pigments, less than 1 meter, provides surprising improvements compared to traditional products, the following being noteworthy: - Improvement of color performance.
  • the stability of the pigment paste with this degree of dispersion of the pigments is achieved through the use of dispersing agents, preferably polymeric and film-forming resins, preferably alkyd or aldehyde, compatible with the formulations of the coatings to be manufactured.
  • dispersing agents preferably polymeric and film-forming resins, preferably alkyd or aldehyde, compatible with the formulations of the coatings to be manufactured.
  • the weight percentages of the different components of the pigment paste are included in the following values:
  • pigments from 1,00 to 40,00%; dispersing agent from 0.00 to 30.00%; film-forming resin from 1,00 to 40,00%; and solvents and / or water in the remaining percentage until reaching 100.00%.
  • Also included in the present invention is a method for manufacturing the pigment paste described above, said method comprising the following steps: - the nanodispersion of the components in a dispersion machine using Zirconium-Ytrium microspheres of a section between 0.1 and 0.3 millimeters, until reaching a pigment paste with a fineness or particle size of less than 1 mire ;
  • the pigment paste comprises the percentage by weight of the components mentioned below: 30% insoluble pigments, 20% of a dispersing agent, namely polymeric, 30% alkyd film-forming resin and 20% solvent, specifically in this case butyl glycol acetate; the pigment paste presenting a degree of fineness or particle size of less than 1 miera.

Abstract
