More Information
Summary:The present invention relates to a method of obtaining an additive for coatings that contains nanoparticles of one or more compounds, preferably metallic, selected in relation to the property that is desired to be transferred to the coating, which comprises a first pretreatment phase in which the water content of the active agent is reduced, replacing it with a vehicle compatible with the coating, and a second phase in which it is mixed with a resin compatible with the coating, a dispersant and a solvent, which are also compatible with it. The additive produced by this method contains nanoparticles of one or more compounds, preferably metallic, which become dispersed homogeneously in the coating once incorporated therein.
