Abstract
This invention relates to a drying time accelerator for a water-based paint comprising mineral particles, a polymer binder with water-based dispersion and an emulsion polymerization agent, as well as the corresponding paint. The accelerator has a polymeric structure, is water-soluble, comprises cationic charges, and is selected from metallic polychlorides, metallic polyoxychlorides, or synthesis polyacrylamide polymer. The invention also relates to a method for applying a water-based paint according to the invention onto a support, according to which the paint is sprayed onto the support, light-reflecting balls are distributed in the paint, and a drying time accelerator is incorporated into the paint, preferably after distribution of the balls. The application of the invention is to road markings.
