The invention concerns an accelerator for an aqueous paint drying time comprising mineral particles, a polymer binder in aqueous dispersion and a polymerising agent in emulsion, as well as the corresponding paint. The accelerator has a polymeric structure, is water-soluble and comprises cationic loads. The invention also concerns a method for applying on a support said aqueous paint, which consists in spraying the paint on the support, distributing reflecting beads into the paint and incorporating into the paint, preferably after the beads have been distributed, the drying time accelerator. The invention is applicable to road marking.
La présente invention concerne un accélérateur de temps de séchage d'un peinture aqueuse comprenant liant polymère en dispersion aqueuse et un agent de polymérisation en émulsion, ainsi que la peinture correspondante. L'accélérateur a une structure polymérique, est hydrosoluble et comporte des charges cationiques. L'invention concerne également un procédé d'application sur un support d'une peinture aqueuse conforme à l'invention, selon lequel on pulvérise la peinture sur le support, on distribue des billes réfléchissantes dans la peinture et on incorpore dans la peinture, préférentiellement après la distribution des billes, l'accélérateur de temps de séchage. Application au marquage routier.
