Definitions

  • the invention relates to the field of marking hard surface substrates, in particular to the field of traffic paints.
  • the invention thus provides an aqueous composition useful for marking hard surface substrates.
  • the composition according to the invention comprises a binder and a pigment that is dispersed with a particular (meth)acrylic polymer.
  • the invention also provides a method for preparing such a composition as well as a method for marking a hard surface substrate with such a composition.
  • compositions comprising a binder and a pigment dispersed with a dispersing agent for marking hard surface substrates are known.

  • the binder that is used in such compositions is a latex binder.
  • compositions are their ability to dry rapidly once applied on a hard substrate, in particular on a substrate that is aimed for traffic of vehicles or for traffic of persons. Fast drying is of particular importance in high humidity conditions.
  • Good drying time normally corresponds to improved performance in certain tests, notably in test where no-pick up time of a film coating is measured.
  • Wear resistance of a film coating is normally the ability of this film coating applied on a surface to resist to detachment or separation from the substrate. Such a detachment or separation can occur for various reasons but is normally depending from the use conditions of the film coating that include the level of traffic, the weather conditions as well as the intrinsic specifications of the film coating.
  • compositions for traffic paints are ammonium salts of polyacrylic acid or ammonium salts of polymethacrylic acid, wherein volatility of ammonia is considered helping accelerating drying time of these compositions.

  • Controlling the rheology, in particular the viscosity, of such compositions also allows for an easier use, notably in situations where these compositions must be pumped or must be sprayed.
  • Fineness of ground pigments used in paints is also important since coarse pigment particles generally reduce the properties of a paint, notably color uniformity and opacity. Grinding efficiency of the pigment, including grinding time, is also important in the course of preparing the pigments to be incorporated in the compositions for marking hard surface substrate.
  • Satisfying regulations or certain standards is also important for compositions for marking hard surface substrates, notably for traffic paints, in particular when shorter drying time is required.
