It all starts with the paint: we say that we “formulate” a marking paint. It is a mixture of pigments, binders, solvents also called “vehicles” and additives. The properties of a paint depend on the formulation, i.e. the choice of these constituents and the way they are mixed.  The binder: This is what ensures that the paint adheres to the substrate. These are polymers or “resins” chosen according to the characteristics expected of the paint Pigments : These are powders that are insoluble in water or solvents and provide the colour. They are chosen to be fluorescent to make FLUO TP and FLUO TP Hydro. The vehicle: This is a liquid, water or solvent that helps transfer the paint to the substrate. The additives: provide or improve certain characteristics of the paint (thickener) during its manufacture or use (anti-foam, anti-corrosion). Then, a liquid gas is introduced (liquefied propellant gas, a mixture of liquid and gas under pressure (DME or Butane Propane) which is miscible with the paint. The metal casing must be well sealed and equipped with a valve, a diffuser to extract the paint and a protective cover.
