Traffic marking paint is applied to the road to indicate the traffic. There are generally four categories: solvent-based, Thermoplastic , two-component, water-based.

Solvent-based traffic paints normally using chlorinated rubber, epoxy resin and acrylic resin as the filming Substances, that require large amounts of organic solvents. The release of organic solvents can cause environmental pollution, so its market share is gradually decreasing.

Water-based traffic paint uses water as a solvent, has good environmental performance, and has excellent adhesion to cement roads. It is not necessary to remove old lines for re-construction, but the production cost is higher. To get a wide range of application, some performances need the further improvements.

Two-component traffic paint mainly select epoxy, polyurethane and acrylic as the resin. The two components are polymerized after mixing and solidification to form a network structure with high adhesion, hardness and mechanical strength. Confined by the construction process and equipments, it is still under the development.

Thermoplastic traffic paint is made of petroleum resin or natural resin. The coating has the characteristics of short drying time, good adhesion to the road surface, no pollution to the environment, and short production period and low investment.

The compositions are thermoplastic resin, pigment fillers and auxiliary agents. The working temperature is heated to 180-220 ° C by special equipment to be applied by scraping or extrusion or spraying. The service life is generally 2 to 3 years.

Fischer-Tropsch wax can improve the dispersibility of pigments and fillers in thermoplastic resins, prevent sedimentation, adjust viscosity, lower softening point and improve paint fluidity, reduce film surface tension, and improve wear resistance and stain resistance.
