The two-component road marking is a new type and superior road marking and popular in recent years. It is different from thermoplastic and cold plastic road marking, which forms coating relying on chemical reaction instead of physical drying such as temperature falling or solvent (water-based) volatilizing. The two component road marking machinery can be divided into swing structure type, screeding flat-line type and high-pressure airless spraying type according to different paints and different construction shapes.

Meanwhile, these three types can be divided into marking vehicle, driving type and self-propelled type according to different degree of automation, functional configuration, construction quality and efficiency. As for the two-component marking vehicle, its truck platform and electronic control system are basically the same with the airless road marking truck except its functional module.
