Thermoplastic Road Marking Paint

Road marking not only guides vehicles and pedestrians to pass in an orderly manner, but also greatly improves road safety. Among many road marking paints, thermoplastic road marking paint has become the first choice for urban roads and heavy traffic areas due to its unique performance and wide range of applications.

Unique features of thermoplastic road marking paint

The biggest difference between thermoplastic road marking paints and traditional road marking paints is that they contain no solvent volatile components. This feature makes hot melt marking coatings more environmentally friendly and reduces harmful emissions during the construction process. During construction, the electrostatic powder is heated and melted, and then evenly coated on the ground with a road marking machine to form a bright and durable marking line after it physically solidifies. This process avoids the traditional way of relying on solution evaporation to realize the drying of the coating film, and instead relies on the solidification and curing mechanism of physics, thus realizing a fast and efficient construction effect.

Advantages and characteristics of thermoplastic road marking paint construction

• Ultra-fast drying: thermoplastic road marking paint can be dry and open to traffic within 1-3 minutes after painting, which greatly shortens the construction period, and can even be constructed without interrupting the traffic, which is especially important for urban roads with heavy traffic.
• Excellent abrasion resistance: thanks to its thick coating (typically 1.52mm thick, with an application volume of about 45kg/m²), thermoplastic road marking paint provides long-lasting abrasion resistance and a service life of up to 2 years for road markings, significantly reducing maintenance costs.
• Clear reflective effect: By adding glass reflective material into the hot melt coating and spreading glass marbles on the surface of the coating during the construction, it can effectively improve the reflective effect at night, enhance the visibility of the road marking, reduce the occurrence of traffic accidents and meet the requirements of modern traffic safety.
• Good visual effect: the coating of hot melt surface layer has clear lines, sharp edges and high brightness, which enhances the sense of hierarchy of road marking and improves the aesthetics of the road.

Thermoplastic road marking paint economy and applicability analysis

Although the price of thermoplastic road marking paint is relatively low, due to its large coating thickness, the cost per unit area is high, usually several times higher than that of the marking paint used at room temperature, which makes the application in the region of relatively lagging behind in economic development limited. In addition, hot melt coating on the construction of pavement conditions have higher requirements, the most suitable for the newly paved pavement, for there has been a long period of aging or cracking of asphalt pavement is not suitable for use.

Thermoplastic road marking paint future prospects

With the progress of science and technology and environmental awareness, thermoplastic road marking paint research is toward improving the corrosion resistance of the film and water resistance direction, while trying to maintain its original excellent characteristics, and reduce the construction process of organic solvent evaporation, and enhance the adhesion of the coating and pavement. These efforts are aimed at broadening the application range of thermoplastic road marking paint, making it more adaptable to the complex and changing road environment, providing a more solid guarantee for road safety.
