The thermoplastic path marking paint , also called hot melted paint , is a kind of powder paint. When used as a road surface marker, a hot kettle is used to heat it up to 200 ° C (392 ° F), after which it is sprayed onto the road surface. The layer then becomes the line after cooling. This paint is thick, wear resistant, bright and reflective. In recent years, practical applications have proven that the tagging line has no specific surface roughness and can easily cause wheel slippage, resulting in traffic accidents in snow and rainy weather. Therefore, some countries have limited the use of this paint. To improve the anti-slip line performance, thermoplastic paints have added reflective glass beads. Thermoplastics can be used very effectively for large anti-skid areas in roads and pedestrian walkways by adding glass beads. It can be produced in any color and is great for car parks, factory walkways and many other areas. It dries quickly and can be moved after just a few minutes.

Components
Thermoplastic marking paint is mainly composed by synthetic resins, glass beads, pigments, packaging materials, additives, etc.
- Synthetic resins have thermoplastic properties, making hot melt coating dry and strong adhesive to the road surface.
- Additives in paints can enhance the plastic layer, and make it resistant to degradation, pollution and color fading.
- Pigments: street line colors are generally yellow and white. White pigments are mainly titanium dioxide, zinc oxide, and lithopone, while the yellow pigment is primarily a heat-resistant yellow tin.
- Packing material, as stuffing added to the paint, ensures mechanical strength, wear resistance, and paint coat color. The particle size will affect liquidity and precipitation, as well as surface treatment.
- Glass beads are added to improve line identification at night, to improve the brightness and durability of the marking. The glass beads are colorless and the ball is transparent, it has the function of light refraction, focus and directional reflection. Glass beads mixed in layers or removed throughout the coating surface can reflect back the car's light to the driver's eyes, greatly enhancing the visibility of the marking.

The appropriate machine
Road marking machine is a special machine used to mark different traffic lanes on the road surface, and some can comment on the old channel directly. Can be screed or painted road paint spray onto the road surface to form a hard coating line. Hot water boilers are used for continuous heating, melting, and stirring thermoplastic marking paints, preparing liquid paint for thermoplastic machines, especially for long distance jobs, road lines. The quality of the melted paint greatly affects the quality of the line.
