What is Thermoplastic Paint
Thermoplastic road marking paint, also called hot melt marking paint, is a specialized type of powder paint made from thermoplastic materials. This paint consists of a mixture of resin, pigments, glass beads, fillers, and various additives.
Thermoplastic powder paint requires specialized equipment like a preheater machine (hot melt machine) which heats it to 200°C (392°F) to melt the powder. When heated, this material becomes liquid and can be applied to road surfaces. Once it cools and solidifies, it forms a durable and long-lasting marking on the road.
The unique characteristic of thermoplastics is their ability to soften when heated and solidify when cooled. This property allows for easy application and ensures a long-lasting and robust finish on road surfaces.

Safety Benefits
One of the most important benefits of using thermoplastic road markings is the improvement to road safety. Thermoplastic markings can be made to be highly reflective, making them much easier to see at night or in bad weather conditions where visibility is poor.
Thermoplastic markings can be laid thicker, and built-up layers of the paint are used to create rumble strips which provide drivers with physical feedback in the form of noticeable vibration and an audible rumbling noise. This helps raise awareness of upcoming danger spots and warns drivers to watch their speed, resulting in less frequent collisions and accidents.
