Thermoplastic road marking paint is the most favored material for road marking due to it being hard-wearing and reflective, making it ideal for high-traffic roads and highways. It is applied to the road surface by spray after heating to 180 degrees Celsius, which is why it’s sometimes called hot melt marking paint or hot tape. For extra surface friction and reflectivity, glass beads and fillers are often added to the paint to improve safety. Pre-formed thermoplastic tape can also be used for line marking.
