What are the raw materials for road hot-melt coatings?

The raw materials for road hot-melt coatings mainly include synthetic resins, coloring pigments, bulk pigments, reflective glass beads, and additives. ‌
Synthetic resin: It accounts for about 15% to 20% in hot melt coatings, mainly using petroleum resin, which is a solid resin that plays an important role in the fluidity and adhesion of coatings. ‌
Coloring pigments: used to adjust the color of coatings, including titanium dioxide (for white coatings) and medium chrome yellow (for yellow coatings), accounting for approximately 5% to 10% of the coating. ‌
Constitutional pigments: accounting for approximately 50% to 60% of coatings, the main components are calcium carbonate, quartz sand, wollastonite powder, calcite powder, talc powder, etc. These components are the main components of hot-melt coatings. ‌
Reflective glass beads: accounting for 18% to 25% of the coating, used to improve the reflective performance of the coating, and form a reverse reflection effect by shining night lights on road markings. ‌
Additives: accounting for 3% to 5% of the coating, including vegetable oil, mineral oil, whitening agent, silicone oil, antioxidant, etc., mainly used to adjust the flowability, workability, flexibility of the coating film, drying speed and other properties of the coating. ‌
The reasonable ratio and use of these raw materials make hot melt coatings have good workability, durability, and reflective performance, suitable for traffic facilities such as road markings, to improve road safety and visibility
