Enhancing the refractive index of road marking 2019-04-12 Road glass beads are mainly used in normal temperature and hot-melt road marking paints. There are two types: pre-mixed and surface-spread. The pre-mixed glass beads can be mixed in the paint during the production of hot-melt road coatings, which can ensure long-term reflection of road markings during the life of the road. The other can be sprinkled on the surface of the road marking to have an instant reflective effect during road marking construction. Surface-treated coated glass beads are used in road marking construction, which can greatly improve the adhesion of glass beads to hot melt markings, enhance the refractive index of road markings, and have self-cleaning, anti-fouling, Use for moisture proof. Road glass beads are used to improve the reverse performance of road coatings and improve the safety of drivers driving at night.
