Introduction
Using glass beads as reflective material in road marking (paint) can improve the performance of reverse reflection of road marking paint and enhance the safety of driving at night, which has been determined by the traffic departments of various countries. When the car is driving at night, the car lights shine on the road signs with glass beads, which can make the light of the car lights reflect back in parallel, so that the driver can see the direction of travel, improve the safety of driving at night. Now, reflective glass beads have become an irreplaceable reflective material in road safety products.
