It is the complementary product of the road marking paint applied with glass beads. In order to ensure night visibility, both the glass beads added to the paint during the production process and the glass beads sprinkled on the paint before it dries during the application have a direct effect. Depending on the applied paint, the coating on the glass bead may differ. The roundness and gloss ratio of the glass bead increase its light re-reflectivity and traffic safety.
