Due to the recent increase in nightwalkers and pedestrian traffic accidents, interest in products using retro-reflection has increased, and many studies on retro-reflection are being conducted. However, it is not easy to disperse retro-reflective glass beads in viscous coating resin and to acheive high durability. In this work, we functionalized glass beads surface which can be covalently conjugated to coating resin to enhence dispersibility and durability in coating resin. The dispersibility, chemical composition, mechanical and retro-reflection properties of functionalized glass beads and coating resin were investigated. The functinalized glass beads were covalently conjugated to coating resin and showed well dispersibility and high durability without diminishment of retro-reflection efficiency.
