Ltd, 2Kyungpook National University, 3Kyungpook National University Pages/Total page pp.98 ~ 106 / 9 Language Korean Abstract The recent surge in night walkers and pedestrian traffic accidents has led to an increased interest in retro-reflection-based products, leading to several studies on retro-reflection. Nonetheless, achieving high durability and dispersibility of retro-reflective glass beads in viscous polyurethane coating resin remains challenging. To address this issue, this study conduct to functionalize the surface of glass beads for covalent conjugation to coating resin to enhance their dispersibility and durability in the coating resin. The study evaluated the dispersibility, chemical composition, and retro- reflection properties of the functionalized glass beads and coating resin. The results showed that the functionalized glass beads conjugated to the polyurethane coating resin and exhibited excellent dispersibility, high durability, and maintained retro-reflection efficiency.
