Retroreflective Glass Beads
Retro-Reflective Glass Beads are solid spherical glass beads for use with long life (thermoplastic & cold applied plastic ) road marking materials and road marking paints (both water and solvent based), meeting specifications AS/NZS 2009 / NZTA T17. When vehicle headlights shine onto glass beads, the light is reflected back to the light source (retro-reflective) resulting in the driver seeing a glowing bright line. Glass beads also help reduce wear of marking materials.
