Reflectivity: Glass beads reflect light from vehicle headlights, making road markings more visible to drivers at night. This is crucial for road safety.
Durability: Glass beads help increase the lifespan of road markings. They provide a protective layer that prevents the paint from wearing out too quickly due to traffic and weather conditions.
Anti-skid Properties: The rough surface of glass beads can enhance the anti-skid properties of road markings, improving traction for vehicles, particularly in wet or icy conditions.
Uniformity: Glass beads ensure a uniform distribution of reflective material across the road marking, maintaining consistent visibility.
