Reflective Glass Beads For Road Marking | AASHTO M247 EN1423 Certified Glass Spheres
Glass beads are used as high-performance, organic materials that reduce surface adsorption of dust in the air. Due to the specific coupling agent contained in the beads, they improve cohesive force with coatings and prevent tiny glass beads from sinking into the coating. Their flotation function allows them to float on the surface coating, providing a large surface area that increases utilization rate by more than 30%. Reflective glass beads have become an irreplaceable reflective material in road safety products.
