AASH M247 High Reflective High Roundness Road Marking Glass Beads Powder Coating
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 coating surface, 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.
We provide glass beads with different refractive indices of 1.53, 1.72, 1.93 and more. We can also supply glass beads according to various national standards or custom size distributions provided by customers.
