Product Description
Refractive Index Nd≥1.5% Glass Beads for Road Safety Pavement Striping
Glass beads are used as high-performance, organic materials applied externally to glass beads, reducing surface adsorption of dust in the air. Due to the specific coupling agent contained in the glass beads, the cohesive force between beads and coating is improved, preventing tiny glass beads from sinking into the coating. With their flotation function, they 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.
