Wholesale High Quality Glass Beads for Road Marking Traffic Paints
Glass beads are high-performance, organic materials used in road marking applications. The specialized coating on these beads reduces surface adsorption of dust from the air, while the specific coupling agent enhances cohesion with paint coatings. This prevents tiny glass beads from sinking into the coating due to their flotation function, allowing them to remain on the surface where they provide maximum reflectivity. With their large surface area, these reflective glass beads increase utilization efficiency by more than 30%, making them an irreplaceable material in road safety products.
We provide glass beads with different refractive indices including 1.53, 1.72, and 1.93. We can also supply glass beads meeting various national standards or customized to specific size distributions as required by customers.
