Glass beads 6088A and 6088B are transparent, hydrophobic beads used in road marking paints to improve the visibility and durability of road markings. From Puyang Tennants Chemical CO. LTD. in China, these beads are available in different sizes, with a diameter range from >1180 μm to <425 μm.

The glass beads meet specifications, including a hardness of 6-7 on the Moh's scale and a refractive index exceeding 1.5 for long-lasting reflectivity. The beads have roundness, with 81% of the sample weight being round beads, these give smooth application and consistent performance.

Additionally, the beads' specific gravity of 2.46 g/cm3 and silica content greater than 65% contribute to their high durability and resistance to wear and tear.
