Glass Beads Nd≥1.5% Round Rate ≥85% For Sidewalk & Tactile Paving Markings
Glass beads are high-performance, organic materials used externally to reduce surface adsorption of dust in the air. Due to specific coupling agents, these beads improve cohesive force with coatings, preventing tiny glass beads from sinking. Their flotation function allows them to remain on the coating surface, increasing utilization by over 30%. Reflective glass beads have become essential materials in road safety products.
We provide glass beads with refractive indices of 1.53, 1.72, 1.93, and more. We can supply beads according to various national standards or custom size distributions as specified by customers.
