Glass beads are used as high-performance organic materials where the external glass surface reduces dust adsorption from the air. Due to specific coupling agents in the beads, cohesion with coatings is enhanced, preventing tiny glass beads from penetrating the coating. Their flotation function allows them to rise to the coating surface, increasing utilization by over 30%. Reflective glass beads have become indispensable in road safety products.
We provide glass beads with refractive indices of 1.53, 1.72, and 1.93, available in various national standards or custom size distributions.
