Traffic Road Safety Reflective Glass Beads for Road Marking Paints
Reflective glass beads are high-performance organic materials used in road marking paints. The surface treatment reduces dust adsorption and improves cohesion with coatings, preventing tiny beads from sinking due to flotation function. This increases surface area and utilization rate by over 30%, making them essential for road safety applications.
We provide glass beads with refractive indices of 1.53, 1.72, 1.93, and more. Available in various national standards or custom size distributions as per customer requirements.
