Reflective glass beads for road markings are classified based on their application method: Drop-on Glass Beads These beads are sprinkled onto the surface of the road marking paint while it is still wet. Due to gravity, some of the beads partially embed into the coating, creating an immediate reflective effect. Intermix Glass Beads These beads are pre-mixed into the marking paint before application. As a result, they are more securely bonded to the paint and less likely to wear off, ensuring long-term reflectivity throughout the lifespan of the road marking.

Our high-index glass beads are engineered for road safety and industrial applications. When embedded in traffic paint or thermoplastic markings, they reflect headlights at night, improving visibility for drivers. They're also used in airport runways, high-visibility clothing, and industrial coatings where retroreflective properties are critical.

The size you choose will depend on your particular application: 0.7-1.0mm beads‌ work best for water-based paints, 1.5-2.0mm beads‌ are ideal for thermoplastic applications, 2.5-3.0mm beads‌ perform optimally in heavy-traffic areas, Our technical team can provide free gradation charts and ASTM E11 compliance documentation upon request.

Yes, our beads undergo a specialized surface treatment process that increases alkali resistance by 40% compared to standard beads. Independent testing shows 92% reflectivity retention after 18 months in harsh climates.

All batches are certified to EN1423/1424 (Europe), AASHTO M247 (USA), and JIS R3301 (Japan) standards. Our ISO 9001:2015 certified facility conducts three quality checks: raw material screening, mid-production refraction testing, and final batch moisture analysis (<0.3% humidity threshold).
