AASHTO M247 II Reflective Glass Beads

I. Role of Reflective Glass Beads

Reflective glass beads are essential retroreflective components in thermoplastic road marking paint, providing:

• Nighttime visibility: Retroreflection of vehicle lights enhances low-light visibility for road markings.
• Longevity: Embedded beads reduce surface wear, extending marking durability.
• Weather resilience: Maintain performance in rain, fog, and extreme temperatures.

II. Key Advantages

• High refractive index (1.5): Superior light reflection vs. conventional materials.
• AASHTO M247 II compliance: Particle size 200-1000μm with 80% sphericity for precise light control.
• Environmental safety: RoHS/REACH compliant, zero heavy metals.
• Seamless integration: Direct compatibility with thermoplastic road marking paint.
• Cost efficiency: 15-30% paint weight ratio lowers lifecycle costs.

III. Technical Specifications

IV. Application Guidelines

• Storage: Keep sealed in dry, non-corrosive environments.
• Mixing: 15-30% weight ratio with thermoplastic road marking paint.
• Temperature: Apply at 180-220°C to preserve bead integrity.
• Safety: Use PPE and proper waste disposal protocols.

V. Summary

AASHTO M247 II reflective glass beads deliver unmatched nighttime visibility and durability for thermoplastic road marking paint. With 1.5 refractive index and optimized particle gradation, they meet rigorous performance standards while reducing maintenance costs.
