Rain-Night Retroreflective Glass Beads: The Key to All-Weather Road Safety

Rain-night glass beads are manufactured using advanced high-refractive-index glass and surface-coating technology. These enhancements allow them to maintain retroreflection even when covered by water.

Key features include:

• High refractive index (≥1.5 or 1.6 depending on the grade)

• Special surface treatment for water penetration and stable optical performance

• Optimized roundness for improved light return

• Multi-layer coating to resist moisture and maintain reflectivity

When applied as drop-on beads or intermix beads in road marking paint, they create a reflective system that performs reliably during rainy nights.

Applications in Road Marking Systems

Rain-night reflective glass beads are widely used in:

• Thermoplastic road marking paint

• Water-based road marking paint

• Cold plastic coatings

• All-weather lane markings

• Highway, airport, and tunnel markings

Many countries now require EN 1436 Wet Visibility (RLwet) compliance for critical roads. Rain-night beads are essential to achieving these standards.

Benefits for Road Authorities & Contractors

Using rain-night reflective glass beads brings several measurable advantages:

• Improved wet-night safety for drivers

• Lower accident rates in poor weather

• Compliance with Type II / EN1436 standards

• Longer service life of road markings

• Better performance under heavy traffic and harsh climates

With increasing requirements for all-weather road performance, these beads have become a key upgrade for national and municipal road projects.

Conclusion

Rain-night retroreflective glass beads play a vital role in modern traffic safety. Their enhanced optical performance ensures road markings remain visible in the most challenging conditions—rain, fog, and nighttime driving.
For contractors and road authorities looking to improve road safety and meet international standards, these all-weather reflective beads are an indispensable solution.
