BS6088 A、BS6088 B Glass Bead

Factors affecting retroreflectivity:

■ Glass bead coverage

■ Grading (size distribution of glass beads available for the application)

■ Color/transparency/defects

■ Roundness

■ Marking coating quality

■ Settlement depth (embedding)

■ Refractive index

■ Other application variables (road surface, weather, volatile organic compounds in the coating, etc.)

l  Lightweight Properties

 Engineered with an optimized density to ensure excellent yield per square meter without adding unnecessary weight to the coating system.

l  Superior Durability & Strength

 Boasts high Mohs hardness and exceptional abrasive wear resistance, guaranteeing that the markings withstand heavy traffic loads and prolonged friction.

 l  Advanced Surface Treatment

 Specially treated to be lipophilic (oil-loving) and hydrophobic (water-repelling). This ensures perfect wetting and bonding with acrylic/two-component resins while repelling moisture for long-lasting adhesion.

 l  Excellent Thermal & Chemical Stability

 Features low thermal conductivity and outstanding resistance to acids, alkalis, and automotive chemicals. It prevents the marking lines from degrading under extreme weather or harsh road conditions.

Visibility in Wet/Night Conditions

Conventional glass beads work well in dry conditions but lose effectiveness when wet. A water layer on the road causes light to scatter (specular reflection), reducing visibility for drivers. The solution is to use larger glass beads that protrude above the water film. This ensures light is consistently reflected back to the driver, enhancing retroreflection and safety in rainy conditions or at night.
