Wet Road Rainy Reflective Glass Beads

tailor made for every kind of performance requirement

high-performance glass beads

    Our highly reflective TORY® make marking systems more visible at night, in particularunder wet conditions. This effect is achieved, firstly, by their crystal clear surfaces and, secondly, by thelarge diameter: Consequently, the bead protrudes out through the film of rain and is able to reflect thebeam from the headlight. Suitable for thin-layered marking systems with increased requirements forvisibility in the wet.

    D-HR glass beads are applied under gravity or pressure as a surface application to a wet film of pavement-marking material to provide retroreflectivity. When these beads are applied on a smooth substrate, a nominal rate of 500 g/m2 may be appropriate. A coarse surface substrate usually requires a higher rate of application of beads to achieve a similar level of retroreflectivity. 

     These beads have no moisture-proof coating and are, therefore, also suitable for intermixing into thermoplastic pavement-marking material to provide retroreflectivity in both dry and wet conditions throughout the life of the marking. These beads should be intermixed at a rate of not less than 20% by mass.

RETROREFLECTIVITY VERIFICATION OF TYPE D-HR BEADS 

(Informative) 

D-HR玻璃珠

    The minimum level of retroreflectivity for Type D-HR glass beads is 600 mcd/㎡/lux。

    High Performance beads are made from 100% virgin glass. Due to their size, their high roundness (options up to 90%), and superior glass composition, expect the highest level of retroreflection, especially on wet-night conditions. TORY D-HR glass beads are one of the most cost-effective and sustainable ways to increase road safety.

Recommended applications: 

• High-quality drop-on, especially with high requirements for wet-night reflection 

• Can be applied with standard road  marking equipment
