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. 

     我们的高反光 TORY 使标记系统在夜间更加醒目，尤其是在潮湿条件下。 这种效果首先是通过其晶莹剔透的表面实现的，其次是通过大直径实现的：因此，珠子从雨膜中伸出并能够反射前灯的光束。 适用于对潮湿可见度要求更高的薄层标记系统。

     D-HR 玻璃珠在重力或压力下作为表面应用施加到路面标记材料的湿膜上以提供逆向反射性。 当这些珠子应用于光滑的基材时，500 g/m2 的标称比率可能是合适的。 粗糙表面的基材通常需要更高的珠子应用率才能达到类似水平的逆向反射率。

      这些珠子没有防潮涂层，因此也适合混合到热塑性路面标记材料中，以在标记的整个生命周期内在干燥和潮湿条件下提供逆向反射性。 这些珠粒应以不小于20质量％的比率混合。

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

注：玻璃珠的粒径，级配一样，不代表其逆反射性能一样。
