Roadex Glass Beads

Description

Roadex Glass Beads are manufactured as per British standard BS-6088-A and AASHTO-247-M to meet the retro reflection of all types of road marking paint e.g. Thermoplastic Hot Melt, Chlorinated Rubber (CR), Water-Based and Cold Plastic two-component to provide excellent night retro-reflectivity.

The Glass Beads are coated with silicon which can improve the coupling between glass beads and road marking materials, prevents sinking of glass beads to the bottom of material and give maximum reflection.
