Glass Beads for Road Marking

Reflective Glass Beads can perfectlyimprove visibility of the traffic markings and road signs and supply safer night drving conditions.

the glass beads can be pre-mixed to making of reflective thermoplastic paint or used to be dropped on the freshly stripped paint surface on the road to give immediate enhanced visibility to night drivers.
