What's for?

Glass Beads for Road Marking can improve visibility of the traffic markings and road signs and supply safer night driving conditions. 

 

The grade BS6088:
There are two Grades: Class A & Class B and high refractive index Glass Beads available. Class A is used to making manufacture of reflective thermoplastic road marking paint. Class B is used to be dropped on the freshly stripped paint surface on the road to give immediate enhanced visibility to night drivers.
