China Drop on Glass Beads for Road Safety

Drop-on Glass Beads
During the process of road work, drop glass bead onto the road line painted with thermoplastic paint which is heated to certain temperature while the paint is still wet, thus to increase the reflectivity of road marking. According to the specification of Communication Industry Standard of the People's Republic of China No. JT/T446-2001.
There are two Grades: Grade A & Grade B and high refractive index Glass Beads available:
Grade A, used to be mixed with the paint prior to stripping the road. As the paint layers wear, the beads are exposed giving the enhanced visibility of road markings.
Grade B, used to be dropped on the freshly stripped paint surface on the road to give immediate enhanced visibility to night drivers.
