Description
ST-GB Glass Beads for road marking machine
The superior properties are as following:
Use the material with the similar refraction ratio to the glass
beads’ in order to protect the glass beads’ retro-reflection
property.
The normal glass beads will be wrapped with water film in rainy
days and foggy days, so the reflective effect will be affected, but
the coated glass beads may have obvious improvement on this
problem.????
The fluidity debase significantly if the glass beads are damped,
which could cause glass beads accumulation in the dispenser. The
coated glass beads can avoid accumulations in the dispenser, which
may affect the construction efficiency.???
Particular coupling agent in the coated glass beads can improve the
adhesion between the glass beads and the paint.
Small glass beads will not deposit in the paint.
After the filming coating, the strong polar group on the surface of
the glass beads change into nonpolar group, which can reduce the
dust in the air absorbed on the surface of the glass beads.
