อาชตู Type I II III Traffic Safety Micro Glass Bead สำหรับการสลักเครื่องหมายบนถนน

During production of paints, qualified glass beads will be mixed into them as certain proportion required by standards. Certain proportion Glass beads will be dropped on the surface of paint, whihc is mexed with glass beads, during its application while the paint is still wet.

Under the feeect of gravity of glass beads itself, the glass beads will inlaid into paint by part of their surface. When the car light attaches Such kind of road marking lines, the light will be reflected back to the eyes of drivers to increase the driving safety at night.

The glass beads can be divided as intermix beads and drop on beads according to the usage of them, and also can be divided As moisture-proof beads, adhesive coating beads and dual-coated beads.

Traffic bead for road safety, we can produce different standards glass beads, such as BS6088, EN1423/1424, KS L2524, AASHTO, AS etc.
