Description

Glass Beads are tiny glass particles that are added to road marking paint to make marking lines possess reflectivity. There are three types of glass beads distinguishing themselves from each other by size of particles: type one of the biggest size can be directly mixed in thermoplastic paint during production; type two of the medium size is used for outside spraying on the thermoplastic paint; type three of the tiniest size is used for outside spraying on cold solvent paint.
