Project Description


Glass Beads For Road Making Paint

The drop on glass beads will be evenly spread on the surface of the hot-melt paint at a certain ratio through the spray gun of the marking machine at the same time as the marking line construction.

Road marking glass beads are mainly used in normal temperature and hot melt road marking paints.


  • The specific gravity of drop on glass beads: 2.4-2.6g/cm3

  • Glass bead refractive index: ≥ 1.50

  • The roundness of glass beads: ≥80%

  • Magnetic particle content: ≤0.1%

  • The overall appearance of the glass beads is required to be colorless.

  • Loose spherical particles, clean and free of impurities

  • Not contain an Agglomerate
