Glass Beads Description
Glass Beads are a spherical abrasive manufactured from chemically inert, lead-free, soda-lime glass with no free silica. machined and forged parts. Glass Beads produce clean, bright satin finishes, without dimensional change to parts, that are smoother than those produced by angular abrasives.
Technical parameters of glass beads for long-lasting rainy night high-brightness marking: refractive index: 1.5, density 2.4-2.6g/cm³, bulk density 1.7g/cm³. For high-end markings, please use our company's glass beads as internal glass beads, which can maintain long-term effect and high resistance.
Advantage
1.High reversibility. Use this product in hot melt coatings to maintain a high reversal state for a long time.
2.low spreading rate
3.High wear resistance
