Road Marking Reflective Sand Blasting Clear Glass Beads
Glass Beads Description
High reflective glass beads, also known as retroreflective glass beads, are small spherical beads that are used in road markings to enhance visibility and improve safety.
The main purpose of using high reflective glass beads in road markings is to increase the visibility of road signs, lane markings, and other pavement markings, especially during nighttime and wet conditions.

Glass Beads Advantages:
-Does not cause dimensional change to the base material
-Environmentally friendlier than chemical treatments
-Leave even, spherical impressions on blasted part surface
-Low breakdown rate
-Lower disposal & maintenance costs
-Soda Lime glass does not release toxins (no free silica)
-Suitable for pressure, suction, wet and dry blasting equipment
-Will not contaminate or leave residue on work pieces
Glass Beads Application
-Blast-cleaning–removing rust and scale from metallic surfaces, removing mould residues from casting and removing tempering colour
-Surface finishing–finishing surfaces to achieve specific visual effects
-Used as disperser, grinding media and filter material in day, paint, ink and chemical industry
-Road marking
