A. Glass Beads for Road Marking Huadong TM Glass Beads are suitable for Road &Line &Pavement Marking Paints. These glass beads are specially made for used in road marling paints and thermoplastic to provide excellent night retro-reflectivity. Type A is used as an intermix in the manufacture of reflective thermoplastic road marking paint. Type B is used as a filler for road marking paint. At night, as the vehicles headlight beam hits the painted line with glass beads, the beads act as tiny mirrors reflecting the beam back to the drivers eyes hence guiding him to drive safely. On road marking, Type A products are usually used in mixed use of the different size of the beads, when big beads which are normally on the top are worn out, small come out, thus maintaining the brightness of reflection. 1

Glass Beads for Industrial Use This product is suitable for high pressure sandblasting, abrasive, blasting and shot peening processes. Examples of usage are as follows: To clean moulds in die-casting, metal frog-ing, extrusion of glass,rubber and plastic. To debar flashing in electronic integrated circuit boards and frames and sealed plastic pipes. To clean deposits in piston chambers. To give a smooth and bright finish to surgical equipments and automotive parts. To clean the coil, rotor brushes and other parts of a generator during overhaul. To peen all types of glass and parts of integrated components of textile machine. To eliminate tensile stress increased fatigue resistance. Whether at work or play, Huadong TM Reflective Material helps you to be seen at dawn, dusk, or night, in all weather conditions. 3

In the process of storage and usage, glass beads whose surface is easy to be moisture is in humid atmosphere. It leads to light scattering, and therefore influences the direct reflection. Coated glass beads has better adhesiveness with road 4
coating material, particle sedimentation can be controlled after surface spreading through reasonable glass beads particle grading so as to ensure better reflection effect of the graticule.
