We can supply glass microspheres on standard of different countries,such as AASHTO M247 EN1423/1424 and client's specifical requirement.
Highways Glass Microspheres
There microspheres 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 thermopiastic road marking paint. Type B is used as a filler for road marking paint.
