Application Instructions for Retroreflective Spheres
P2453BTA metallized spheres product line consists of solid, barium titanate glass microspheres with a 40 - 50 micron typical mean diameter, a tight
particle size distribution, with an upper sphere diameter of less than 100 micron. The microspheres incorporate a hemispherically coated aluminum shell which provides maximum retroreflection. In bulk, these metallized glass spheres appear as a grey powder. Under an optical microscope, each individual microsphere displays a partial aluminum coating.
