 Retroreflective Aluminum-Coated Solid Barium Titanate Glass Microspheres ~4.5g/cc - 30-100um
 
  
Description
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.
Also see other Barium Titanate Glass Spheres.
P2453BTA is a product of Prizmalite distributed through Cospheric LLC.
 
 
Specifications 
The spheres are offered in dry powder form with the following coating options:
·  Uncoated - no surface treatment
·  Silane Coating (S2) - for improved dispersion in aqueous systems (~76 degree contact angle)
·  Fluorochemical Coating (F35) - NEW FORMULA - for improved hydrophobicity to bring the spheres to the surface in solvent based systems
·  Fluorochemical Coating (F1) - RETIRED FORMULA - for improved hydrophobicity to bring the spheres to the surface in solvent based systems
