P2453BTA - Retroreflective Application Instructions


P2453BTA are solid, barium titanate glass microspheres with a 40 - 50 micron typical mean diameter, a tight distribution, with an upper size of <100 microns. The microspheres incorporate a hemispherically coated aluminum shell on one side to provide maximum retroreflection. In bulk these metallized glass spheres appears as a grey powder. Under a microscope, each the microparticles can be seen to be a partially aluminum coated spheres.


    Available as dry powder with the following 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
