P2011SL are the smallest glass microspheres made from recycled soda lime glass and manufactured to meet a tight distribution curve. Average diameter is between 3 and 6 microns, with a top size of 20 microns. The P2011SL is primarily used in applications where the film build is so thin, such as automotive paint, that only this small a sphere can fit without protrusion. The P2011SL is also used in the cosmetics industry to diffuse reflected light in products such as powders and foundations, and to reduce the “glazing” that hardens or cakes powders after exposure to face oil.

P2015SL are soda lime glass microspheres that improve clarity of color, creating a multi-dimensional effect when they surround pigments or metallic additives. The P2015SL microspheres have a mean size of 8 to 12 microns , and a top size of 36 microns. The P2015SL spheres can be incorporated into solvent or water-based paints and coatings, plastics, inks and certain cosmetic formulations.

P2050SL is designed to be another “work horse” product, with the broadest particle size distribution providing the same benefits of color enhancement and consistent color from any viewing angle as smaller spheres, but its larger average diameter of 35 to 45 microns makes it effective as an anti-mottling agent and flow enabling ingredient in heavier or thicker film coatings or paints such as latex architectural paint (Product was previously P/N P2043SL).

P2075SL shares the characteristics of the P2050SL, but has a larger average diameter of 65 to 75 microns . Its larger average diameter promotes the use of the P2075SL as a flatting agent in industrial applications, such as paints or coatings, where a matte appearance is desired.

Bulk grades of solid soda lime glass microspheres are 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 (F22) - NEW FORMULA (P2011/P2015 ONLY) - for improved hydrophobicity to bring the spheres to the surface in solvent based systems
  • Fluorochemical Coating (F35) - NEW FORMULA (P2050/P2075 ONLY) - 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
