UVLWG - Ultraviolet Longwave green fluorescing non-soluble powder.

  • Excitation: 380nm peak
  • Emission: 518nm peakParticle Size (50%): 4 microns

UVLWR - Ultraviolet Longwave red fluorescing non-soluble powder.

  • Excitation: 360nm peak
  • Emission: 628nm peak
  • Particle Size (50%): 5 micron

UVLWB - Ultraviolet Longwave Blue fluorescing non-soluble powder.

  • Excitation: 350nm peak
  • Emission: 450nm peak
  • Particle Size (50%): 5 microns

These substances

  • Will not degrade under UV light,
  • Are highly fluorescent
  • Can withstand heat over 1500 DegF
  • Have very low visibility under normal light
  • Particle size of less than 10 microns
  • Will not dissolve in solvents


High Visibility UV Non-Soluble Phosphors



These superfine powders can be used as a pigment in paints, dusted on surfaces or mixed in solution.  Powder weight is 28 grams.

  • Non-Toxic
  • Highly visible under normal light
  • Highly fluorescent under ultraviolet (365nm) light
  • Non-Reactive
  • Good long term stability

Useful For:

  • Painting gauge needles and numbers
  • Dusting surfaces for fingerprint analysis and detection
  • Theft detection
  • Scientific experiments
  • Finding air leaks and visualizing air movements


These powders are water washable, but can be difficult to wash out / off completely.  It is very easy to make a big mess with just a tiny bit of powder, so be careful!  Just a small bit of powder goes a very long way.  Please test an small amount of powder first.
