1.Photoluminescent Pigment
The photoluminescent pigment is made from rare earth
elementsthrough a hi-tech process. It absorbs light(natural day
light orelectrical lamp light) for about 10~15minutes and then
emits avisible light for more than 12 hours in the dark. It is free
ofradioactive and toxic materials and it is chemically stable.
Itcan be added into paints, inks, plastics and makes
themluminescent.

Particle size:100 mesh~400 mesh
2.Photoluminescent Safety Signs
The photo luminescent safety signs are printed with
thephotoluminescent pigment, which absorbs light (natural day
lightor electrical lamp light)for about 10~15 minutes and then
emits avisible light for more than 12 hours in the dark. It is free
ofradioactive and toxic materials. The photoluminescent safety
signsdo not need electricity. They are energy saving, easy to fix
andhave no failure in its function. The photoluminescent safety
signsare widely used in modern public buildings, hotels,
subways,stadiums and military bases.
