Everyglow WLBP Series luminescent pigment is from Rare earth Neodymium oxide base photoluminescent pigment after coating a special waterproof layer on crystals surface,so WLBP have the good water resistant Properties, Daylight appear to colorless, after absorb the visible light for 5-30mins, glow exceed 5~8hours with purple color.
Free of radioactive elements , non-toxic, harmless, Eco-friendly material.
Longer afterglow time and super higher luminance than traditional ZnC sulphur luminecent material.
Perfect light resistance. under 300W high pressure mercury lamp for 1000hr even not reduce them luminance.
High chemicals stability. Everyglow PL pigment not reaction with any organic and inorganic agents except mercury.
Long life time. as long as 30 years life time.

1) Excited by light source D65 1000Lx for 10mins;
2)The afterglow time indicates the time during which the pigment decline to 0.32 mcd/m2
3) The error about ± 10% is allowed in above data.
4) Color: G-yellow-green , B-aqua , Y-yellow, P-purple,O-orange,W-white
1kg/bag, 25kg/drum, 500kg/pallet.
These pigment is mainly applicable as an additive in the paints, coating, ink, plastics, and other transparent medium to realize it self-luminescent function.(Suggest waterbase paint,ink,plastic,silicon).
