Everyglow Photoluminescent pigment is a rare earth strontium aluminate base lumnous material, which have 3otimes afterglow than traditional zinc sulfide base luminescent material.This type luminous pigment can glow 10-12hours after absorb the visible light for 5-30mins, and this emit & absorb light proess is repeatedly,no power request.
Free of radioactive elements , non-toxic, harmless, Eco-friendly material.
Longer afterglow time and super higher luminance than traditional ZnC sulphur luminecent material.
Excellent heat resistance . Good performace for temperature as high as 800℃
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 30years 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 , P-purple , SB-sky-blue.
1kg/bag, 25kg/drum, 500kg/pallet.
These pigment is mainly applicable as an additive in the paints, coating, ink, plastics,glass,ceramic, fibre and other transparent medium to realize it self-luminescent function.
