Everyglow WLBG Waterproof photoluminescent pigment yellow-green

Description

Everyglow WLBG Waterproof luminescent pigment is a Rare earth strontium aluminate base glowing material, process a special waterproof material coating of the crystals surface, to make it with performance water resistant. it available glow more than 24 hours after absorb the visible light for 5-30mins,

and this emit & absorb light process is repeatedly,no power request.

Products Properties:

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.
