Everyglow WLBSB series Photoluminescent pigment is a alkali-earth silicate base phosphorescent material, after coating a special layer on the crystals surface to giant the good performance water resistant, Everyglow WLBSB waterproof glow in the dark pigment available glow 8-12hours when absorb the visible light for 5-30mins,
and this emit & absorb light process 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.
