luminescent sheets continue to light more than a few hours

Realglow photoluminescent pigments heat resistance, surface abrasion resistance , suitable for all kinds of paper , textiles , wood, plastics , metals , ceramics and other materials are .
Luminous and luminous ink preparation method :
   Luminous transparent resin applied to neutral
   Selection of c -type 20-40, d -type 10-15,photoluminescent films , such as smaller particle size 5-10 luminous paint.
   Phosphorescent pigment is generally used in an amount of 30-50 % of the total , or to determine the amount of the pigment according to the luminous emission luminance requirements.
