Q1 - What makes your material glow? Is it safe? Is it radioactive? Is it toxic?
A1 - The material absorbs and store light energy then emit light in the dark.
The material is free of radiation, non-toxic. And YES, it is safe for humans and the environment.
Q2 - How long your pigment can glow?
A2 - Depends on what we define "glow." Under norm DIN67510 part 1, the brightness that is higher than 0.32mcd/m2 (which is 100times of a threshold of human eyes' sensibility to light) is defined as "glow."
Under norm DIN67510, the pigments glow more than 20hours; some items even glow for weeks.
Q3 - How bright of your pigment?
A3 - The glow brightness of pigments is different from each other. Generally speaking, the larger pigment particle size, the brighter; Color-dyed glow pigments will lose some brightness, the darker, the lower of brightness. Taking TPY-6C as an example, in a closed dark room, use a D5 x H8cm glass tube to containing the pigment. At 10cm distance, by the pigment's light, 12# Times New Roman characters are readable for about 2hours; At a 3meters distance, the pigment is visible for 12+hours.
