Glow In The Dark Powder FAQ
Glow in the dark pigment is also called Photoluminescent Pigment. It can absorb all visible light, such as UV light, sunlight, lamplight and etc. It is like charging, then release the light in the dark.
All visible light can be absorbed by glow in the dark pigment. UV light and sunlight is the best light source
It can be mixed with transparent and colorless medium, such as lacquer paint, ink,?resin, rubber, silicone, plastic,glass, ceramic. etc. For?water?base?liquids,?water resistant pigments?are?applicable.
Absolutely, the powder is non-radioactive, non-toxic, and environment friendly. We have EN71-3 certificate to confirm that.
The glow effect depends on many factors. Such as surrounding brightness, addition rate, the particle size, light source, etc. Different condition different glow effect.
Such as using in outside, it will be affected by the moonlight and lamp, so the glow effect must different with using in all dark environment.
Glow in the dark pigment can be mixed with a transparent and colorless medium, such as paint, ink, resin, rubber, silicone, plastic, glass, ceramic, and etc, but not touch strong acid and alkali.
Glow in the dark pigment brightness depends on the particle size. The bigger the brighter. For example, 100-micron glow in the dark pigment, the initial brightness data is around 14,000 mcd/m2, and 100 mcd/m2 at one hour later.
Under Germany Standard DIN67510, the photoluminescent pigment can glow 8-12 hours depending on different grades.
No. The glow in the dark pigment will release 99% brightness in the FIRST hour, then keep a visible light for the rest hours.
Yes. glow in the dark pigment is non-radioactive, non-toxic, and environment-friendly. We have passed EN71-3 Environmental Standards test.
It is 15 years minimum.
Yellow-Green: SrAl2O4:Eu,Dy
Blue-Green: Sr4Al14O25:Eu,Dy
No. If ground, the particle surface will be damaged, It will not glow anymore. We have a different particle size from 15 microns to 800 microns for different usage.
Waterbased Glow in The Dark Coating FAQ
It needs to be mixed with the TRANSPARENT medium, the more transparent, the better.
Do NOT touch with STRONG ACID and ALKALI. Keep the PH value at 5-7.
The lifespan of glow in the dark pigment is 15 years, but for Glow in the Dark Coatings, it depends on the lifespan of the transparent coating.
Do NOT touch with IRON when dispersing, but stainless steel is ok. The dispersing speed is the slower the better.
Suggest using immediately after mixing. If have to put for some days, make the viscosity to 120-150KU. When using it, add some thinner in, mixing and use it in a short time.
We have solvent based pigment and water-based pigment.
