Product Description:
Our PPWB-00 Invisible Blue phosphorescent pigment was developed to go into oil or water based mediums. Phosphorescent pigment is the basic building block for material that glows in the dark. It works by absorbing ambient light and then re-emitting it in the visible spectrum. This process can be repeated an infinite amount of times. The color visible in regular light is an off white and it will glow a vibrant Blue in the dark. This "change" of color is why we refer to it as invisible. You can mix this pigment into any clear medium such as glue, paint, caukling, wax, clay, gel candles, liquid nails, silicone, urethane, you name it.

Glow Time Chart Measured in mcd/m2
The afterglow brightness is measured under D65 standard light source excited by 1000 lux for 10 minutes. The excitation wavelength is 253.7 nm. The instrument to determine brightness LS-100. As a general rule, the larger the particle size the greater and longer the glow. The threshold of the human eye to detect light is .32 mcd/m2 with a dark adapted eye.

How to Use:
This product is easy to work with. Simply mix it with a clear medium such as clear paint, clear glue, clear wax, etc. and you will have a glowing material! Follow the guidelines below to ensure you maximize the glowing effectiveness of our product.

1. More powder, higher percentage will produce brighter, longer glow.
2. Use a white, or light color as a background for best results. Any color other than white will diminish glow.
3. Use the clearest vehicle possible. Any pigment in the vehicle will decrease the brightness and length of glow.
4. The thicker (to a point) the layer of Glow Powder will produce longer and brighter luminosity.
5. Try to prevent moisture in the manufacturing process.
6. Do not use vehicle with high acidity.
7. Do not grind the Glow Powder, it will destroy the crystal structure and therefore decrease luminosity.
8. The larger the particle size of the Glow Powder the greater the glow.
9. Ratio of Glow Powder to medium is from 10% to 50% by weight depending on application and manufacture process. Best to start with 30% and move and down depending on cost, manufacturing process, and other factors that are unique to your application.
