About Glow in the Dark Pigments

Photoluminescent Pigments

Photoluminescent pigments will absorb high energy light sources like sun light, day light or powered light and then re-emit this energy as low energy light over a long period of time. The better pigments for example will emit over a 12 hour period or more. The ability to store and release this light is automatic and repeatable with no need to start or set off a reaction in order to obtain the photoluminescent glow. This cycle of absorption and emission can continue until the host body has either yellowed or deteriorated to the extent that the individual particles are no longer working as a cohesive unit. These pigments are non-toxic, harmless and non-radioactive.

Where can glow in the dark pigment be used

The use of glow in the dark pigment is growing as this still relatively new technology is discovered. Their main use however is in applications where outside or interfering light is not a concern or can be controlled. For example homes, sheds, warehouses, public buildings, motor homes or caravans. Outdoor use of glow in the dark products is very limited and you would need to have a product with a very strong after glow to have success in this area. My glow numbers are a good example of an outdoor product that can work brilliant in the right outdoor environment.

Colours of glow in the dark pigment

Different colours have unique glow times and strengths. As a general rule yellow/green pigment is the brightest followed by Aqua then Blue then Orange and at the lowest Red. However I have developed technology to use Aqua and Blue at the same high levels as Yellow/Green so this is not a fixed rule. When selecting a colour for glow in the dark pigment it is advisable to refer to the manufacturer table as seen in my article how to select the correct glow in the dark pigment. This shows the after glow strength for the colour chosen so making it easier to select a correct pigment for a given project.
