Glow in the dark paint in its simplest form is - the addition of glow in the dark powder to clear paints. It is very easy to produce either water based or solvent based glow in the dark paints in this manner.
The problem lies in finding the right chemical mixture and properties to have a decent product life. Unlike other mixtures, glow in the dark pigment which is made from crystals, do not disolve, but has to stay suspended in order to work. Because of this, the glow particles tend to sink to the bottom when mixed with most paints, solvents or water based.
We have managed to produce a suitable pre-mixed solvent based glow in the dark paint which has a decent shelf life of at least 6 months.
It is easier to work with solvent based than water based because solvent based mixtures are easier to re-mix. Glow Pigments mixed into water based carriers sink to the bottom and harden. Which is why there are no suitable water based glow in the dark paint, which can be pre-mixed and stored for months. It must be used immediately.
We are still working on a suitable water based solution for glow in the dark pigments. Till then, our water based glow in the dark paints will always be packed seperately; (Glow powder and water based solution)
