The principle of glow in the dark pigment powder is that it is energy from ambient light. It absorbs all kinds of visible light around, such as sunlight, lamps light, etc., and releases light in the dark. It can be understood as a transition of photoions, this leap process is a physical change, and therefore it has a service life of 15–20 years. The advantage of products made with Glow in the Dark Pigment over other types of products is that they are self-luminous and do not require an external electric source.

First, the glow in the dark pigment needs to be mixed with colorless transparent neutral media, otherwise, the glow in the dark pigment brightness will be covered.

Secondly, glow in the dark pigment is not grindable, because grinding will destroy the surface of the particles, resulting in glow in the dark pigment does not glow.

Thirdly, when using glow in dark pigment mixed with other media,avoid the use of iron in the mixing process, because the glow in the dark pigment particles are hard, and easily rub the surface of the iron.

Fourth, when using water-based media mixed with glow in dark pigment, be sure to use a waterproof version to prevent the use of non-waterproof glow in the dark pigment mixed with water-based media. when hydrolysis occurs, resulting in glow in the dark pigment does not glow.

Finally, because the specific gravity of glow in the dark pigment density is 3.6g/cm3, it is easy to sink, so it is recommended to use it immediately after mixing, otherwise， the glow in the dark pigment settlement will affect its use.

The glow in the dark pigment should be stored in a dry and cool place.

Non-waterproof glow in the dark pigment should be used up as soon as possible after opening， if don’t use it up, need to tie the bag tightly to prevent the glow in the dark pigment moisture absorption, because the glow in the dark pigment will be white and lumpy after absorbing moisture, this will cause the glow in the dark effect to diminish or disappear.
