Glow in the dark luminescent pigments must first absorb all kinds of visible light to store light energy, and then they can automatically emit light in the dark, and can be used indefinitely.

Should pay attention to in use:

Need to use neutral or weak alkaline transparent resin, mixed use;

Need to stir and disperse raw materials at high speed, preferably in glass or ceramic containers;

The length of storage time depends on the amount of moisture, so pay attention to moisture resistance.  The moisture is too high, and it is easy to turn black or lumpy;

To reduce the precipitation of glow in the dark powder, use a high viscosity resin, or add anti-settling agent, and stir well before use.  Diluent can be used to adjust the viscosity, and heavy metal compounds cannot be used as additives;

In order to improve the brightness and luminous time of printing, the printing background should be mainly white or reflective color system;

Screen printing, in order to obtain better luminous effect, the mesh is best with 80-120 mesh; the thickness of paint and ink is not less than 100um, if it can reach 130-150um, the effect is best (use 80 mesh screen, print twice to reach this thickness);

The recommended amount of luminous powder is 10% -60% of the total weight. The more the amount, the better the luminous effect;

Choose different types of transparent inks according to different printing materials. For example, the printing material should be selected for metal, and the PVC materials should be selected for PVC. The higher the transparency, the better the effect.

If water-based coatings and inks are required, the luminous powder must be coated with special microcapsules to be durable.
