PHOSPHORESCENT

PHOSPHORESCENCE PIGMENT

 

ITEM NO.:  Phosphorescence Pigment(Yellow Green:#6001C, BLUE: #6001B)

Introduction-

This series is a range of insoluble phosphorescent pigments with extended afterglows for general use in paints, plastics, inks and security applications.

These series pigments should not be milled or ground as this damages their crystalline structure leading to reduction in luminescent emissions, they generally have high density,
so liquid dispersions containing it should contain suspending agents to reduce hard setting.

The shelf life of this series is indefinite if stored in sealed containers, and they are generally considered to be of low toxicity when used as recommended.  However, contact with strong mineral acids should be avoided as this may lead to the liberation of hydrogen sulfide.

Injection instruction:

When applying with the plastic raw material, the plastic material has to be dry,

The effect is better if using small volume injection machine. It might result in the

darkening of product if the mixed material stays in the barrel too long.
