glow in the dark material particle size

However, due to the specific gravity of 4.1 luminescent pigment particle size is 19 --- 25um, it is necessary to be made ??of synthetic resin granules or pellets, and then used in processing . Standard ratio storing pigment incorporated into the resin is 10 to 20% by weight --- . The higher the amount of the phosphorescent pigment is realglow where to buy glow powder in the brightness . The ratio can be set depending on a use , cost, and other conditions . Phosphorescent pigment is the main component of the phosphor ZnS (ZnS: Cu). Avoid the use of resins and additives containing lead, cadmium , iron and other heavy metal ingredients. Since the phosphorescent pigment is pigments in paint a high temperature close to 1300 ℃ , so its thermal stability is relatively high . However, if they contain heavy metals described earlier , when there may be heat molded suffered accelerate its deterioration. In addition, the high acid value , then , over time , luminescent pigment will degenerate.
