1. Introduction
Glow in the dark materials can absorb and store light/heat energy, then glow in the dark. They can be recharged and continue glowing unlimited times as long as they get recharged sufficiently. The materials can be charged faster by exposure to sunlight/UV light.

3. Applications
A. Available Products & Applicability
B. Long-lasting Glow Powder (Strontium Aluminates type)
a. Product Description
The density of long-lasting glow powder is 3.6, It’s made of strontium aluminates, which is non-toxic and non-radioactive.
b. Properties
The long-lasting glow powder is pigment, suitable for plastic injection and solvent based ink/paint. Its afterglow time is ten times longer than that of the conventional type. Good weather resistance, applicable to both outdoor and indoor.
c. Recommended Concentrations
For solvent based ink/paint 5%~30% w/w(25%)
(For the best result, about 25% concentration is required for 20um film thickness)
For plastic injection/extrusion 5%~15% w/w(10%)
(For the best result, about 0.5% concentration is required for 0.2cm plastic thickness)
d. General Recommendations
Avoid moisture during processing. 2. Avoid direct contact with metals. 3. Avoid frictions at high temperatures.
Guidelines for applications of paint/screen printing ink:
◎Use neutral or weak alkaline clear resin
◎To avoid precipitates of glow powder occurred in glow paint, use high-viscosity resin and add an anti-precipitation agent to the paint. Stirred well before use. Add thinner if necessary. Do not add any heavy metal compounds.
◎Use white, or light color as a background for the best results. Any color other than white will diminish glow.
◎Use a 80-120 mesh screen for screen printing for the best results.
Guidelines for applications of plastic injection/extrusion:
◎When applying long-lasting glow powder directly to plastic injection/extrusion, it is recommended to add some lubricants to mix well and prevent oxidation.
◎Make the long-lasting glow powder processed in cylinders as short as possible.
◎Use plastic of light-color, fluorescent-color, or transparent-color as the base plastic for the best glow strength.
