LONG LASTING GLOW IN THE DARK

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
Pigment Long Lasting Glow in the dark
B. Long-lasting Glow Powder (Strontium Aluminates type)
a. Product Description
Pigment Long Lasting Glow in the dark The density of long-lasting glow powder is 3.6. It’s made by strontium aluminates, which is non-toxic and non-radioactive.
b. Properties
Pigment Long Lasting Glow in the dark 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
Pigment Long Lasting Glow in the dark For solvent based ink/paint 5%~30% w/w(25%) 
(For the best result, about 25% concentration is required for 20um film thickness)
Pigment Long Lasting Glow in the dark 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
Pigment Long Lasting Glow in the dark Avoid moisture during processing. 2. Avoid direct contact with metals. 3. Avoid frictions at high temperatures.
Pigment Long Lasting Glow in the dark 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.
Pigment Long Lasting Glow in the dark 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.
C. Conventional Glow Powder (Zinc Sulfide type)
a. Product Description
Pigment Long Lasting Glow in the dark Made by Zinc sulfide, the density of conventional glow powder is 4.1, having shorter afterglow time.
b. Properties
Pigment Long Lasting Glow in the dark Conventional glow powder is pigment, suitable for plastic injection and solvent /aqueous based ink/paint, having brighter start glow.
c. Recommended Concentrations
Pigment Long Lasting Glow in the dark For solvent/aqueous based ink/paint 5%~30% w/w(25%) 
(For the best result, about 25% concentration is required for 20um film thickness)
Pigment Long Lasting Glow in the dark 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
Pigment Long Lasting Glow in the dark Please refer to long-lasting glow powder for recommendations on paint/screen printing ink applications.
Pigment Long Lasting Glow in the dark Guidelines for applications of plastic injection/extrusion:
◎Use plastic of light-color, fluorescent-color, or transparent-color as the base plastic for the best glow strength.
D. Microcapsulated Glow Powder
a. Product Description
Pigment Long Lasting Glow in the dark Encapsulated long-lasting glow powder by polymer can avoid oxidation destroying the glowing properties of the powder, which makes it suitable for aqueous based applications.
b. Properties
Pigment Long Lasting Glow in the dark Microcapsulated glow powder can be directly applied to aqueous based ink/paint.
c. Recommended Concentrations
Pigment Long Lasting Glow in the dark For solvent/aqueous based ink/paint 5% ~30% w/w(25%) 
(For the best result, about 25% concentration is required for 20um film thickness)
d. General Recommendations
Pigment Long Lasting Glow in the dark Please refer to conventional glow powder for recommendations on paint/screen printing ink applications.
E. Glow-in-the-Dark Masterbatch
a. Product Description
Pigment Long Lasting Glow in the dark Glow-in-the-Dark masterbatch is made by mixing plastic and long-lasting glow powder, which can prevent glow powder turning dark due to oxidization when applied to plastic injection/extrusion.
b. Properties
Pigment Long Lasting Glow in the dark Dispersed and used easily, can be directly applied to plastic injection/extrusion.
c. Recommended Concentrations
Pigment Long Lasting Glow in the dark For plastic injection/extrusion 0.1% ~5% w/w(0.5%) 
(For the best result, about 0.5% concentration is required for 0.2cm plastic thickness)
d. General Recommendations
Pigment Long Lasting Glow in the dark Use plastic of light-color, fluorescent-color, or transparent-color as the base plastic for the best glow strength.
4. Miscellaneous
A. Particle size conversion: 100type(D50)=115um, 200type(D50)=69um, 300type(D50)=36um, 400type(D50)=23um.
B. Fluorescent agents, dye, or pigments can be added to the glow powder to adjust its before glow/afterglow colors. The powder can also be mixed to each other to get the glow color desired. Too many pigments added may diminish glow.
5. Others
A. Storage: Keep sealed in a dry and cool place. Do not use metal containers. Moisture in the air will shorten its shelf life and destroy glow property. Best within two years if stored correctly.
B. Safe for food grade packing and toys.
