Encapsulated vs. Not Encapsulated

Techno Glow provides both encapsulated and not-encapsulated glow powders in numerous particle sizes and colors. Encapsulated glow in the dark powders have a protective coating over the powder particle that makes it waterproof, while the non-encapsulated powders do not have the protective coating. The protective coating is of silicon hydride or other similar coating. 

This means that if you mix not-encapsulated glow powder into mediums like acrylic paint, acrylic latex, or many plastic resins and solvent based products you should be fine. The thing you have to pay attention to is if you were to mix the not-encapsulated powder into water or water-color paints (like children use in schools). If the not-encapsulated absorbs too much water then it can damage the powder. Most mediums dries fast enought where this might not be an issue.

Encapsulated powders may emit a slightly lower glow than the non-encapsulated, but not a significant issue for most users.

Powder Particle measured in Microns

We offer GreenAqua and Blue glow in the dark powder in various particle sizes ranging from 0 - 150 microns (µm).

The smaller the micron size the finer the powder which result in a smoother finish. Larger micron size powders usually glow longer and brighter. Check out the brilliance/luminosity data in each of our glow in the dark powder listings. In general, a powder size in the 50 µm range is best. Finer 5-30 µm or larger 75-150 µm sizes are right for specific applications/uses. 

Finer glow powders up to 30 µm tend to thicken most mediums and cause the mixture to dry out and harden. If you do use the finer powder with such mediums, mix just enough to use for a few minutes up to half and hour. Fine powder is mostly used for making ink, silk screening, watch dials and airbrushing. 

Glow Brightness/Brilliance measured in mcd/m2

Brilliance or luminous intensity measures how much light energy is emitted from a substance. The standard unit of measurement is a candela, or roughly the amount of light generated by one candle. For glow in the dark powder, the comparisons are reported using milli (1/1000th) candela per square meter mcd/m2.

There are national and international standards for how long a substance is exposed to light and how bright the light is, before you measure the brightness of the glow. Many providers use brighter lights or longer exposure to get better numbers. Techno Glow has some of the brightest and longest lasting glow ... following the requirements of the standards bodies.
