HOW DOES GLOW IN THE DARK WORK?

Anything that glows in the dark is known as phosphorescent or photoluminescent.

Phosphors are chemicals that collect energy from light and store the light energy for some time making them glow for hours afterwards, even when the light source is turned off.

All our phosphorescent products are made using a high grade phosphor called strontium aluminate. This high strength strontium aluminate releases energy more slowly than some other phosphors, making some of the brightest and longest lasting glow-in-the-dark smart materials on the market.

Charge our glow products in UV light first to make them glow in the dark. The longer they are charged, the longer they will hold glow. You can achieve up to 10 hours of glow time!

WHAT CAN I MAKE GLOW IN THE DARK?

You can use SFXC glow in the dark powders and inks in lots of different ways.  Some glowing examples include:

Solvent based pigments and plastisol inks

  • Resin and paint applications
  • Screen Printing

 Water treated pigments

  • Fashion, canvas apparel
  • Halloween products 
  • Paper crafts

WHAT CAN I MIX GLOW IN THE DARK POWDER WITH?

Our glow powders can be mixed with clear mediums like resins, varnishes and lacquers. It is always recommended to add your chosen medium to the glow pigment rather than the pigment to the medium.

Try to avoid making large batches. Make the product as and when you need it to prevent the particles settling. Always remix the coating before reusing.

If possible, please use a viscous (thick) medium.  The glow particles are heavy for their size, and they tend to settle rather quickly.

The medium must also have low acidity. High acidity will damage the glow. You can check this with the manufacturer of the medium you are using.

When mixing glow pigments in with your chosen medium, please avoid grinding or sheer force as this can damage the crystals and destroy the glow.

HOW MUCH GLOW POWDER SHOULD I USE?

Mixing ratios can be adjusted depending on the application. Please check what is recommended by the manufacturer of the medium you are using.

You can use 6% pigment load, but 10% pigment to 90% medium is usually sufficient. The more pigment you add, the stronger the glow.

WHAT CAN I USE TO MIX MY PIGMENTS AND POWDERS?

We recommend using plastic spatulas and mixing bowls. Avoid using metal mixing equipment as this could react with the glow pigments.

WHAT SHOULD I USE AS A BACKING COAT?

For the best results, it is always best to apply the finished glow coating to a light or white background or basecoat. A dark background or basecoat will deplete the glow.

Please avoid using coloured mediums when producing a glow in the dark coating. A transparent medium is needed to increase the brightness of the glow.

ARE GLOW IN THE DARK PRODUCTS SAFE? 

If handled with the appropriate equipment, our glow in the dark products are safe to use in creative applications. However, they not cosmetically certified so should not be used for makeup, applied to the skin or put in the mouth. Please dispose of waste or used product via methods outlined in the safety data sheet linked at the on each product page.

HOW SHOULD I APPLY GLOW POWDER?

Apply using a brush, paint roller or by screen printing.

A thin layer of glow coating will not perform as well as a thick layer. A heavier build (coating thickness) is required to increase the glow time and brightness.
2-3 coats may be needed to increase the glow.

Always ensure the coating is applied to a dry surface and free from debris.

Once the coating is dry, use a clear protective top coat for extra durability.
