Glow in the Dark Powder Natural Red 40 g – Light by Day, Coloured Glow

Natural Red has a neutral, understated tint in daylight and releases the stored light in the dark as a warm, red-orange glow. It is suitable for accents that should not stand out during the day.

How to use the glow powder

The pigment does not dissolve; it is stirred into a carrier: epoxy and casting resin, clear varnish, acrylic paint, glue, wallpaper paste, wax or silicone. As a starting point we recommend approx. 20% pigment relative to the carrier; in opaque carriers such as white wall paint, rather 30–50%. Test the mixture on a small sample first.

• The more transparent and lighter the carrier, the stronger the glow. Prime dark surfaces in a light colour first.
• In thin resin the pigment sinks: let the resin thicken briefly, then stir it in.
• You can also sprinkle the powder onto sticky surfaces such as glue, wax or wallpaper paste, or apply it in clear varnish with an airbrush.
• For outdoor use, use weather-resistant clear varnishes or epoxy.

Good to know

A true red is technically not possible with glow pigments – the glow looks red-orange. For technical reasons, this shade glows clearly more weakly and for a shorter time than green or blue-green. In return, the surface stays light and inconspicuous by day. Afterglow is an aid for orientation and effects, not a light source: it becomes visible in real darkness and barely under a street lamp. Colours look different in photos depending on the camera and the charge. The raw pigment is not a toy. Avoid dust and contact with skin and eyes when processing larger quantities.
