Glow in the Dark Powder Purple-Purple 40 g – Purple by Day

Purple by day and purple in the dark: this pigment is strongly tinted and adds a touch of colour even in daylight. After charging with UV light, it glows purple in the dark. Like all darkly tinted shades, it glows much more weakly and for a shorter time than green or blue.

Properties

• Material: strontium aluminate doped with europium and dysprosium, with a protective coating – which makes it water-resistant
• Afterglow duration: up to 2 hours after a full charge in complete darkness
• Colour: purple by day, purple in the dark
• Particle size: approx. 20–30 µm (1 µm = one thousandth of a millimetre)
• Charging: ideally with UV light or sunlight; normal room light only excites it weakly
• Temperature: tinted pigment – do not use above approx. 150 °C
• Classification: not classified as hazardous under CLP – see safety data sheet

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, runny resin the pigment sinks: let the resin thicken briefly, then stir it in.
• Outdoors, use weather-resistant clear varnishes or epoxy; indoors, solvent-free carriers such as clear varnish or wallpaper paste are suitable.

Good to know

Darkly tinted pigments are a colour and effect shade, not lighting. For a long, strong afterglow, green, blue-green or blue are better suited. The raw pigment is not a toy. When processing larger quantities, avoid dust and contact with skin and eyes.
