Glow Granules Orange-Red 1 mm, 100 g – Glow in the Dark

Fine glow granules for stirring into casting resin, varnish or glue and for scattering. They absorb light and release it in the dark as an orange glow – without electricity and as often as you like. The grain is dyed red by day and glows orange in the dark – a true red afterglow is technically not possible. Darkly dyed shades glow much more weakly and for a shorter time than green.

Properties

• Material: strontium aluminate doped with europium and dysprosium
• Grain size: fine, approx. 0.5–1 mm
• Afterglow duration: up to 2 hours after full charging in complete darkness; at its strongest in the first few minutes
• Colour: red by day, orange in the dark
• Temperature: dyed grain – do not heat above approx. 150 °C
• Classification: not classified as hazardous under CLP – see safety data sheet

How to use the glow granules

The granules are worked into a carrier or scattered loosely: epoxy and casting resin, resin, clear varnish, glue, grout, wax or silicone. Typical uses are river tables, resin jewellery and coasters, mould making and decoration.

• Casting resin: in thin, runny resin the grains sink. Let the resin thicken slightly, then stir them in and distribute quickly – or add the granules only to the top layer.
• Sprinkling: sprinkle onto still wet varnish, glue or resin and press lightly; protect smooth surfaces with clear varnish afterwards.
• Concrete, paving, joints: press into the still damp surface and sand flush after curing – or embed in a transparent, walk-on layer.
• Outdoors: work with solvent-based, weatherproof carriers such as epoxy or exterior clear varnish.
• The clearer and lighter the carrier, the stronger the glow. Prime dark surfaces in a light colour first.

Good to know

Afterglow is an aid to orientation and a visual effect, not a light source: it becomes visible in real darkness, hardly under a street lamp. The 1 mm granules are not waterproof: in water they gradually dissolve to a greater or lesser extent and the glow effect is lost. For use in or near water, embed the grains in resin or a water-resistant clear varnish – or use the 4 mm granules, in which the pigment is bound in synthetic resin. The granules are a craft material, not a toy.
