Glow Granules Yellow 1 mm, 100 g – Glow in the Dark

Fine glow granules for stirring into casting resin, varnish or glue and for sprinkling. They absorb light and release it again in the dark as a green glow – without electricity and as often as you like. The grain is tinted yellow by day and glows green in the dark. For technical reasons, tinted shades glow weaker and for a shorter time than untinted green.

Properties

• Material: strontium aluminate doped with europium and dysprosium
• Grain size: fine, approx. 0.5–1 mm
• Afterglow duration: up to 4 hours after full charging in complete darkness; strongest in the first few minutes
• Colour: yellow by day, green in the dark
• Temperature: tinted 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 sprinkled 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 briefly, 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; then protect smooth surfaces with clear varnish.
• Concrete, paving, joints: press into the still-wet surface and sand flat after curing – or embed in a transparent, walk-on layer.
• Outdoors: process 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 for orientation and effects, not a light source: it becomes visible in real darkness, but barely under a streetlight. The 1 mm granules are not waterproof: in water they dissolve to a greater or lesser extent over time, 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.
