Our luminous powders
With us you get the best luminescent pigments you can find on the market. Our offered professional luminescent materials/pigments are based on strontium aluminate and are characterized by an immensely higher and longer luminosity compared to the known, older luminescent powders (based on zinc sulfide). At the same time, our powders are absolutely non-toxic and free of questionable chemicals.
And: We only offer luminous powders that are tested and evaluated by us for the best possible luminosity (continuously).
There are hardly any limits to the areas of application: The luminous pigments are ideal as a base material for any creative activities such as painting, building, decorating, crafting and much more. Also interesting in the processing industry such as painters, varnishers, typesetters or (screen) printers.
Other possible uses include painted-on glowing stars in a child's room, noctilucent house numbers, escape route markings, fancy fingernails (glowing nail polish), jewelry, candles and much, much more.

Recommendation for use
The luminescent pigments are best mixed with colorless carrier fluids or binders (e.g. epoxy resin/resin, varnish, gel or wax). For interior use, solvent-free carrier fluids such as clear varnish or wallpaper paste are recommended. For exterior use, it is best to use weather-resistant and, if necessary, solvent-based binders such as synthetic resin paints.
Tip: Our offered pigments are very small, but the heavier/thicker the carrier, the less the pigments will settle.
We recommend a ratio of 1:2, i.e. 1 part pigment to 2 parts binder/carrier agent (i.e. approx. one third pigment/powder). The darker the carrier, the higher the proportion of pigment must be.
- Is the powder safe?
Yes. The pigments are absolutely non-toxic and free from hazardous chemicals or radioactive substances. According to DIN ... the material could even be used for children's toys.
- Why shouldn't I just buy cheaper powder?
Do not buy luminescent powders whose luminous duration will disappoint you. Based on so-called "strontium aluminates", our pigments are far superior to conventional and well-known phosphorescent materials in luminosity and luminous duration.
- Usage in color possible?
Yes, since the pigments are quite heavy and would settle, you need a correspondingly "thick" carrier liquid. We therefore recommend thickening thin paints before use or using another heavy carrier, such as clear varnish (or clear liquid plastic or clear casting resin). For painting and decorating, it is best to use acrylic paints, transparent or at least as light as possible, so that the glow is not darkened too much by the paint.
- Is the puver rechargeable?
Yes, the powder can be recharged at any time and by any type of light (e.g. sun, flashlight, etc.). We recommend sunlight, because the pigments are charged the fastest and strongest by UV radiation. The material has a durability of at least 15 years.
- How fine/coarse is the powder?
Depending on the information in the article description. With a particle size of our offered pigments in a range of approx. 55 to 75 micrometers (= under 0.008 mm), this is comparable to the diameter of human hair.

As a first step, perform a skin compatibility test on a 1 cm x 1 cm small spot on the arm, as everyone reacts differently to foreign substances. If no allergic reaction occurs, you can decorate your body without hesitation. To do this, mix the glow powders with special skin glue or adhesive fat cream.
An exception in the composition is the color pigment orange, because this is calcium sulfide, which is irritating according to the Ordinance on Hazardous Substances.
The phosphorescent professional color pigments store natural light and emit it again in darkness in a clearly visible way. Daylight, especially direct sunlight, is perfectly sufficient to stimulate the long-lasting luminosity of the colors. Electrically generated UV light (black light) can of course also be used for activation.
Depending on the product, charging via artificial light (light bulbs for room lighting and LED) is additionally possible (especially for blue-green and green).
Phosphorescent pigments are mixed with a carrier substance before application, which in the best case is clear and translucent. Then they can be applied directly.
Suitable is: casting resin, epoxy resin, tree resin, liquid plastics, wallpaper paste, transparent glue, hot glue, silicone, acrylic varnish, nail polish. Fixing spray, grease cream. For indoor areas, choose a solvent-free carrier. In the garden and, for example, for bicycles and cars, we recommend weather-resistant carrier liquid and sealing with an additional protective coating.
It is important that the pigments are not covered by darker / opaque particles, as in this case the luminosity is reduced. Test milky liquids to see if they become transparent during curing. In this case, you can use the pigments with them without any problems.
Mixing with other colors is generally possible with our professional products. However, the pigments should not be coated or covered by other colors, this would darken their luminosity. Observe the following instructions to maintain the luminosity in the best possible way: the lighter/ more translucent the other color, the more prominent the self-luminous color pigments will be. You can thin dark acrylic paints slightly and then incorporate the glow pigments with acyrl binder. You will get the best result if the noctilucent powders mixed with clear varnish are applied thinly to the painted picture. The pigments are whitish in daylight and appear like a slightly dusty layer on the painting when you look closely. However, the underlying color still stands out clearly.
Due to the pigments' own weight, they may sink into water-based paints. You can thicken the carrier liquid with clear varnish before sprinkling.
For painting on paper and wallpaper, prime with white acrylic paint so that the pigments remain on the surface of the material.
For painting textiles, mixing with normal fabric paints is not sufficient. We advise to use transparent screen printing inks.
The luminous pigments are water-resistant due to a protective coating, they can be used, for example, to illuminate decorative fountains, aquariums or swimming pools. Due to the weight, they sink down in the water and do not float in the liquid, as known from a snow globe. They shine a little weaker from the bottom, because the pigments there can absorb less light.
The offered Lumentics pigments are very high quality, the shades green and blue have an afterglow time of 8-12 hours. The pigment purple afterglows for 3 h and orange for about 1 h. The strongest luminosity is reached in the first half hour, then it gradually decreases. All pigments are guaranteed to be usable over and over again for up to 15 years and retain their properties.
Glow powders in the colors green and blue-green show the strongest afterglow effect. The blue pigments are less pronounced. The orange and purple versions radiate at a wavelength that is more difficult for the human eye to detect. Therefore, the luminosity appears lower than, for example, with the strongly luminous perceived colors green and blue-green. On dark backgrounds or as face paint, the purple-glow pigment stands out with difficulty. Mix in some blue-green powder if necessary.
The purple color pigment is very difficult to excite by light with a low UV content (e.g. an incandescent bulb).
The luminous pigments are supplied in a resealable bag and are white-yellowish in daylight. After charging, they glow in the dark in the desired color.
The premium glow powders are removable according to the description of the carrier substance. From textiles (without special fixation) and skin, the pigments can be removed well with soapy water.
The powders can be used over and over again for at least 15 years without losing their luminous properties.
The particle sizes of our premium annealing powders are 65-85 µm. This makes them ideal for incorporation into liquid binders. If you do not mix in our pigments but use them directly in the form of granules or as decorative pebbles, we recommend that you purchase our annealing granules.
The premium afterglow powders are ideal for use in hobbies, DIY, gardening, handicrafts, for beautifying walls and pictures - without having to rely on black light. Also in the safety area, e.g. for luminous signs, escape routes, bicycle helmets, etc., you can achieve the desired lasting luminous effect with the pigments.
The mixing ratio is ideally matched to the viscosity of the carrier liquid. A mixing ratio of one part glow powder to two parts carrier liquid (1:2) is appropriate in most cases. For dark mixed colors, you can sprinkle in slightly more luminescent pigments. The denser the pigment ratio, the stronger the luminosity. If the pigment ratio is too high, the mixture may form lumps. It is best to mix slowly while stirring constantly.
For incorporation into wall paint, the mixture of 1:1 - 1:3 is well suited, depending on the viscosity and brightness of the paint.
The mixed powders can be applied well with a narrow brush for fine drawings. Instead of one thick layer, it is better to apply several thin coats so that nothing runs. On useful surfaces (e.g. musical instruments, stair treads), seal the pigment layer with an impact-resistant transparent topcoat.
