Techno Glow in the Dark & UV Reactive Powder - Multipurpose PRO-Series - Natural Green - 1 Ounce (28g)

Charge quick and bright longer. The powder mix well in the resin. Under UV light 15 to 30 seconds the brightness last for several minutes. The shine go to zero after several hours. I have tried with several but so far this is the best.

This powder glows VERY bright! It is incredible, I stuck the bag under UV light for 30 secs after I recieved the package and took the first picture. Its glowing bright enough you can see the details of my hand. But, I bought this to add to a 3d resin printing project. The particles are too heavy, instead of being suspended in the resin evenly the glow powder sinks to the bottom of the vat. The first few layers of the print will lift the glow powder, but everything underneath won't get any powder after that. So the first few layers of the print will glow super bright, but the rest of the print will only have a small amount of powder. In my particular case this worked out, because I only needed one side of the print to glow, you can see in the second picture the top glows brightly, but the middle and back are really only being lit up by the glow from the top layers. If you are looking at this and thinking about adding it to a resin print, I would suggest looking for a different solution. Finding a powder with a finer/lighter particle size would be ideal, but thats not really info that many manufacturers release. Personally I will be trying glow-in-the-dark alcohol based inks next, as well as picking up some premixed glow resin. If you are still thinking about this for a resin print (Good for you! Experimenting is fun!) then I have one last bit of advice: make sure you have a fresh FEP film on hand, because this powder will scratch up the film in your vat. Also don't dump the powder contaminated resin leftovers back in the bottle, it will contaminate the whole bottle. Probably shouldn't put it in your resin left-overs bottle either, just try to keep it seperate from everything else really. So 5 stars because it is an insanely bright glowing powder.

Good to work wit.

This is a good product. Really. I have searched and searched for the perfect powder and this is as close as I’ve gotten so far. The brightness is amazing and the color is a icy white blue. Very lightweight and quick to mix with just a few tips below. 2nd best powder for longevity of glow. Very nice. 3 Hint(s): Warm the liquid before you add it to the powder. Yes, add the liquid TO the powder to avoid clumping. Don’t grind it or it will lose the ‘glow’ effect. Scientifically.... Somehow. I read it somewhere so it’s definitely true.

Haven’t actually used it in the application I bought for but the intensity of the glow & for the amount of time is mind blowing. This is with the bag just sitting on my kitchen counter. Can’t wait to actually use it

Love this stuff, used it on a project I did on my countertop 3 years ago and still looks fantastic

this stuff really works well. mixed with matte gel medium (and later with acrylic paint) to decorate plastic skull and it's amazing how bright it can be. one issue is it really needs to be exposed to light quite well so think about how you're using it. takes some work to mix smooth. a little goes a long way. would order again as it's better than any glow-in-the-dark paint I've ever used.

The tumbler that is pictured, was never supposed to be a beach/ocean themed tumbler. Unfortunately, after mixing the product relentlessly, and then applying the top coat to my glitter, this powder settled down and looked like a layer of sand over my glitter, nearly ruining the whole project. Fortunately I had the thought of it looking like sand and was able to salvage the project some. For the theme, it worked out great, but knowing it does not actually mix and dissolve at all, I feel this was a waste of money. I do not do beach themed tumblers normally, so I cannot even just keep this for those types, so for me, it is essentially useless. It would be great for people who like to make beach themed cups, but not my personal cup of tea. The glow, when it does charge is impressive, but, and it's a big but, it is absurd how long it takes to charge, and how easy it is to disproportionately charge it as well. This was a huge disappointment for me, especially after searching for hours to try and find a decent glow powder. Just the fact it does not mix or dissolve at all with epoxy or crystalac etc, was enough for me to decide I would never purchase again. There are others out there that do, so I will search there.
