This is not for fingernail extensions. It is a fine acrylic powder offered as a material for experimentation in coating or casting acrylic modified resins for jewelry or crafts. It is normally mixed with an acrylic monomer liquid which causes it to harden into acrylic resin. The acrylic powder is harmless as a solid powder, not so with the liquid monomer. We do not wish to list the liquid monomer we have because of the flammability and hazard warnings that come with it as a liquid. We will sell it in a custom listing if you request it. But, liquid acrylic monomer is not always necessary, you can use this powder as a filler/modifier for epoxy resins or cyanoacrylates (CA glue or "super glue"). We have included 2 "single use" tubes of CA glue to test it with. Be careful that you understand how the nozzle extension and cap system works so you don't accidently glue your fingers together. There is a thin and thicker CA included. The thin is notorious for dripping where you don't want it to go (on your fingers) if you're a novice at using "super glue". Mixing it with the acrylic powder makes a great "delayed set positioning" additive for CA. It acts differently with different types of CA , for example the very low viscosity as opposed to the thicker, higher viscosity (see below).

You can purchase the monomer separately from acrylic fingernail suppliers or dental resin suppliers who are used to dealing with it. Experimentation in coatings could also be undertaken with other resinous ingredients. For example, what would be the result in dissolving it alone in toluene like the Paraloid acrylic copolymer B-72? What would its properties be? Would using it as a modifier mixed with B-72 and/or Butvar 90 be feasible for modifying those resin's properties (hardness, rigidity, flexibility, adhesion, etc)? It is also possible to experiment with acrylic castings (acrylic monomers can be cast into thick sheets, but it is notoriously difficult because of exothermic heat and shinkage).
Would it be possible to make much smaller and less difficult DIY castings by combining it with cyanoacrylate which mixes with and hardens the acrylic powder?
I have been mixing the powder with thin CA for some time now, but I have not tried to make castings. I think bubbles would be an obstacle to overcome even in very small castings.

Here's what I currently use it for, it is an example of one use for this acrylic powder. I combine CA/acrylic powder to make a glue I particularly like. The process which I use is not new. The easiest method is to simply drip some CA thin glue onto the powder which is sitting on top of one surface to be glued, or might be placed into a crack or void. It doesn't take much CA to just wet the powder (short of making a "soupy" blend). Then, if gluing two surfaces together, the 2nd surface is simply placed on top of the wet powder. It may need support or clamping to maintain a certain position while it's setting which takes about 3 minutes.
I find that the fact that the glue blend stays "liquid" for a few minutes is a very great advantage in many cases since it gives you time to re-position the surfaces, it doesn't instantly set up into some off-kilter joint and then need to be re-done. I don't want "instant". It also gives you time to wipe up any glue blend that's oozed out of the joint. Leaving a bit of the glue outside the joint in a "fillet" is actually a great strength enhancer for the bond.
Another point which I like about this method is that the glue blend sets up completely through and through, filling any large gaps that may exist in the joint between surfaces.
And lastly, I like the slight flexibility this glue blend has. When it first sets it is *very* flexible and rubbery (which is not what I'm after). After a few hours (overnight) it will harden into solid which has a slight flexibility, and some resilience which acts as a shock absorber for the glued bond.
As I mentioned, dripping CA glue onto a powder is nothing new. There are a number of powders, like ATH, baking soda, etc. which will cause the glue to set up quickly, but quickly is not what I want. The slow set time with this powder allows the thin CA time to soak in to deep gaps. Usually, the other powders will cause the glue to set up so fast that it doesn't have time to penetrate all the way into a deep gap filled with powder.
As described above, that method uses the thin, low viscosity CA glue. The thicker CA glue can also be used, but the method is different. Thicker CA glues will not soak into the acrylic powder, they have to be mixed with a stirring stick. This is not as convenient as using the thin CA but it gives a thicker mixture which has some advantages when gluing vertical surfaces. You can't sprinkle the acrylic powder onto a vertical surface, only a horizontal one. For those cases, mixing the thicker CA with the powder before applying it gives a thick enough glue blend that it allows you put it on vertical surfaces and make a vertical bond while still having the advantages of the thin CA (a slower setting time, large gap filling, and resilience).

This powder also has a mainstream application, namely as an ingredient in applying acrylic fingernail extensions by the ladies. I am not knowledgeable about all the methods of applying acrylic fingernails, but there is a wealth of information on the internet, both written articles and videos, just google the phrase "how to DIY acrylic nails" and you'll get all kinds of results. But, I would like to quote a short article which is an easy to understand technical description of why and how acrylic fingernails work, { https://shop.valentinobeautypure.com/blogs/news/how-to-use-acrylic-powder }:
"Acrylic powder is made from polymerized monomers. This may sound confusing and science-y but understanding it will give you a much clearer sense of what makes acrylic powder work the way it does. Acrylic powder contains the monomer methyl methacrylate. When you mix the acrylic powder with liquid, a process called suspension polymerization occurs. This process allows the monomers in acrylic powder to solidify and harden into a molded shape. Suspension polymerization is why, when you paint your nails with acrylic mixture, the mixture hardens and molds to the shape of your nails.
The acrylic mixture needs to dry and set before it will stay rigid. For this reason, after you paint acrylic nails, they need to sit for a few minutes before you add polish. Acrylic powder mixes with acrylic liquid to become moldable and spreadable, but time and air drying will make the mixture harden and form the shapes of nails, ready to be painted with whatever creative combination of colors you choose.
The combination of acrylic powder and liquid solidifies to make a perfect base that you can cover with any color nail polish you like! Feel free to experiment with creative color combinations and designs – you’re officially an acrylic nail artist!"

A final word which concerns using CA glue safely (especially the thin CA):
The standard safety precautions apply when using cyanoacrylate (CA), don't get it on your skin because it will glue skin to skin instantly. Also, if a few drops cure on a piece of skin it can cause a burn from the exotherm of the glue hardening quickly, the low viscosity type gets quite hot when setting. And, finally, use with adequate ventilation. When the cyanoacrylate sets up it gives off a fairly strong smell which is partially due to the exothermic heat of the fast cure. The powder is essentially harmless because it's a solid. The liquid version of Poly(methyl methacrylate) monomer is not harmless."
