UV Resin Kit with Light, 60g UV Glue for Bonding & Curing in Seconds

I felt the need to write my own review of this UV resin to offset the (in my opinion unreasonable) negative reviews. I just bought my second bottle, as the one I've been using for over two years is finally starting to get low, and it's been so wonderful that I don't want to risk running out. Below, I'd like to address a few key points: 1. Usefulness. The photo I attached is of a small (8" tall), clear, light-up Christmas tree decoration, the top 1/2" of which had broken off and gotten lost. I was able to reconstruct it easily by dabbing on a bit of resin at a time and curing it mid-drip to make new branch-tips. You'd never know it had broken. That said, the resin doesn't stick super hard to most things other than itself, so making sure to sand surfaces prior to application--or even better, applying it in such a way that it can flow around part of what you're repairing in order to lock onto it mechanically--is very important. 2. Shelf life. As I said, I've been working with the same open bottle for two years now, and it works just as well as ever. The tree light in the photo was repaired last week, and the resin cured hard and clear like normal. 3. Yellowing. I have never, ever, had issues with yellowing or color distortion with this resin. In contrast, the "clear" UV resin I bought to use with my 3D printer yellows significantly with additional UV exposure, to the point of turning amber after several minutes of post-curing. The same amount of UV exposure makes no perceptible difference in the color of this resin (the one I'm reviewing). 4. Curing. Okay, I think I know why some people are having trouble here. I have a 405 nanometer UV lamp for post-curing 3D printed resin things, and I've found that this resin never cures fully with that light (the surface stays tacky and takes fingerprints). Luckily, I have a 395 nanometer UV flashlight intended for spotting pet urine, and it cures this resin fully and flawlessly. I would never have thought that the exact UV wavelength would make such a difference, but it seems it does. So if you're having trouble getting this resin to cure with a UV light, double check the wavelength. If it's 405nm, try 395nm instead, and see if that helps. (Edit: I found the flashlight's original packaging, and it claims it's "390-410nm", so maybe the broad spectrum makes a difference? Also, I noticed my resin wasn't fully curing with that flashlight anymore, and it turned out that I needed to change the batteries. Unfortunately, the light will continue emitting a purple glow long past the point where it's no longer strong enough to fully cure the resin, so it's something you have to stay cognizant of as you use it.) 5. Bottle size. Really?? Yes, the resin sometimes comes in a bottle of a slightly different size. Sometimes business have to order their containers from multiple different manufacturers depending on availability, and therefore the exact shape and size can vary. That doesn't mean they're trying to cheat you. Shake the wet cat food out of your skull. Did you get the volume of resin advertised? Then there's no problem. smh 6. Storing the container. The bottle is made of opaque black plastic that, as far as I can tell, lets in no light whatsoever. I'll occasionally shine a UV light directly at the bottle to cure any resin drips that have accumulated on the outside to make them easy to clean off, and I've never had it affect the inner contents in any perceptible way. So I guess what I'm saying is that I wouldn't worry about the bottle starting to harden prematurely from incidental light exposure. I'd worry more about extreme temperature fluctuations. Update: I finally ran out of my first bottle and opened the new one. First, I noticed that the bottle was slightly shorter and wider than the previous one, but seems to be of the same volume. The next thing I noticed was a strong herbal smell (not a chemical smell, oddly enough), like something you might whiff at a Traditional Chinese Medicine shop. I don't find it at all off-putting myself, but some might. Beyond that, I can't tell a functional difference between this resin and that of my previous order.

So I've tried several brands of UV cure resin, and by far this is my favorite. Even tho it's a little finicky to cure, if the UV light isn't strong enough it won't cure all the way and will be tacky to the touch (tho that can be remedied by just leaving it in the sun for a day), but the results are very worth it since the finish product has a nice solid feel similar to glass (which also means it can be sharp so be careful with sharp looking edges), not to mention it's extremely clear and shiny. Plus while it does have a strong smell, it smells like pine sap so it's not unpleasant unless you don't like the smell of pine. Another thing to keep in mind is that this stuff gives off significantly more heat than any other resin, UV or otherwise, when it's curing so be careful of when you put in it or put it on

I have used this glue a couple of times to glue some wires down on an R. C vehicle that I drive regularly and it's been holding perfectly for approximately the last month or so. I would definitely recommend it for small projects.

Works as advertised. The cured resin still smells and is oily, leaving the smelly residue on fingers. Not for external bonding.

The negatives I keep hearing about it remaining tacky I can attribute in part to people using low powered UV lamps or flashlights. I used a UV flashlight to test it and while it did cure it still felt a bit tacky. I left the flashlight on it for a good 5 mins and it felt less tacky but not tack free. I got a 36W UV lamp and put it in there for a total of 4 mins...the surface was crystal clear, beautifully smooth and completely tack free. I don't know if it made any difference but I also treated it like I would a two part resin where I put the bottle in a container of hot ( not scalding) tap water for about 20 mins to warm it up so it would flow more freely and any bubbles would rise out a little easier. . Winter here is pretty chilly so even if the ambient temperature feels OK it's best to make sure your resin is decently warm. Can't attest to the bottle size if it's in fact a full 120g since I have nothing to compare it to but so far I like this resin and just wish they sold bigger sizes. I will be buying again. I have had a decent amount of experience with two part resins. When I started learning about UV resins I wanted to try it in order to achieve some effects that was very difficult or not possible with regular two part 24 hour resins or even a quick cure will not achieve. The resin does have a smell but it is not overpowering. However, even so wear a respirator and gloves because many people who enjoyed this hobby had to quit because of developing allergies from repeated contact with the resin on their skin of breathing fumes. I don't use this for large projects, mostly to cover up certain objects like stickers or paper because since it can be dried so quickly there is little risk to it saturating the item and deforming it. I tested it on a vinyl sticker I was encapsulating in resin from an inkjet printer and did not coat it or seal it beforehand, the colors did not run or smear. I did leave the sticker to dry overnight in a warm place to make sure it was completely dry. Did some quick experiments of covering inkjet printed paper designed ( small ones ) and there was no running or smearing either. I would still prefer to seal it with Krylon UV Resistant Sealer or Modge Podge but this seems to work great if I need to get something done quickly. As far as appearance it is crystal clear with virtually no bubbles. Any that do show up can be fish out with a needle or popped with a lighter if they are close to the surface like regular resin. Even better is to leave it in a sealed contained ( for the fumes ) to let all the bubbles rise up to make it perfectly bubble free.

Sigh. I had such high hopes for this product. A one-step resin that cures in sunlight? A crafter's dream! However, in this instance reality did not meet expectations in any way. First of all, accessing the resin is problematic. For something like this, where time is of the essence and exposing the product to light starts the curing process, there should be a spout of some kind! There isn't even a flip-cap thing like on shampoo bottles; it's just a screw-on lid. Luckily I had some pipettes laying around, which I was able to use, but those aren't ideal either, since they're almost impossible to use without getting some bubbles. But for a one-step process, I could've lived with that. But the resin itself? Even worse. I tested this with a mold smaller than a quarter and maybe 1/4" deep, and after 30 minutes... it hadn't set at all. So I figured, okay, whatever, I'll just leave it in the sun for a while longer. I ended up leaving it in full sun for an entire day - at least 12 hours - and it's STILL tacky, with the same chemical smell as the uncured product. At this point I'm pretty sure I could throw my test pendant into a sun flare and it would come back just as sticky. What's worse, once I realized the stuff was never gonna cure, I had to un-mold it, which left a film of resin on the bottom of my mold that I have no way of removing. So I guess I'm down one mold, unless maybe I add a thin layer of resin, let it sit through a week of full, sunlit days, and hope the two batches cure together enough for me to pop them out in one chunk. There's probably a lesson about shortcuts in here somewhere, but I'm too grumpy right now to find it.

I love this UV glue. I use it almost specifically for model car building, and mostly for securing clear windows, and have no problems at all with this. It holds tight, does not fog the clear glass, and dries super fast. The only I have is that slide button is a little tight. I would have like to have seen a push button on/off switch, so it can be accessed/used easier, but that's just my unhumble opinion. The tip can be adjusted for the amount you need, so start with a super small cut first at the tip, and if you don't get enough flow then, go just slightly larger on an angle cut. Highly recommend, and will be featured in the magazine soon.

I’ve no conflict of interest and this review is solely to help public. I bought a glass table where the metal 'boss' had detached from the glass (the resin bond is very strong for vertical forces but can’t hold with horizontal sheer stress). Because it’s a heavy tempered glass slab on three wooden legs, the interface needs to be incredibly strong. After several failed attempts with other glues, this UV kit did the job. Tips for success: 1. Scrape off every bit of the old factory glue first, make sure both surfaces are very clean and use 100% alcohol and razor blade if needed (with extreme caution and special gloves to avoid cuts). 2. Use a liberal amount of resin (thick consistency somewhere between honey and water) in center to ensure no air bubbles, avoid too little or too much of it. 3. Hold it tight while using the UV light, drying time is decent and if you avoid bubbles then appearance would be great. It cured clear and is holding the full weight of the glass perfectly, nice appearance and good value for money. Saved me from throwing away a nice table! I can afford but avoid waste and carbon footprint if it can be avoided. I am a novice so some bubbles are there in photo attached. Finally, please do this on your own risk with protective glass, gloves and maybe mask as odor is high. Better to do this project in open air or open garage avoid direct sunlight till you cure it.

Não é muito bom

This little kit worked amazing to seal a crack in glass. Very easy to use and would highly recommend it.

A great product to keep at home for many things that might need a fix with a clear resin. This resin cures fast with little odour and hardens solid and clear.. Any household should have this in the drawer with things like elastic bands and Elmer's glue and pins. Excellent product.

Resin doesn't fully cure in the 5-10s as advertised. It's left a bit soft (a bit more hard than a hard candy)

Works exactly as intended and exactly like the ones in the tiktok videos. I used this to make repairs on my cars valve cover. The flashlight is pretty cheap but to be expected at that price. I used my own higher quality flashlight. Be careful when using this in sunlight as the liquid at the top of the nozzle will begin to harden in sunlight
