Miraclekoo UV Resin Clear Hard Transparent UV Curing Epoxy Resin Ultraviolet Curing Solar Cure Resin Sunlight Activated Resin for Resin Mold, Jewelry Making Casting & Coating,100g

I love this UV resin!!I didn't used to want to bother with resin because of the smell and mixing and making a mess, I have to wear gloves, I have to wait for it to dry, I am an impatient crafter, I simply cannot!Then I came across this UV resin while watching videos about pin doming. I used to use mod podge dimensional magic but it took FOREVER to dry and makes the ink on my pins bleed.The Miraclekoo UV resin cures hard in 3 mins (for my small 1.5" pins)! Probably less but that's what I set my timer for. Bubbles are so much easier to pop, just wave a flame over it real quick with a lighter and poof! No more bubbles! It doesn't make my ink bleed and I can just use my dog pee detector (lol!) to cure it. Why not? It's a 12 LED 395nm UV flashlight and it works well with this resin. I built a little curing box for it so the UV light is contained and not exposed. I mostly use this for small things: pins, magnets, keychains, jewelry, purse hooks, some embellishments, nothing bigger than 5" so my little flashlight oven works pretty well. Also doesn't smell bad, some hint of chemical smell but you have to have your project real close to your face to be able to smell the faint chemical smell while wet.

This resin was perfect for the personalized lapel pins I was making. It was easy to work with and I didn’t have any issue with the resin hardening in the sun but I do live in Florida where the UV index is between 7-9 during the day.

I generally like this resin but after 4 min under my UV nail lamp the surface was very sticky and slimyAfter an additional 6 min (ie 10 min total) it was sufficiently cured. Ive had this problem with many of the UV resins I find on amazon, when they say 2-4 min its usually 10+ min. Maybe my light isnt strong enough for this resin but my lamp works on sophie and toffee UV resin. Larger castings are a bit tricky, i cured my castings in about 2 mm layers. The resin colors nicely with liquid resin dyes but doesnt do well with mica powders cuz the light cant penetrate through. Hope this helps :)

Since this is a UV resin you need a UV light, I see some people not being able to cure their resin and are using huge watts but I only ever needed a small uv flash light you can find on amazon. That being said there is some stuff that can prevent curing of the resin like:too much pigment. putting too much powder or ink or darker colored inks can prevent resin from curing all the way through. Make sure your colors are translucent or do curing in sections for more opaque color!If your mold or setting is not clear. An opaque colored mold can further inhibit curing, a clear resin piece should be okay for curing in a non-clear mold but clear molds help a ton for better curing.I also cure my pieces with the UV flash light and then leave them in the mold for a second. The piece is typically hot after curing, this is normal, so I like to let it cool for a sec and if I am ever worried about a complete cure I de-mold the piece and leave on my window sill for awhile before touching it too much. This helps a lot with open bezel pieces.Dullness I find is common in UV pieces, ESPECIALLY if the mold you are using is NOT shiny. Shiny molds produce a shine in the resin, non shiny molds make your pieces dull. I would either just dome the piece with more resin or polish it with resin polish, brings the shine right back!If you want to do darker colors and opaque glitters etc I suggest getting two part epoxy resin, its much easier but takes a little more time.and SAFETY. No matter the resin YOU NEED TO USE A MASK. Smoking and smell coming from the resin while curing it is normal, please wear a mask to and work in a well ventilated area to protect yourself. Resin is a chemical. GLOVES are also essential, please work with resin safely!

It came safely, had no spills when it was delivered to me. I did love how easy the bottle was to squeeze and the resin flowed nicely. Unfortunately when curing it did not cure leveled, if anything sometimes it created almost like a bubble or hill of resin. Also it took maybe 4 mins to cure with my uv led light. And even then it was very sticky, so i would try curing for longer. The smell is there too. It’s not crazy strong but it was noticeable when i was working with it so i would definitely recommend wearing a mask. Also it hated alcohol ink. This is my first try with uh resin so I’m not sure if they all don’t work well with alcohol ink or if this specific brand you’re not supposed to put alcohol ink but it would bleed so much and make a colorful sticky mess. Overall it’s really hit or miss.
