Review on Premium Clear UV Resin Craft Kit for DIY Jewelry Making and Craft Decoration, Solar Cure Sunlight Activated Ultraviolet Resin with Mold and Starter Kit (3.3oz) by Michelle Langley

I mainly use UV resin to make rings. Then put it in my curing chamber. I do different tests: 2 minutes, 3 minutes, 5 minutes, 7 minutes, 10 minutes and 20 minutes. However, this may seem like overkill; these tests will tell you a few things; With your current methods, how quickly does it harden, yellow, shrink, crack? Won't heal and turn yellow? will he smell You should build on all of this when testing, NOT when developing a product for a customer. I myself used my 405nm curing chamber which is designed for SLA UV resin and NOT this type. The UV resin took about 5 minutes but I set it to 10 minutes to be safe. The surface was a bit sticky due to the wrong wavelength, but sanded it down with no problem. This bottle is also small enough that you can slip it in your bag and let it warm up a bit while you get your workspace ready. This makes it easier for bubbles to form. It's good to buy smaller bottles. However, you may WANT to save money by purchasing a larger bottle; If you don't use it before it expires, it's just a waste and will end up costing you more money. My only complaint about it is that I wish it was a bottle and not a tube. When you put it in, you need to put a lid on it to keep it from leaking. I like putting the bottle down, doing something, and then picking up the bottle again. I can't do that with a pipe. BUT it also means the tube and putting on the cap means I can't knock it over or spill it. The smell is no different than other UV resins I've used. I didn't notice any shrinking, cracking, or yellowing in my testing. Overall I am happy with this product and will definitely buy it again.
