MR. RESINBlack Line New Formula! - Extra Yellow Resistance and Lower Odor! UV Resin for Jewelry & Keychain Making, Rock Painting and More. (1kg Resin)

Does not turn yellow and cures well

My sister and I make a variety of stuff, but our biggest seller is our crochet hooks. This new formula does take longer to cure, but it is stronger. The original is way more flexible. The image I have attached is with a gallon of water suspended from the 10mm hook we make. There is a noticeable difference in the flex. While the new formula does flex, and really it is unreasonable to expect 0 flex with ~8lbs suspended from it, the new formula bends less. Line for reference.There is less odor, too. Something that makes me really uneasy about using UV resins is the odor, and both the original and this new hybrid formula are great. The Hybrid has less odor overall.This resin will wrinkle a little bit, like the original. I have found this to be only noticeable if the product is 100% clear. Adding just about anything either stops the wrinkles, or distracts from them enough to not notice(which means they are small and not worthy or worrying over in colored pieces)This new formula does take around twice as long to cure as the original. We use a 4x5 grid 20W LED UV lamp in a reflective boxBubbles are a lot less, as this is indeed a much thinner resin than the original. Getting the bubbles out of the hook at the tip of our molds has always been a challenge, even with 2-part resins. This stuff is so thin it really has made our job so much more easy. It just naturally creeps into the cracks and spots you would need to tap to release air from.

I've experimented with various UV resins, and this one stands out for its exceptional quality. The quick cure time is a game-changer, allowing me to complete projects efficiently. The crystal-clear finish it delivers adds a professional touch to my creations. The low viscosity formula makes it a joy to work with, and the reliable results have made it my preferred choice for all my resin crafts. I can confidently say that Mr. Resin UV Resin has elevated my crafting experience. Highly recommended for both beginners and experienced artists!

I loved the old formula but it wasn't available. I covered 200 rocks and put them in the sun to dry. The top side was still sticky. With the old formula, both sides would be hard after about a short time depending on the sunshine. The sun was bright and hot today. I turned them over and an hour later, both sides are sticky. I will be looking for another brand

Viscosity is perfect, but it still gets a tacky finish after 6 minutes of curing under uv lamp. Washing with warm soapy water makes it a bit better but it's still a little tacky and it gets scratched easilyUpdate: after shaking the bottle before use, the tacky feel is mostly gone. It still gets scratched pretty easily
