ETI Environmental Technology 128-Ounce with 1/2-Ounce Catalyst Casting' Craft Polyester Casting Resin, Clear

This product was purchased for me to make jewelry with my daughter using molds. I mainly used silicone molds and while they do sell resin release spray, I didn't use it and did not have any issue with resin sticking to the silicone molds. It is very important that you mix the two chemicals exactly as directed, otherwise you will have issues with the product setting up and it will end up being softer than it should. I used childs medicine cups to measure them and I used wooden popsicle sticks to mix them together, get a box of those, you will go through a lot of them! Toothpicks are handy for positioning/moving things you might put in the molds like beads,coins, tiny shells, sequins, basically anything that would fit. The product dries clear and shows what you have put it very well. It takes about 24 hours to fully set depending on how deep your mold is. This product works very well, price is competitive vs. going to a hobby store.

This is the first resin I ever bought, and attempted jewelry with. Pics: first is the box. The second is showing the resin preserving a picture in a necklace jewelry piece (popsicle sticks to cover faces).Note that I sealed the picture in mod podge first. And the third is showing some jewelry I made with it. Being a newbie to it all, I found that the resin was a little overwhelming to make at first. Scared to mess it up by it being too hot, too cold, or not a perfect 1:1 ratio, but now that I’ve been using it for a week it’s a lot easier. First time use went well. Followed the directions and my resin jewelry came out good! I love how they turned out. I definitely need to work on my skills but I think this resin works well and it’s just me needing to learn tricks. When I got the resin to the right temperature (about 73-75 f), it worked well and had a clear and hard cure at about 18 hours. My first attempt it took 3 days for a hard cure. And yes they were the same jewelry pieces. So I would say I have improved and it’s just a matter of skill and following directions. Would definitely buy again. If you’re wanting to get your foot into the door with resin, I highly suggest this!

My use was not typical as I wanted a void filling resin for an Eastern Red Cedar bench I was making. The problem was a void in the wood that I did not want to putty in or otherwise cover over, but wanted to filled so that its natural internal contours could be retained, even though it would be on the underside of the bench. I cleaned out the void so that there was no dust or other material to fall out, and had to use tape to support an extended fragment from the main piece that went over the void space. For this I would use cheap, plastic shot glasses to mix the resin as they can be easily disposed of. The process was a multicast procedure which took a few batches so that the exothermic reaction wouldn't cause natural wood oils to come out of the wood. The first pour was just a base one to get into the hidden void spaces and make sure that nothing came out to the other side, which is always a worry with a wood like this. I kept the piece covered so nothing would get on the surface and then the second day poured another batch in, following the first day's procedure. A total of 4 pours were needed to get the resin to near the tape supported piece and the tape was removed for the final pour to allow the wood to rest naturally against the prior day's pour. Pour 5 started the final covering procedure and came around that wood piece to support it up to its sides. I was willing to let the hardened resin be a bit concave which happened as part of the normal shrinkage in casting. With good adherence to the sides and internal void spaces that was the only way it could shrink. Now the bench has that as an extra feature which took some time, but seemed like a much better idea than just filling it in flat with putty or colored epoxy. PROs - Easy to work with - Fills in void spaces - Relatively fast set-up for multi-pour situations CONs - Exothermic, which means thinking ahead on the amount to cast at a given time - Shrinks as it cools - Time consuming for larger pieces For me this was a great solution as an alternative that my normal methods wouldn't address.

I ordered this to try resin casting jewelry, and it worked great for my needs. The mix ratio is a bit forgiving (within reason), and the epoxy was easy to use and mix. A few bubbles formed in the epoxy during mixing, but when casting I found almost all of them could be removed by dividing a pour into several smaller pours and grazing the top of the casting surface with a lit lighter to pop bubbles before continuing casting. I would say there is enough resin here for at bare minimum half a dozen cast pendant-sized pieces of jewelry, and I probably made 20 pieces total. I did find that after a few weeks of use/storage the epoxy yellowed. The yellowing wasn't complete, but was definitely noticeable compared to previously cast pieces. The yellowing process occurred very quickly- I could see an obvious yellowing in cast pieces when compared to pieces made the previous day. Overall I would say this is a great product if you only need to cast small pieces and/or want to see if epoxy casting is for you.

good product!!!
