Good product. Works really well. Easy to mix & no or low bubbles

This review will be edited time to time for updates! (UPDATE) Still a great silicone product for beginners! I made a second mold and made things in my first mold to compare them to their originals. I will be attaching another photo. Left is originals, right is copies from being in the mold(besides the cookies, I accidentally switched those.) I will upload a pic of my second mold as well! I am going to be switching to another molding product soon as I feel I want a tougher silicone but this was so fun to work with and such an inexpensive option for those who just want to make a few things on hand for back up pieces. My second mold's silicone was mixed more thoroughly than my first and cured much faster. The first mold took about 3 days to not be sticky because I didn't stir very well. make sure if you're using tape on the bottom when pouring and make sure you are taping very FLAT and fold the edges upward around your container because even with hot glue you can get leaks! 1st Impressions: LOVE! Very easy to work with, mixes easily and adding a little mica powder for some fun color was NO problem. I only had to wait 3-4 hours to take it out but I'd suggest you wait the entire 24. I think I may have ripped a teeny part on accident pulling it up out of impatience. I am attaching a photo of my mold. I needed extras of pieces I use for personal use. You can never have too many cabochons! I will come back and post pics of pieces made in the mold and update with how the mold did! Sorry the designs are so hard to see in the photo, the mica powder is pearlized. BY THE WAY: I had 1 TEENY bubble and I checked my piece to make sure it wasn't the issue but it may have been because it was slightly not flat in the area it bubbled. Nothing a quick glaze or dome can't fix. The silicone seems strong but I am still waiting to use it as it has only been 12 hours and I want to make sure I don't ruin it. If your mold is still sticky in ANY spots either you did not mix properly or you need to let it cure a LOT more.

Very nice! My first try with silicone. It was a learning curve and I made sure to watch a bunch of tutorials. The only thing that was disappointing was the “self degassing” part. Even slowing down the curing process didn’t help the bubbles too much even though I had mixed carefully. BUT, with a vacuum chamber this silicone turns very clear and it works well with UV resin. It has a great clarity for epoxy resin so you can monitor the progress of your work. It has a nice flexibility to help remove parts and it is sturdy when the part decides to fight back a bit.

Worked incredibly well. This is a platinum cure silicone and there are countless materials that will cause cure inhibition so be sure of the materials you are pouring this onto.

Easy to use, perfect molding material

I’ve used a few different platinum cure silicones, and this one worked just as good as the popular named brands for making a mold. I sculpt with sulfur free clay, and it cured with no issues. This silicone is pretty thin to start, so make sure you don’t have any tiny holes for it to seep out of, because it will. Because it’s so thin, the large air bubbles disappear rather quickly, though I did notice some micro bubbles in the final molds. It didn’t leave any imperfections in the mold, they were just visible. Im sure if you were less vigorous in mixing, they could be avoided. A trick I picked up along the way after a couple of molds failed to fully cure (with other brands) was to add a little dye to one of the parts before mixing. That way you can see when they are fully mixed. I would also recommend after pouring this and the silicone starts to set, leave it for a day at least. Don’t be tempted to Demold too quickly. That is the difference I have noticed with this brand and other less popular brands is that they tend to cure from the outside in and can seem fully cured to the initial touch but still be tacky against the clay I am molding. I let it cure for 48 hours (to be safe) and it demolds nicely and isn’t tacky. Hope this helps.

I wanted to replicate a mold that I already own. I wanted multiple copies of the same item so I can hopefully use them for candle making. I was definitely successful in creating a mold with this. The instructions were easy to follow. I filled my original mold with hot glue and made a bunch of copies of the cactus. I then built mold cavities. One out of legos from dollar tree and one from cookie cutters. I took contact paper and put it upside down and placed the mold walls on that and applied hot glue in order to hold it down and make sure there was no leakage. I measured on a scale part an and part b. There was a ton of bubbles and that made me really nervous! However in my finished product i barely saw any bubbles. I sat there and babysat this for at least a half hour blowing through a straw at any big bubbles I saw . I messed up on the bigger mold in my pics by not gluing down the items and instead trusting that dollar tree contact paper was strong enough to hold them down! A few of my cactuses floated to the surface and will now forever be entombed in silicone! I still got a few viable mold cavities. After the first half of the bottles were gone I decided to go ahead and try a second time. This time was a disaster! Once the bottle is half empty is is damn near impossible to get part B to come out of the bottle! The bottles are hard and don’t squeeze so you have to sit there waiting for it to slowly drip out! My scale turned off several times in the process which made things even more difficult! Part B should come in a tub or squeeze tube! Eventually I went into my garage and sawed off the top of the bottle so I could get a spatula in there and scrape it out! I even tried warming the bottles like you do with a baby bottle to get it to liquify more but that didn’t do much. It did help reduce some of the bubbles but it didn’t help part B move out of the bottle. I think possible storing the bottles upside down may help with getting the remaining few ounces out but I highly suggest they change the packaging somehow. Maybe put part b in a tub so that you can get it out easier. The more fussing you do with the stuff the more bubbles you introduce. The molds came out pretty good though and I even tried one with hot glue and it worked quite well. I would love to buy more and try more but not if they don’t somehow change the packaging. This is almost a waste because it’s so hard to get the remaining few ounces out of the bottle! UPDATE: I emailed let’s resin to ask them what I can do to get rid of the sticky residue that was left over on the top and bottom surface of the mold. At first they tried to insinuate I somehow didn’t measure and/or mix it properly and so I provided them with a video of me making my molds. Once they saw the video they then sent me an email telling me that it’s because I used “hot melt glue” as a master mold. They sent along part of their instructions where it does say that there could be potential curing issues with the “hot melt glue”. I don’t see how that is possible. The glue was fully cured and hardened for over 24 hours before I used it. In the instructions it says that the part that comes in contact with the “contaminate” may not cure properly. In my case, that is the ONLY part of the mold that actually cured properly! The mold functions properly. I’ve used it to cast already. It’s just the entire rest of the mold is tacky, causing hair and dust to stick to it. I would love one of their chemists to explain how cured hot glue will effect parts of the silicone mold that it didn’t even come in contact with such as the bottom, top and side surfaces of the mold! Sounds like a bunch of BS if you ask me and a company that just doesn’t want to take responsibility for perhaps a bad batch of silicone. I see other reviews here saying the same thing about the sticky residue and they did not use “hot melt glue” for their master mold. I mean right in the instructions that they sent to me and highlighted it says that the parts that come in contact with the substance that is supposedly a contaminate, is the part that wouldn’t cure right, so how is it that the rest of the mold is sticky? Makes no sense at all! They seem to be doing all they can to avoid having to replace items! I wasn’t even asking them for a replacement! I was just asking if there’s a way to get rid of the sticky residue! I emailed different resin company about an issue I had with their product and that time it was MY error and they replaced the bottles for me for free without me even asking! That’s a company that does right by their customers. This company is trying to avoid fault at all costs! Just be wary! If you ask questions they will do whatever they can to avoid blame and make it your fault, even if it doesn’t make sense!! As you can see in my photos, the casted part that actually came in contact with the cured “hot melt glue” came out perfectly fine. It is the entire rest of the mold that’s slightly tacky.
