  • Perfect!
Size: 140OZ
Mixes well, mold is firm and pliable enough to hold its shape and then release the item easily

  • Good silicone for mold making and miscellaneous projects
Size: 140OZ
I bought this silicone to make lava rock negatives (stamps) for some concrete projects I'm planning on doing around my house. This product seems pretty on par as far as price vs. volume compared to other brands here on Amazon. I haven't tried any of them so I can't compare, but this product seems to harden (to the touch) quicker than another company's silicone that I was buying elsewhere. That, I do like because I'm very impatient. It can theoretically be de-molded in about 30 minutes in aprox. 80 degree ambient temps. Fully cured in 24 hrs. I would assume. Detail is good. I like that it's clear. Some companies have weird colors like mint green, salmon pink, etc... I mean, there's nothing wrong with those colors per se, but I think the clear is a good neutral look. Mixing directions are self explanatory. It would be smart to use some disposable rubber gloves because silicone in it's unhardened state will stick to anything. Use acetone for cleanup. In conclusion, this product surpassed my expectations as far as performance and it is priced comparably vs. the competition.Couldn't have asked for much more. ... show more

  • really good mold silicon
Size: 140OZ
I dont usually diviate from my favorite silicone but i needed some now and this looked good so I( gave it a shot. It's easy to use and super sturdy once cured. However there were no instructions with the bottle. None written o nthe bottles or anything. I had to look the info up and hope for the best. I highly recommend adding an instructions sheet in shipping cuz begeinners aren't going to think to look up info online sometimes. ... show more

  • Worked perfectly with just a little patience
Size: 140OZ
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. ... show more

  • Not curing ever even if I leave in the mixing container.
Size: 140OZ
I got this because I tried the blue version [Kit 30A] they have and it worked fantastic. However this one no matter how I prep it. Vacuum out the air. Let it sit. Mix for 5 to 10 mins. Use Scale to make it sure exact measurements it refuses to Cure. I have tried heat and everything. I listened to all precautions and nothing works. I used the same system as with the 30 kit. But no go. I have let sit for 5 days no go. I have had to clean all my items I am trying to make mold with and it does not work. I am disappointed in this and at a loss of $60 for something that does not work. ... show more

  • Fantastic silicone, so easy!!
Size: 140OZ
This was my first time making silicone molds. I was going to do a small one and test it out, but then I decided I would just go all in, colors and all. Other than the molds taking alot more silicone than I thought they would, everything was perfect. All of these molds took both the 4.4lb bottles. It was a ton of silicone, although I did 8 small, 9 medium/large, 1 large, and 3 really large molds! The mica mixed in easily and colors are beautiful! The molds are perfect and very sturdy. I'm so happy with the silicone and these molds. Will definitely be repurchasing! ... show more

  • Bad batch maybe?
Size: 352OZ
I love let Resin products. This is the first time having issues with any. Says 4hr cure time, yet I have made 8 molds at room temperature- cure time ranged 8-12 hours. The thickness at max 1in, depth 1-3 in. unfortunately I bought the largest container - 11 lbs. Really hinders time management. End product is great but 2-3x time to cure. Not happy about it. Would love replacement if offered. ... show more
