Let's Resin sold by Amazon is a great product. Low Viscosity, self degrading and easy to demold. I use it in my molds after spraying them with mold release and make rubbery dragons and lizards with them

This is great quality silicone. Very sturdy. I’ve made 2 molds and poured them each 3 times and the results were perfect. No issues with bubbles after degassing the silicone for 5 minutes, and it cured perfectly and the molds were ready to be poured into after 2 hours. I stirred a bit of mica powder into the silicone with no negative effects. I was duplicating smooth glass pieces and the cured resin was exactly like the finish on the glass. My room temp while mixing the silicone was approximately 75 degrees Fahrenheit which is close to the 77 degree max temp recommended in the directions but I had no issues with diminished working time. I’m very pleased with this product and would recommend it.

I mixed and poured this in my basement which was at about 60 degrees Fahrenheit and probably relatively high humidity. An hour later it was still liquid and had not cured. I set my oven to dehydrate which is a 170 degrees Fahrenheit. Once the oven warmed up, I turned the oven off and placed the still liquid mold into the oven for several hours. There it hardened up and cured nicely.

Easy to mix, captured great detail. Holds together well, was easy to cut and unmold without tearing. Love the translucency. It arrived fast and was fresh. I usually use Oomoo but I've had issues with it arriving expired, so I took a chance with this silicone and am very happy with it. Also liked that it comes in small batches.

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 got this a number of years back. My first set of projects ended up having a tacky finish. They worked fine but i wasn't loving the stickiness so I covered the top with acetate to protect my surfaces. I moved house, and wanted to use the last of the silicone before it hardened. I used a more accurate balance. After demolding my pieces there was no tackiness. My new home gets hot upstairs where I store my craft supplies. I decided to check the pieces that I had made before and there was no tackiness. The take home message for me is: 1. Use an accurate balance. 2. Heat helps set finished pieces.
