  • 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

  • Worked in spite of me...
Size: 140OZ
I am a beginner at mold making. This product is forgiving and worked in spite of my mistakes. The company responded quickly to my order, I received to product quickly and the price is right for my budget. My molds work well and the product performed as advertised. I will purchase from Let's Resin again. ... show more

  • Nice price and works
Size: 140OZ
I started trying to make some resin dice with these and they have worked great. I've tried using a more expensive mold to compare but I don't really see a difference in performance from what I'm seeing. So I'll be working with these more since they're a LOT cheaper.

  • Great quality
Size: 64OZ
First time using this and making mold. It also has great instructions about making the mold. The quality feels great and and the rubber is super sturdy after cured. I forgot that Part of my item that I wanted to mold was air dry clay and I mold it without putting a protection coat on the air-dry clay, so it sorta infused with the mold liquid and didn't cured all the way so it was sticky but the mold still capture the details on the clay which I'm impress even though it didn't cured completely. But the part that was resins, cured completely and very sturdy mold. I love it! I'll repurchase again! Thankyou for inventing great quality stuff! ... show more

  • Never completely cures
Size: 64OZ
I’ve been really trying to give this resin the best shot because I really like their UV Resin. I make fishing lures and I’ve been trying to cast a master so that I can make resin baits. But every time I’ve tried to make a mold of a lure the Silicone never cures on the surfaces touching the lure. I’ve tried letting it cure inside my house where it’s warm, in the garage where it’s now even hotter about 80-90° F but every time it’s fails in the same way. I thought maybe there was too much moisture in the clay I was using to make the mold so I let the clay completely dry and I had the same results. I made sure I thoroughly mixed the silicon and used an accurate scale down to .05 of weight 1:1 ratio for mixing and I just can’t figure it out. Maybe I just have a bad batch. Not sure. Would be willing to try again if company would send me another batch to try but won’t be buying with my own money again so far a complete waste of $50. ... show more
