Ecoflex 00-20 - Super-Soft, Addition Cure Silicone Rubber - Gallon Unit

I purchased this to make a practice hand for nails. This hardiness is too soft and not good for that purpose. The fingers are too flimsy and the surface is sticky. So if you're like me and want to make your own practice hand, go up to 25 or 30. Aside from that, the product itself worked fine! As soon as it was delivered, I brought it in the house and made sure there was no spills and that it did not cure on its own. After analyzing it, I took it to the coldest part of my house, the basement. I left it there until I was ready to use it. About 2 to 3 days later. I did used the pigments to color it and it took to the pigments well. ( I colored part A and B separately) I had plenty of time to incorporate the two parts together. I poured it into my mold let it set for 6 hours. When I pulled it out there were lots of air bubble, but I will say that i was my fault. This is was my first time working with liquid silicone rubber. I should've poured it from a higher distance and slower. It is a good product and I would buy from this brand again. I hope they get more products on PRIME.

The media could not be loaded. I hate how most silicone reviews don't show videos of the strength or flexibility of the silicone. So here's a quick video. I don't have a degassing machine and it works great without having to do that imo. Really great for wax that isn't super strong like soy and coconut. All other silicone that I've tried is just too stiff to get the wax out of the mold without the wax melt/candle breaking in half. This stuff is a game changer. Works well for undercuts. Definitely repurchasing.

Easy to use

The media could not be loaded. I saw an earlier review cautioning against using this siliconewith resin. I'm glad I didn't see it first before nearly completing my project, otherwise I might have been scared away from a successful result.It is very soft though and you do want to make sure the mold you make is thick enough to take on the demolding process without tearing. Any thin areas will be vulnerable to tears I also used the silicone glue offered by the same company as an added support in areas.That said, I wanted something soft and stretchy for making quartz cluster molds and potential Christmas light molds for next year. Since I am using UV resin, the silicone had to be translucent enough for the uv light to shine through. This turned out perhaps softer than intended, so I might try more variations to see what ecoflex has to offer.End result has a slight tack, very stretchy. Translucent. Captures details well and demolds with ease. To make the molds, it is better pouring in small steps to reduce air bubbles. I would pour a small amount at a time and let it cure before adding more silicone. These photo examples are test and practice pieces for now, but I am pleased with the molding.I rated it 4 stars mostly as a cautionary measure, because there is a bit of a learning curb and it takes a bit of work to turn out, but it is worth it. Also make sure to mix it well. It can be hard to tell if you opt not to color one of the parts before mixing.

Pros: This material is easy to mix and easy to use. Very soft and flesh-like.Cons: the stretch and tear resistance seams to be a bit less than advertised. It tends to start to rip in a weak point. Once it starts to rip it's game over the tear just keeps going unless you cut a strait line ahead of the tear.

I do a lot of molds and use various Smooth-on products. All of them are easy to measure, mix and pour with great results. The mixes leave a lot of room for error which is a relief for beginners and experts alike.

First try I just went for it like I would paint, "in a hurry" stirring the 2 compounds to gather, it worked but I noticed the caps on the bottles say to stir each compound before mixing, did the the second time and wow, it came out a lot more clear, more smooth and less bubbles, overall about 70% better quality the the first try. Hope this helps someone who got somewhat less then good first try experiences out there.

I've purchased several boxes of this and other hardness silicones. The 00-20 is soft, stretchy, and if properly mixed, leaves no tacky surface. Very similar in texture to toe caps.All in all, an excellent product, but I have to warn prospective buyers confirming other reviews of this product: you won't always get what you order! As per my attached image, you can clearly see its Dragon Skin 10, but the barcode sticker is 00-20. Not the same product or shore hardness. I'll give it a try but I doubt it's going to work for my purposes. At almost $50 bucks a box and with a limited shelf life, this isn't an easily forgiven mistake.Since others have reported the same issue, I'm docking 2 stars. Otherwise this would be a 5 star product. If you get what you pay for, it'll work great.
