Smooth-On Body Double Standard Set - 3 lbs Life Casting Platinum Silicone

It works great. I used it for extremely intricate mold and it worked awesome, every single small detail showed, and it’s very durable as well.

I purchased this Smooth-On set for a class project. I looked at a couple of other materials, including some alginate kits. I decided to go with this one, because I would be able to use the molds multiple times. Since this was my first time working with any sort of molding materials I wanted to be safe (probably too safe :D), so in addition to this set, I also purchased Hyper-Folic Release Additive and Body Double Release Cream (both Smooth-On products). I would have to say that this product is super easy to use and nearly impossible to screw up (adding the hyper-folic was also super simple). I only used the release cream once, since it leaves a waxy residue inside the mold, but it definitely works as well. I used the casting kit to make molds of hands, and releasing the mold from the model after the wait time took some patience. I did find that air-cans (the kind used to clean dust from computer keyboards) helps release the mold from the model (when used in short bursts) and it also helps release the positive mold from the negative mold. I definitely want to use this Smooth-On product for future projects I have in mind.

I have breast cancer and my friends helped me make a silicone cast of my OG chest for post-op art projects. This was the perfect product for it. Things to know: -I kept Parts A and B in a cold car during February in Massachusetts before use, personally I think this helped prolong the working time but it DEFINITELY made things more difficult to mix together- 1. Getting it out of the container is the most obnoxious part. Be prepared with a LONG, FLEXIBLE TOOL to get the goo out of the very bottom of the jars and scrape all the hard bits (white solids that are normal in both Part A and B) off the walls of the jar 2. Try to get as many of the lumps of hard stuff smooshed into the blue and pink goo BEFORE you combine them 3. Once you pour A and B into the same vessel, mix them very thoroughly but don’t rush or you’ll incorporate a ton of bubbles 4. Give the goo 60 seconds after mixing to get a bit more viscous if your body part is on a vertical plane, because if the skin is properly lubed up, THE GOO WILL SLIP if it’s still very thin. We had some issues initially while I was standing, but once the goo started thickening everything got much easier 5. It won’t make for a Pretty/Professional mold, but for a moment or two after the goo starts to gel, you can rip pieces of it off where there’s extra and use it to patch the exterior of your molding. It’s definitely an amateur move, but I AM an amateur, and it worked where we didn’t get things quite right initially 6. You will be able to feel when the mold has *really* set and begins to loosen and pull away from the skin. Be gentle, but know that as long as you’re properly lubricated, removing the mold is really very easy

I wasn't as easily able to tell when the blue + pink = purple was properly mixed compared with some of Smooth-Ons other color mixes. The flow was also thicker than I was expecting from previous experiences, and wouldn't flow down the narrow opening left along the sides of the box: 1/8 inch give or take. That led me to needing to change containers mid-pour which I was not prepared to do. Each product has its own character and I guess I prefer the other products I've used to this one, though those tend to be in the OO hardness. The softer RTVs usually have a thinner pour with lower viscosity. The resulting rubber is useful for detailed molds and really easy to peel off just about anything, including skin (woops, the transfer process made a mess).

This worked excellent for face casting. A longer working time is needed for larger surfaces.
