ECOFLEX 00-35 Fast Platinum Cure Silicone Rubber Compound, 2 Lbs

This is great stuff, but you -really- need to know that its FAST FAST FAST setting! Get everything ready to go, mix, and pour that sucker! Don't dawdle or it will turn to rubber in the cup! The end result is super soft and makes great suction cups for complex surfaces. Definitely buy some silicone mold release: Ease Release 200 is what I used and it worked perfectly! Note: you need a mold release that is specifically for releasing silicone rubber from a mold. The usual stuff is mostly for keeping things from sticking TO a rubber mold.

This stuff sets FAST, and that's a great thing for some body molds. You have time to stir for like 1 minute before putting it on and it's fully cured to the touch in under 5 minutes. No waiting around with sticky half-cured silicone on your skin. I would definitely not use this for anything deep with fine detail though, because it's pretty viscous and sets so fast there's little hope of popping air pockets unless you're extremely skilled. I'll be using this for every single body application I ever have though. It's just such a huge quality of life improvement.

They claim pot life is 2.5 minutes; in my experience, it was less than 90 seconds, including the mixing. So, you have to be extremely quick. I started mixing for 45 seconds and then poured the rest of the time, which was very hard. But if you can manage, this is a godsend. It cures in about 4 minutes. No more waiting hours each time.

In short: Great for quick turnaround, takes pigments incredibly well, good strength, overall fantastic silicone depending on your needs or project. A little nighttime reading breakdown: Bought this specifically for its short pot life and for casting silicone in silicone. Anyone new to making a silicone casting (not a mold) ensure you use a mold release or a thin coat of Vaseline! Otherwise the silicone will bond to your mold and that’s a wrap. For aerosol release I prefer either Stoner Brand (if painting your castings Stoner has a great product that does not leave that annoying residue that paint hardly adheres to… or Mann Ease Release 200 Pot life: I believe it’s 2-2.5 minutes depending on your current climate. I’m able to squeeze an extra minute or two out of this by putting both A and B side in an ice bath for for 20-30 minutes. When you’re using a pressure pot this is incredibly helpful as that 15-20 seconds it takes to tighten down the lid and hit it with pressure is everything. Pigmenting: It takes pigments incredibly well: Mica and SilkPig from Smooth-On are the two I used. Zero issues with curing or cure inhibition.

Ecoflex 00-35 i definitely a fast setting silicone. It is also not as soft as I thought it would be. Overall, I liked how easy it was to use, after I got over the fear of working with it. I would buy again and recommend as well.

Excellent, that's what I need it. 🙏

I had high hopes for Smooth-On Fast 00-35, but what I received was either past its shelf life or completely defective. Even before mixing, I noticed clumps in both Part A and Part B. I weighed both parts, but within 30 seconds of mixing, it started setting up—way too fast to work with. By the time I attempted to pour, it was already half-solid in the mixing bucket. Even after an hour, it still hasn’t fully cured and remains a useless half-solid, half-liquid mess. This was a complete waste of time and money. Very disappointing.

I just getting into Silicone, after having done latex for many, many years. I wanted something I could start small on, and not have to create large expensive molds for. This stuff is perfect, and has worked out great! Was able to cast several small projects with rubber molds, and the finished silicone prosthetic is awesome. Used the Smooth-on colors, and some flocking powders, and the end result is everything I had hoped for. I only wish this trial kit was larger... will have to buy more.
