Review on Discover the Power of Ecoflex 00-30 Super Soft Platinum Silicone - Trial Unit by Linda Diaz

These are fantastic items! This is my first time using silicone to make molds, but Ecoflex-30 is so easy to use that I haven't had any issues with any of the molds. The silicone picked up every detail. I wasn't worried about bubbles (no vacuum or pressure was used), but to my surprise, most molds had very few, if any. The ones with bubbles were tiny and certainly didn't affect the quality of the mold in any way. Mixing was easy, but be sure to mix each original container before each use (this is noted in the instructions and on the containers). I used separate solo cups for each part (A+B) to measure, remix and then mix into one. The running time was 20 minutes (probably much more). I added some unused leftovers to the mold after about 45 minutes to 1 hour and there were no signs/issues in the final mold. Everything has grown together wonderfully. I'm impatient so I usually pulled out the molds after 4 hours (in a 65 degree Fahrenheit room) and they looked great. If I wasn't so impatient I would probably let it steep for a few more hours - some recommend up to 12 hours just to be on the safe side. Silicone is very elastic but very durable. I tested one that easily stretches 4X and it held up great. I've only had this stuff for about 2 months but the silicone blends are still good (have used some of these today). I'm not sure about the expiration dates, but the container warns that it has a short expiration date. I will definitely order more.
