Mixes together quite easily, and produces a flexible rubber that retains its shape when hardened. Both parts store separately quite well for a very long time, even after opening.

I've been following this company for quite a while and I've used some of their other products such as Body Double and the level of quality in the final molds are breathtaking. What drew me to using Mold Star 30 is not only it's easy mix ratio of 1:1 by volume (you can also mix by weight, which I did for my current project in the pictures), its low viscosity makes cast complex parts and 3d prints easy.When you get these, stir each jar VIGOROUSLY with SEPARATE mixing sticks (I used a silicone stir stick or a drill with a mixing paddle, just drill slowly)! Not using separate sticks will cause cross contamination and you'll ruin the material. I also love the colours which helps with knowing when it's mixed, you don't want streaks in it.Now, prepping your part for molding takes some planning on your part and having sulfur free plastilina clay is HIGHLY RECOMMENDED and IMPORTANT, especially on wood mold boxes. Once the two parts are mixed in a cup you have 45 minutes to pour it into the mold. And I like that because I'm not rushing to pour and 45 minutes is PLENTY of time to stir the material and ensure a proper mix. In that time, you check your dry mold, fix a few things, and even take time degassing the silicone (the vacuum pot is optional).After pouring, you'll have to wait 6 hours until it cures. I ended up sitting the mold outside overnight to cure and doing this on a hot summer night helps immensely, especially when using the cups to check on curing. It was 97°F when I poured the silicone and the leftover material was already fully cured 3 hours later! Wow.The only knock I have on this product is the pricing for a pint and the price kept fluctuating here on Amazon, but you get what you pay for. This stuff is high quality and having a few pints actually is a good thing too, so you'll actually use it.Overall, this is easy to use but the learning curve mainly hinges on how well you plan your design and your mold boxes. Also, doing this outdoors helps with odors depending on what region you're in, especially where the air is drier. Once the price falls back to normal, I'll be getting more of these.ADDENDUM: My masters are done in PLA. For those of you who are using resin printed models, make sure the resin is COMPLETELY UV CURED before using this.

Easy to use, great working time and strong upon curing. It's also well worth mentioning that the level of detail you can capture with this product is mind blowing. Work as advertised, and intended which is ideally what you want for any product at the end of the day.

The product was very good to work with. It took a fair amount of time to set, so there wasn’t an issue with it setting up before I was ready. The part “A” of the mixture it very thick, and part “B” isn’t. “A” will want to sink when “B” will sit on top. So mix, mix, mix! I mixed mine quite a lot and there was still some marbling in the bottom. It didn’t affect the set up. If you have very detailed items to cast, there will be lots of bubbles. Tap the sides gently and they’ll come up. If you are planning on making multiple part molds with this product, be sure to get the Mold release. I didn’t, and had to cut my pieces apart. It worked for what I was doing, but might not for all items.

This stuff is the best! I'm molding small resin pieces for jewelry and displays, and using the Crystal Clear resin in the molds.I realized after two molds, that my cure time was longer because my house was a little cold. But really. It ended up with no air bubbles in it even!! I'm in love.
