I’ve loved both silicones that I’ve purchased from this brand. Easy to mix, long working time(40-50 mins), and fully cures in just a few hours. What’s not to love? I mixed the silicone to make a mold for resin pouring and roughly 6 hours later I was pouring the resin in that mold. The final product is strong, much more durable than other silicones Ive purchased and the amount you get is a lot more usable than the brands selling only 500ml or 600ml.

30A is a measure of hardness/stiffness when cured

This stuff worked great; I'm using it to make molds of small architectural monuments, and it's working really well! I have no baseline for comparison to similar products, but I likely will by tomorrow. The worst thing about it is that it cures pretty hard, so it's very stiff, which can make it kind of difficult to get cast objects out of it; specifically, if you're using modeling clay, you kind of have to destroy the model to get it out of the mold. The best thing about it though, is also that it cures pretty hard, which makes it reusable with minimal deformation. I've made 5 molds so far, and I've used all of them at least twice; one I've used 3 times, and the objects are coming out pretty much identical, with a couple exceptions which I can chalk up to external factors (One mold is for an impractically delicate obelisk-shaped object about 4.5 inches long and 0.25 inches square, it's had issues with the tip breaking off during removal, and the other exception is I tried to experiment with adding acrylic to my plaster, but that had weird results and I now think it's because what I added wasn't actually acrylic paint, it was acrylic finisher/sealer... oops.) So anyway... If you want to make good reusable molds of stuff you've made out of clay, I would definitely recommend this stuff, just remember that the mold will be pretty stiff when it's done. Like... For reference, think of a mold you might use for fancy cake shapes or for melting chocolate; it'll be *slightly* stiffer than that.

Good product

This was the first time I ever made a silicone mold, and was scared! I was worried my crystals would get stuck lol. I used my crystals and sphere holders to make my pieces, and it was a success!! Easy to mix, and use with no issues at all. I'll definitely be getting more to make new molds.

fun stuff don't be intimidated!

yes it was a little scarey, freaky at first. always is when you are trying something completely new. but its not a thing at all. super easy to measure and mix. i made 2 molds. 1 with guitar picks and 1 with a toy 12" guitar. just unmolded this morning. they are perfect. exactly what i was hoping for. my plan is to use the pick mold for epoxy pours & guitar for concrete pours. i bought the 1.1lb jars, still have 1/2 a bottle. cant wait to make more molds for concrete! i will be purchasing more of this stuff for sure!

fun

I liked this product very well. I wish there had been a bit more instructions as I did not know it would be best to order a spray release. The finished product is a bit stiff, I used to mold chocolate so I would probably use less and not make such a thick outer cup but that is trial and error. But overall it did the job it was very quick and fun. I would definitely recommend. Ease of use and speed at which I received both get a+

Great stuff.

Make sure the measurements are 1:1 and you will be in the gold. This stuff is good enough to make some wh40k molds. Comes out great.

Makes a perfect copy!!!

So I got this to be able to make silicone molds of things I would like to make using Epoxy resin so I tried it out on 2 of my rings they came out super perfect and extremely detailed I couldent be more happy with the results! I totally recommend this!!!

Sticky mess.

Did not cure, sticky mess. $40 down the drain.

Great Molds

Used for making molds. Very strong a durable molds. Must use a superior mold release agent with this product but it is well worth it.

Exactly what I hoped for

First time mold making. The finished mold had a nice firm texture with smooth shiny surfaces - exactly what I had hoped for. Wish it was a bit clearer so you can see the blanks easier, but it cured without any bubbles.
