Smooth-Sil 940 - Addition Cure Silicone Rubber Compound - Trial Unit

Everything about this product is as stated in the description: no funny surprises, or bad ones. The product is extremely easy to use even for someone who never used silicone before (such as myself), as long as you follow the (extremely easy and concise) instructions your mold is gonna turn out great. I used it to create silicone molds for three dice sets that I can use to make chocolate dice for my D&D players, and they turned out amazing! It's a bit pricey for me, as I live in Europe and with taxes and stuff I ended up paying basically almost double the amount, but for something that is gonna last for sooooo long, it's a good investment. 10/10 would buy again!

The media could not be loaded. Great product. Used it to make a pecan-shaped chocolate mold. Only downside was the cost - it took the whole box (nearly $50 for fairly close to 68 cubic inches of product, if anyone's interested) to make my one chocolate mold, but I plan to use it a lot and couldn't find one anywhere online. All-in-all, I was pleased with the outcome, as this was my first time ever working with a product like this. I do suggest, if you're a newbie like me, that you watch a few Smooth Sil 940 how-to videos to get tips before getting started.

I can not be happier with this product. It worked like a dream. We didn't de-gas it, as is recommended, but after filling the mold, we did bang it on the counter like crazy. Seems to have worked well enough because there wasn't a bubble or imperfection to be found in the silicone mold. I sprayed the 3-D printed mold with non stick spray and that also worked just fine. It was a bit tough to remove the silicone from the 3-D mold, but only because, the way we designed the 3-D mold, there was no good place to grip and pull out the silicone. We were able to pry it out without any real trouble though. We used ours to make a Giant Sour Patch kid, and the gelatin mixer came right out of the silicone mold. It looks absolutely perfect! I can't wait to make up a whole army of Sour Patch kids for our daughter's birthday.

Part B is easily wasted, pls increase its ozs, pls give more details instructions if someone doesn't have certain types of equipment.

Best liquid rubber. NO BUBBLES

This stuff is great. My wife and I used it to make a gift for a friend who wanted a cake shaped like a 20-sided-die. The plan was to make a silicone mold in the shape of half a die, bake two half-die cakes using the mold and put them together using frosting. First I found a 20-sided polygon (icosahedron) STL file on the web. Then, using FreeCAD, I cut it in half and added a box, and printed the half-die plus box in PLA using my 3D printer (a Prusa I3 MK3). I covered the plastic model in food-grade mold release and brushed on four layers of the Smooth-Sil silicone. I added the layers using a technique I found in a smooth-on instructional video, which was to wait about 90 minutes in between layer applications, until the previous layer is tacky but no longer leaves wet silicone on my glove when touching it. After waiting 24 hours for the final mold to cure, baking was easy, and the mold was flexible enough that it released the cake easily - even though the model had a slight overhang. This cake will make a great gift. Thanks smooth-on!

Bubbles are a problem, little bit costly, however details pick up really well.

Me and my siblings used this to make lego molds to use for making gummies. Watch the "The King of Random" video about this, and this amazing guy walks you step by step how to make it. The instructions on this too are clear and easy to follow. Just remember it is very sticky when making it so use something that's not precious to you. But it did it's job and can make perfect gummies!
