BBDINO Silicone Mold Making Kit, Liquid Silicone for Molds Making 30A Sapphire Blue, High Strength Silicon Rubber 4.4 lbs, 1:1 by Volume Ideal for Mold Casting of Resin/Jewelry/Candle/Concrete/Plaster

I'm a long-time crafter that makes custom orders by trade. Trying to find the right casting mold from customer request has often been a struggle that has led to customers "settling" on what they get. I bought this product of off reviews alone, hoping I could try my hand at making my own molds. After I received the two-part mold making silicone, it sat in the box for 9 months because I was too intimidated to try it. I got brave last night and gave it a go. My only regret? NOT TRYING THIS SOONER!! It was so incredibly easy to measure/mix. It poured into my handmade forms with ease, completely coating every nook and cranny! They claim it is self-degassing and it totally was! Absolutely no bubbles/micro bubbles to be seen! The mold is very sturdy and durable as well. The only flaws were operator error. I used two separate forms (one made with cardboard and tape, and another made with my son's interlocking bricks). On the one with tape, I had left a crease in the form, so it was not perfectly flat, and this silicone worked so well it picked up the ridge I had left in the tape! I did brush a mold release on the bricks out of fear of the silicone sticking, but did not use a release on the cardboard/tape set up. I had absolutely no issues with releasing the mold from either form upon completion. I really don't think it would have stuck to the bricks if I chose not to use the release, it's just that clean of a cast! There is also NO odor, which is always a bonus when working with crafts. This silicone is definitely WORTH EVERY PENNY!! Now if you'll excuse me, I have to go buy a larger jug of this. I've got molds to make!!

Wow, this stuff surprised me for sure. But it's super simple. Mix evenly and throughly. Degassed I'm vacuum and poured slowly. Covered and didn't give into temptation to mess with it. Dried completely 1 hour before expected. Way better than that Hobby Lobby stuff. Will DEFINITELY buy again!!

No cure inhibition. I've bought this more than once and I'll continue to do so when making molds of 3d-printed items. Works great and I've not had a need to look anywhere else.

I have only used one other brand of silicone before. This one seems to be much stronger and just as flexible as the other brand.I am impressed with it.Degasses well as long as it is not too warm when it is setting up. (without vacuum or pressure chamber)Easy to use and mixCaptures ever detailGood removal of objectsI have had issues with tackiness on some pours but I am not 100% sure if it was do to user error. One of my pours is into another silicone mold and that mold seems to be the one I have the issues with. The instructions say not to use with "tin cure silicone" and I have no idea if my mold is tin cure or not.I wish it did not take 6 hours to set up though.Over All great for what I am using it for. (Mainly making silicone parts) - O-rings, gaskets, standoffs, etc.

Price is right, this stuff molds really good, molds seem durable, the color blue is just beautiful. I can honestly say, it's the best silicone mold maker I've ever used.

I used this silicone kit to make prop ice cubes for a film. They look and feel great, they won't melt, and they are quiet. Exactly what I needed. They don't float like real ice, but I'm not using them in drinks or anything. I'm sure I could figure out how to put air bubbles inside them if I needed them to float.The directions are simple and straightforward, so be patient and precise with your measurements. Fill your mold with water first and then dump that in a measuring cup to figure out how much silicone to use. This way you won't waste too much of it. Clean and dry your mold thoroughly before pouring the silicone in.If you've got the time, don't rush letting it cure. Just pour it into your mold and check it tomorrow. Let your mixing and measuring devices sit that long also. It is much easier to peel the dried silicone off than trying to wipe up the excess before it has cured.The price is reasonable for this kit, especially when I researched buying prop ice cubes v. making them myself. I paid just under $40 in July '24. I'll buy it again when I need to make something else.

I normally used oomoo in the past and tried this out for volume reasons.Very sturdy and flexible silicon. Resists tearing also. I single pour casted large items and cut a side to remove. I’ve casted over a hundred items in cement and they have not torn from either details in the cast or stretch the cut for removal.Unless very well mixed the uncured portion will settle onto your item you’re casting and ruin the pour. It also did the same one time when I used my specific mold release, Mitreapel. I stopped using the release and it was not an issue without. I was however casting a very smooth item but the boards I used for my mold box were made of MDF and it was not an issue either.A difference with this and other silicones I’ve used is the color mix indicator. With oomoo you get a pink and a blue, to a very obvious purple when properly mixed. This product however is one blue and one clear so there is not a obvious indication of it being well mixed. As stated above I recommend very very thoroughly mixing this because of the previous mention issue with it being pretty unforgiving if poorly mixed. The work time is pretty long (at least 20 min). It would behoove you to take some extra time to make sure you’re not going to poor any unmixed product in your mold.Over all though great silicone for a good price when it goes on sale (very regularly on sale). I will continue to use this product at this time.
