BBDINO Silicone Mold Making Kit, Super Elastic Liquid Silicon for Mold Making, N.W. 21.2 oz, 1:1 by Volume, Jade Green, Ideal for Casting Silicone Molds for Resin/Plaster/Wax/Jewelry etc.

My first time creating a mold and this silicone made it so easy to do. The mold also came out wonderfully. I use resin to create the sculpture and it comes out seamlessly, no mold remover needed. Would highly recommend this product!

I do a lot of 3D printing, but I needed to make a part that was both flexible and durable that I couldn't 3D print. Partly because of the shape, and partly because my printer can't handle super-flexible filament. I saw this stuff on Amazon and it seemed like it might work, so I ordered the small kit. I then 3D printed a mold in PLA, then coated the parts that needed to be smooth in XTC-3D epoxy. For the parts where surface didn't matter, I just left the raw PLA, layer lines and all. Because of the odd shape, I had to make a 4-part mold that could be screwed together. Once the epoxy was dry, I mixed up a batch of this BBDINO silicone, being careful to be as precise as possible with measuring. After mixing thoroughly, I took a 60ml syringe and sucked up all the silicone mix and then squirted it through the access hole in the top of my mold until it started coming out of the vent holes. At first it went pretty well, but after a couple minutes the silicone started seeping through the joints of the mold. I figured that might happen since this stuff is pretty thin - which is a good thing for getting it to flow into all nooks and crannies of the mold, but I should have done a better job sealing it. I made a frantic effort to tape up the seams to try and stop the leaks. Fortunately, it worked for the most part. But because a little bit leaked out, I didn't have quite enough to fill to the top anymore, so I quickly mixed up a second small batch and injected that as well. No big deal. I left the syringe sitting in the filler with a little excess in it so it would top off the mold if any more leaked out as it cured. Unfortunately, I got a little impatient and pulled the syringe out about an hour later, before it was completely cured and the "plug" for the hole pulled out with it because it was still soft. It didn't hurt anything in the end, other than to leave a slight dip in the finished surface instead of a plug that could be cut flush. Lesson learned. I couldn't wait to see how it came out. The instructions say to wait 5 hours before demolding, but I did it after a little more than 4. It was perfect! (other than the dip mentioned above). In order to completely remove it from the mold I had to stretch it around parts to get it loose. It's quite durable! I had to stretch quite a bit and it showed no signs of tearing. There was a lot of flashing from where it had leaked into the joints of the mold, but that was easy enough to trim off. They even supply a tool for doing so, though I didn't try it. It picked up every detail of the mold, including of course the layer lines. I had no trouble with it sticking to anything. Even the rough layer lines of the PLA. It came out of the syringe and mixing cups easily too, just by pulling on it. I have to say I am thrilled with how things turned out. I will definitely be using this stuff again if I need to make more squishy parts. Follow up almost 2 years later: Still happy with the quality of the results. While I did finally tear one of them, it had taken quite a bit of abuse before that point. When I poured the first molds, I had quite a bit of leftover mix, so I stuck it on the shelf and forgot about it until the other day. I expected that after having been opened for all this time, it probably wouldn't work very well anymore. Much to my surprise, the new pours came out just as good as the first ones. I didn't expect such a long shelf life, but I'm happy to be surprised.

Easy to use, captures all the details, pretty good at degassing itself, and makes a flexible mold.

I made molds to cast custom parts for miniature buildings. The good: the chemistry works fine and the molds are very, very detailed. I can get a very accurate rendition of the textures. The so-so: the resulting molds are extremely flexible. That has the advantage that the cast parts are easy to demold. That has the distinct drawback that I need to support the sides of the mold for any part that is bigger than about 10 grams or the molds sag and the parts are not within my (admittedly tight) tolerances. Also "scraping" the excess dental stone without depressing the mold is difficult. I suspect there would be less problems if I were casting with a less dense material such as resin, but the dental stone I use is dense enough that the molds deform for bigger parts. And then resin might react with the mold, I have not tested. Lastly my first mold gave me about 15 castings before showing significant signs of wear around the overhangs. Not dramatic for the parts I was casting but you should be aware.

I recently discovered the wonders of BBDINO Super Elastic Silicone for my intricate sculpture projects, and I couldn't be happier with the results. This platinum cure silicone offers a host of features that make it a must-have for any sculptor. The standout feature of BBDINO Super Elastic Silicone is its incredibly low Shore hardness of less than 10A. This characteristic ensures easy demolding of even the most complex sculptures without sacrificing fine details. With approximately 250% elongation, the silicone's exceptional elasticity is vital for preserving the integrity of my sculptures during demolding and handling. One of the things I love about this silicone is its versatility in mixing options. Whether you prefer volume or weight measurements, BBDINO Super Elastic Silicone accommodates both, allowing for accurate and consistent mixing every time. The silicone is perfect for various mold types, including one-piece molds, glove molds, and matrix molds. It captures intricate details with precision, ensuring faithful reproduction of my sculptures in the final cast. However, it's important to note that BBDINO Super Elastic Silicone requires specific curing conditions. It must be cured above a certain temperature to ensure timely curing within the recommended 3-5 hour timeframe. Failure to meet the temperature requirement may result in longer curing times or incomplete curing. Additionally, users should be aware of the material compatibility of their master object to prevent cure inhibition, as this silicone is sensitive to various substances. In conclusion, BBDINO Super Elastic Silicone is an exceptional choice for sculptors seeking a high-performance molding material. Its low Shore hardness, outstanding elasticity, and compatibility with different mold types make it an invaluable tool for capturing intricate details. Just remember to follow the curing instructions and ensure material compatibility. With BBDINO Super Elastic Silicone, you can bring your artistic vision to life with remarkable precision and ease. Edit: 6/25/23 - I wanted to address some reviews I recently read about: -This silicone is very thin and runny which is exactly what you want to flow into the details of your object. -Also this is not a brush on silicone and should be not used for such applications. -Using this in the summer/ higher temps (80F+) will cause this silicone to cure faster than the stated time EDIT: 1/8/24 update - Still my favorite silicone to date. Extremely cost effective and has great shore hardness & elongation. I saw a 1 star video review stating that the silicone does not cure but the user was using 3d printed RESIN which contains SULFUR and WILL CAUSE CURE INHIBITION to platinum cure silicone. DO NOT DO THIS. Platinum cure silicone will not cure when in contact Sulphur. Also this is not a paid review, I make and cast sculptures full time for a living and this has been the most hassle-free and reliable silicone I've ever used.

This was my first time using silicone for anything, and I have to say - this stuff works great! Needed to make candle molds of an oddly specific size so I glued the existing candles to the bottom of plastic cups, mixed this stuff up at the 1:1 ratio (tip from the net: pour, mix, pour into a second container, mix again, THEN pour into your mold), filled the cups, and after eight hours I cut the cups away and the wax candles slipped right out of the cured silicone. Perfect molds, no air bubbles, tested them out the next day and they work great! AND they’re elastic enough that I can roll the lip of the mold down to get a grip on the candle without worrying about tears. (For my purposes any color would have worked, but definitely a fan of the jade color too. No color leeching either!) Definitely going to order another batch, what you see in the video used up *just* about all of it - 12 small candle holders, 4 tall ones, and a wee bit of overpour. PLENTY to use on a larger scale project!

Love this mold maker!

Works great. Used it to make a PU foam easy to release from PU casting. The silicone penetrates the foam and fuse into it, virtually changing PU foam into silicone. Easy to mix, pour and cure

Sehr tolles Produkt Das erste Mal eine Abformung gemacht,hat super einfach geklappt mit bestem Ergebnis. Top 👍

気泡もすぐに抜けて商品はとても良いものです。が、購入先の評価をしっかりと確認されて購入をされた方が良いと思います。いい加減な業者に当たることがあります。

De muy buena calidad, fácil de usar.

I did make a few moulds but quite expensive.

Great product
