Silicone Mold Making Kit - .5 Gallon Translucent Liquid Silicone Rubber 15A with Pigment, Bricks - Fast Cured 1:1 Ratio Silicone Casting for Making Resin Molds, with Instructions

Got this to make a grogu to go with mandalorian and the kit came with silicone dye which wormed beautifully for my project and the mold box building blocks came in really handy when making the mold for his hands. The silicone has a smooth feel to it, can be sticky if you don't powder it but a bit of body powder and it's velvety soft. Since I used a silicone mold to cast silicone it was a little difficult to remold but when against rigid materials(not silicone) it released very easily. It does take a bit to get to gel then solid form but that really only matters if you have to sit there for it to cure

I'm still pretty much a beginner but have used at least three types of liquid silicone mold kits and this is by far my favorite - it's translucent, has very few bubbles, great stretchability, and is a 1:1 miscing ratio. So easy, no fumes, no disappointments. Also, I have not had it react badly with other substances. Don't use it in combination with other types of mold liquid, however, as that results in goo.

I purchased this to experiment with making some molds for my shop. It was very easy to mix, very easy to pour. However, it did take quite a bit longer to set than what the directions claimed. I will say it was poured to about 1 inch thick as well, so this was not unexpected. Will I buy more? Not at this time. But that is only because my experiment did not work, not because the product was not good. If I find how to make this work, I would not hesitate to purchase this again.

Works good no issues with it. I even mixed pigment powder in it to make it look blue which worked great. I used it to fill out a Keychron c1 keyboard to be less hollow sounding along with metal weights. You can see the weights as what look like squares all over the bottom of the keyboard. Dried very fast was use able within about 12 hours if not less. I'm not an expert on silicone varieties, but this does appear to be the higher quality platinum type. For a keyboard project like this you will use probably less than 1/2 the bottle, so plenty left over for other things, the weights took up a lot of the space too that would have required a tiny bit more silicone without them, but still should have plenty left over if you don't use weights.

I have made one mold with this stuff, had a good experience, and expect to make more once I get around to designing some multi-part multi-part mold molds in OpenSCAD (because I am a nerd who would rather talk math to computers than take casts of random items around the house). This kit comes with the silicone resin, of course, but also mixing/measuring cups, wooden stir sticks (if you run out, buy some popsicles), liquid dyes for making your molds whatever color you want, a bag of LEGO-compatible bricks for building a retaining wall around your random object(s), and some plastic bags for holding in whatever leaks through the brick walls. I haven't actually used the bricks or the bags, because my 3D printed mold master had built-in walls, but they might be handy for building space ships or something. Heck, you could use this kit to take a mold of them and produce your own bricks! This will of course require a two-part mold, and figuring out how to make that work is left as an exercise to the reader. Or take a mold of your popsicle sticks so you can resin-cast your own when you run out, if you don't like eating popsicles. The two parts of the resin are supposedly equal density, which is great because it means you can measure by mass (I like to use this little scale: https://www.amazon.com/gp/product/B003STEJ4S) or by volume. I found that the silicone will peel off of the included plastic measuring cups easily enough, once it has cured, but I prefer to wipe them out with a paper towel and then use soap and water to get any remaining residue so I don't have to worry about it, later. The same goes for the inverse: mixing epoxy or other resin in silicone cups (I like these ones: https://www.amazon.com/gp/product/B09WDPYD27, but of course with this kit you have the option to cast your own!), which is usually the first thing you do once you have a silicone mold.

I loved this silicone mold making kit!!! This was my first time ever making anything like this. I read the instructions on the back, then I put my item inside of my container and did the rice trick. (So I’d know exactly how much product I’d need) Then I mixed up my materials and poured it in. The box says it takes 12 hours to fully cure, but all the reviews/questions I read said it took them over 24 hours to fully cure. That wasn’t the case for me at all. I’d make my molds around 9PM-10PM at night and then I’d check them in the morning about 12-14 hours later and both of them were completely cured. Since this was my first time doing anything like this, I wasn’t sure how much product I’d actually need. I’m making larger shapes that are over 6” long, so this silicone mix was only enough for me to make 2 molds. Which is my fault because I didn’t know how much I’d need. I definitely recommend this mix. I’d purchase it again unless I can find another product with larger bottles for a better price!

Excelente calidad, lo volvere a comprar desde que lo acabe

Listing says it cures in 12 hours. No, it definitely does not cure in only 12 hours, realistically the cure time is at least 36 hours. It's still tacky at 24 hours and not even completely solid at 12 hours. It feels like it's softer than 15A, it's a little too squishy which make larger molds a little harder to handle. Some of the included pigments aren't that great but I always use mica powder for coloring the silicone. If you can get over those things, it's pretty decent silicone for the price point. I like how translucent it cures, it works really well for UV resin molds. It also picks up mica pigments really well, especially metallic and colorshift powders. Would I buy this silicone again? Most likely but I know now what it's good to use for and what it's not so great for.

So they claim this silicone is odor free and non-toxic which is one of the main reasons I bought it. However when I used it there was a strong ammonia smell as it was curing because it does actually produce ammonia gas during the curing process. I ended up with some nasty respiratory problems due to the gas released. If you go to use this product please use a good respirator mask and use a room with good ventilation. As if that wasn't enough, I had heaps of bubbles in my mold which really just added salt to the wound

Buena calidad pero muy caro la verdad

The best rubber on the market in terms of price. I use the expensive stuff and really seems to me as a better option for smaller molds. Mixes and cures quite fast as well. Using a scale is a must but that should always be the case.

This silicone was really good, but I wouldn't say 100% bubble free. I would use it again though and maybe with a pressure pot.

Absolutely incredible. You can see all the details. Love how flexible it is. When you mix it it has a lot of bubbles BUT they are gone within 20 minutes. I love this product and will buy it again!
