CHANGTIKEJI Silicone Mold Making Kit 84oz 10A Elastic Liquid Silica Gel,Translucent Fast Cure Platinum Silicone Rubber for Silicone Molds,3D Molds,Resin Molds

Wow this silicone picks up so much detail, down to the grain of wood. Have repurchased several times in different sizes. I have been making molds of pictures frames and it work excellent. If you don’t mix properly it will create a weak spot in the mold but if done correctly you have a soft yet very sturdy mold that is easy to demold from and keeps its original shape. I store my molds in a ziplock bag after I create them. The only time I had trouble releasing the mold was on wood that I didn’t prep in advance.

Perfect hardness for homemade picky pads. It's soft enough to pick the beads out while still giving a little bit of resistance. I had tried a different brand of silicone rubber with hardness of 15 but it was too hard to pull the beads out. But this one is nice and soft and, again it still gives good resistance. Easy to mix. Easy to use. Great results. No air bubbles. Good stuff.

I build mini buildings and I have been making mini bricks with 3 small molds I purchased on Amazon. They were nice but I needed to make a larger amount. So I bought this silicon set. I spent a lot of time attempting to figure out the size of the mold. I took a chance that I needed a form 15” by 20” by 1/2”. I used tacky glue to tack down 210 mini bricks. When I decided to mix A & B I added the blue dye. I first used a wooden stick. I then used a drill with a mixer beater & mixed it for about 10 or so minutes to make sure it was fully blended. I left it sit for about 24 hours. When I decided to separate it I was very pleased. The bricks remained in the mold but are easily removed. The only issue is it appears the new bricks are about 1/8” smaller on each side than the original. However the silicon mold set up great.

The shipping was incredibly fast...I made some ice cube molds and some molds to duplicate some porcelain figurines I made when I was a kid. Most of all, I made a mess...I have used silicone for custom-made electrical switch insulators and current protectors. My mistake, this is a good product, it's just not the correct density for a few of My applications. It's good, just not the exact one to work perfectly for Me. Thank You, Amazon.

I've not used a 10A before so maybe this is how this type of silicone cures ... but I doubt it. I was meticulous in my measurements made sure both parts were combined well ... and I was operating in a temperature and humidity controlled environment, but this stuff cured so sticky. It's been over 8 hours now and it is still too sticky to work with. Not happy with this purchase at all. Update: I realize now that it was the mold release that created the inconsistent cure. Used again and it worked as advertised. Should have thought of that before. I was hoping this stuff would work out because of its extreme flexibility and its tear resistance. Also, while not completely clear, it is more translucent than other brands I've used. I'm not sure if it is advertised to do so, however, depending on the thickness of your mold, I'm guessing this silicone might work well with UV resin unless there is some other component in the ingredients that would block it. Not why I got it, but I will be experimenting with that. I would buy this product again. Oh, another thing, it's low viscosity is great too ... I could see using this as a slow cure paint on silicone for flatter pieces.

I calculated 195oz for this skull mold. I bought 3 box kits totaling 252oz of silicone. I mixed in one packet of gold mica dust to all six bottles of mixture. I decided it was better to waste some than need more and have to weigh it to measure it. It was easy to mix; like mixing syrup together. Then I poured it into the mold. The gloves included was very helpful. This mold is not strong enough to hold 45lbs of cement and keep its shape so I use rock pebbles around it in a box to help keep its form. First one came out wobbly looking a bit but the mold worked great for the details. It easily peeled off the cement. No bubbles and I didn’t do anything but pour the silicone in the mold and let it sit for four hours. It solidified. I thought it was stuck to the plastic skull and the outer concrete holder I made but it peeled off slowly and once it was off it didn’t stick again. The silicone took some paint off the original plastic skull but those paint chips washed off. Careful using knife with it. It cuts really easily especially when soft. I made the mold in the morning, took it out mid afternoon, washed it, bought Rapid Set Cementall, poured it that night and peeled it off the skull in 30 minutes. Great product.

Works well! Dries in time frame described. Molded really well into small details. No bubbles at all so far.

I’m writing a revised review after realizing that some of the problems I initially encountered were not entirely the fault of this product. I purchased this silicone to seal large 3D-printed parts for a mold I planned to use in epoxy art. I later learned that platinum-cure silicone can be chemically incompatible with certain 3D-printing materials, particularly TPU. When applied to my TPU prints, the silicone failed to cure at all and remained sticky. In contrast, when applied to parts printed in PLA, the silicone cured as expected. That said, the product does seem somewhat finicky. Even on PLA prints, I noticed small areas that had not fully cured after 24 hours. I also observed similar partial curing on the edges of leftover silicone in a plastic mixing cup. This suggests that the silicone may be sensitive to certain plastics or surface conditions. Overall, this product can work, but buyers should be aware that this platinum-cure silicone may have compatibility issues with some plastics and may require careful surface preparation and testing before use.

El producto es bueno y fácil de usar pero es una lástima que es muy caro para la cantidad que adquieres, así que si eres emprendedor piénsalo mejor pero si lo haces por hobby te alcanza para unos cuantos moldel... Pero eso sí, muy buenos moldes.
