CHANGTIKEJI Silicone Mold Making Kit, 148oz 10A Elastic Liquid Silica Gel for Casting Resin molds and Candle & Soap Mold,Fast Cure Translucent Platinum Silicone Rubber

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 like the quality and ease if use.

Don't use for making molds for freshies. It is great for a rubbery texture. So even though it didn't work for what I wanted it for, it did do what it says. Easy use.

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

EDIT: I've done a lot more research since my first review. Turns out that silicone molds are insanely "picky" when it comes to what they come into contact with. Resin will keep this mold from curing. Works great with PLA though. OLD: Should have listened to others - this thing has been curing for 13 hours. 13! And it's still not done. The inside where it's touching the fine details is as wet as can be. We aren't even talking about anything that big. I'm curing six coin size items.

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.

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.
