CHANGTIKEJI Silicone Mold Making Kit 84oz 10A Elastic Liquid Silica Gel

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.

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.

So easy to use. Highly recommend for your molds. Easy to remove your casting.

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.

Good quality silicone at a very good price. It cures quickly and does not have noticeable bubbling. It is a buy again item.
