74oz Platinum Silicone Mold Making Kit with Molds Housing & Mixing Cups, 1:1 Ratio, 15A Medium Hardness, Non-Toxic Liquid Silicone Rubber for Resin, Jewelry, Craft Molds

I use this silicone all the time. I have purchased this silicone multiple times and have never had any issues with it at all. I will continue to use this particular silicone. It is durable, sets up correctly, has excellent quality, and it is excellent in value for the money spent. As for stickiness, it isn't sticky when it is used as directed. If I am in a hurry, I put it in an oven at 175 degrees to accelerate the curing process. There are no negative issues with this particular silicone.

Excellent product, perfect for making molds. I've made hundreds of molds and have purchased this kit 6 or 8 times for developing my own molds or for other people. Super easy to use, excellent durability and if done correctly no stickiness with excellent functionality.

This is a good mold making product! I bought a different one and regret it.

Works well, but the jugs are messy. The actual silicone works fine, doesn't take too long to set up either. You need to pay attention to the pigment you want to use if any. I used a powdered mica and it looks great. But the jugs are not meant for pouring small quantities. I would pour it into some of those old style mustard/ketchup squirt bottles. Because no matter what, you're going to make a mess when you pour it, might as well transfer it to a better bottle first.

Worked better than expected. Very happy with the moulds that we made. First time, we were nervous, found it was easy to mix and work with, just followed the directions.

Very easy to use and did exactly what I expected!

The product was very easy to work with and the kit anticipated all the things you might need to get started. I weighed the quantities and found the volumes to be pretty even. I made an ultrasound Phantom which I built in layers with pieces of wood, glass. metal and plastic pieces for my students in Diagnostic Medical Sonography to practice scanning. My new practice Phantom for foreign body identification with ultrasound is ready to sample. I am waiting for our new machines to come in so I can see how well the material transmits sound. My fingers are crossed that it will work thereby saving hundreds of dollars on commercial Tissue equivalent phantoms! I will have to update when I have that opportunity.

The big problem with this product is that it cures with a sticky surface. The mold itself does capture the items being copied well. The finished mold is also flexible. It just isn’t worth the hassle of having sticky molds.

I love the products ! really strong and thick. Easy to use. However i followed the instruction and it didnt really work well so here is the adjustment. (note that you should make a test with the mix and different surface and different time mix and time cure before you poor the whole thing since if i did that i would have wasted 180$ of material) 1- Mix part A and B equal in weight. 2- Mix for like 5 min (cause 3 is not gonna mix enough in big quantity) 3- Poor in a mold (cause it's not thick enough to stand on its on. Its like water) 4- Let it cure for 30 min to 1 hour with the object inside the mold. 5- Remove the object and let it dry for 3-6 hours (since the part that touches the item is gonna stay sticky if you don't let it dry.) 6- Now you can use the mold. Hope that helps. The silicon really goes into tiny details and you can poor many layers if you didnt mix enough to cover the item. I bought silicon mixing cups and its amazing to clean. I tried to mold fimo and other similar paste but it doesnt cure. So dont use that. It cures very well on plastic (like plastic cups). It's meh on leather. Oh and I like that the silicon is see thought so i have more control over my final result. Once the silicon is cured it's non sticky and super durable. If you fold it and there is a little crack then it's gonna tear apart. But as long as its not damaged you can use it multiple time. I needed 3 times the dose here so i found it a little expensive for my project. I dont compare it to other silicon i just think it's expensive for my budget. See ya

This silicone is very easy to use and mix by weight. My molds turned out firm by very pliable. I liked it so much I just placed a second order. The kit of things that came with it was very thorough to begin making molds

I’d buy again

I mixed according to instructions and the outside of the mold was sticky, but the inside was fine.
