Silicone Mold Making Kit, 10A Super Elastic Jade Green Platinum RTV-2 Liquid Silicone Rubber 2.6 LB for Casting 3D Silicone Molds, Resin, Soap, Candle Wax, Plaster, Clay, DIY Molds - 1:1 by Volume…

Very easy to use. The mix ratio is 1:1 which I always prefer. You can mix equal amounts into two cups. I used a scale and a larger cup and mixed it that way. Be sure to mix thoroughly. Have the item you want to mold already prepared. I pour from one area and allow it to flow over the item and fill. I do not move the silicone around as I pour. Not sure if it matters but it works for me. I can not say hold long to it takes to set up as I do this in the afternoon and leave it overnight. The other bonus is that it's translucent. If you create with UV resins this may matter to you. Do not try a deep mold with UV resin unless you cure it in layers. If the silicone mold is a solid color it will not work for UV resin.

Likes :Very easy mix and pour. This products does degas itself incredibly well. I like that it is sort of clear as well. There are absolutely NO bubbles in my mold.Dislikes:It takes about 4-5 days to really cure to be able to use the mold. It is a little more flimsy than the kind I usually use but it still works if you put it on a hard surface and don’t move it while things are casting.

Best product I’ve used so far

The silicone I was using before was red and took about an hour to cure but it was transferring too much for my liking so I decided to try this one. It is 100% my fault for not reading that is takes 4-6hrs to cure. The one mold I’ve made I left overnight (it wasn’t ready after 3 hours) and it was good to go in the morning.

This product is described as super-elastic, which it is not. The molds worked fine but the final product was not exactly like it should have been. A bit of this was My own mistake, probably should have ordered another brand. But all in all, an item I used with some success. They don't seem to differentiate much between the elasticity from 5A, 10A, 15A, 20, etc. I would, however, recommend this to anyone needing to create custom tool grips and things using harder silicone. Thanks again, Amazon. -Bud

Well packaged (triple closed bottles). Timing as stated was perfect. Colored using https://amzn.to/3Bihxf8 no silicone release spray used, 3D printed and lazily sanded “paper weight mold”.

The project I had called for both full bottles to be used. Since it's a 1 to 1 ratio mix it was simple enough.I placed it a few feet from an electric heater for 5 hours and thought it was starting to gel up. Unfortunately,it was still in its basic liquid form. Next, according to the small instruction sheet I placed it in an oven at 150 degrees. The instructions said to do this for 4 hours. After 3 hours I checked it again and still it was in liquid form. Finally, I've placed it outside on a bucket facing the sunlight. I'll leave it there for a few days and see what happens. This should have cured in 6 hours but as of now, 8 plus hours later, it's still the same liquid I poured originally. Don't believe I'll reorder this again.

easy to make mold.does not stick when unmold.a bit expensive but worth it.convenient the color when mixing to make sure the 2 liquids are completely together.
