STARTSO WORLD Silicone Mold Making Kit, 10Lb/160Oz Platinum Liquid Silicone Rubber for Mold Making, Fast Cure & Food Safe Silicone Mold Maker, Ideal for Casting Resin Molds/Silicone Molds

This product was easy to use. set up fairly quickly and did exactly what I needed it to. Perfect for using with 3d printing. Released nicely and clean. would recommend.

This worked. Easy to mix, workable setup time. I made some shapes on a 3d printer and then put them in a tray with this mix. I got a great silicone mold.

I tried to cast some parts made of rubber. This silicone will not set when in contact with rubber, so I had to cover the rubber with tape, which worked. Sets up firm, but even in the house I would not de mold the parts for at least 3 full days of drying.

Stuff works good.

The media could not be loaded. Great quality silicone. I've used this brand for several years and have always gotten great results. I love that the bubbles disappear on their own.. less work for us crafters!

This stuff worked great, I think the people that are giving it a bag review just aren't mixing all the way or have the ratio off. I mixed B,A together then went back to the one I poured out of them went to a brand new cup then poured into the mold.

As to the positives, this measured and mixed up really well and I think I have a decent mold although I haven't had a chance to use it. I like the elasticity as I can get things out of the mold easily (original parts). The cure time says 6 hours but it takes a lot longer than that. I would plan on letting it set overnight. One of the things I found disturbing is the packaging and quantity of material. The seller never shows the containers in a way that you can tell how small they are. When I encounter a container shaped as these, I normally assume they are bigger. Realistically, weight is simply unreliable. You will get only one, fairly small mold out of this for any 3-dimensional object to be made. If you are using this for the flat, shallow molds they picture, it may go a bit further. Expensive for the quantity.

Easy to mix and use. Makes great molds.
