Smooth-On Mould Star 20T Silicone Mould Making Rubber - Trial Unit

I got this first to make a mold for a small sculpture I made in plasticine clay. I used about 2/3 of the product on that two part mold, and I got great results. I then used the rest to make several smaller molds for resin casting various trinkets. I used the last of it to cast rubber feet for a vibration table, which also worked great. Since it's transparent, you can add color to it and use it to cast rubber items. I did have a problem where I tried to use some resin dye to color a batch I used for three smaller molds. Something in the dye prevented it from setting up, and it stayed a viscous goo for days before I finally cleaned off my positives and tried again. I confirmed it was the resin dye by adding it to half of a tiny batch. My recommendation is to use powdered pigments like chalk pastel or mica powder, or to test a small amount first before mixing up a full batch.

molds turned out great and have made many prototypes. molds are still as good as when they were cast.

Arrived really quickly, and the product itself was perfect for what I was doing, however, the shape of the containers makes it difficult to pour neatly.

I really like this, I’m new to sculpting , and I’m learning how to use monster clay. I want to sell my art , so I make a mold of it and then cast it with Sculptamold. This works great ! Very easy, and it cured/hardens quick like the box says 30 minutes , it’s super sticky though I wasn’t wearing gloves so it got all over my hands , but I just let it dried and then peeled it off. I Ofcourse wish it came in a bigger size that wouldn’t break the bank for me ! The mold comes out bendable rubber which is fun because I’m sure it should last , and I just need to make a 1 side mold because I’m gluing the smooth side to a canvas .

Wonderful product
