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

I LOVE this product! I've used it multiple times. Dries within 30 minutes, has about 5 minutes of working time. Will need 2 Kits for larger pieces. It makes about 20-25oz of silicone. CAN be layered, I had a huge piece to mold and didn't have enough to cover the top so waited about a month to finish the process and it still came out perfectly. I mix mica pigment into part A to make custom colors as well, always cured perfectly. Very durable mold. Great for resin crafts. Only problem I have is that it may have too many bubbles for someone's liking. The mold is always perfect but can look a little bubbly.

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.

This mold material is amazing! I've been using alumilite silicone mold to make my molds and it works well but hasn't seemed to hold up as well to multiple uses. I decided to try this material instead. SUPER easy to make the molds and the set up time is so fast! In less than an hour you've got usable molds. I've only had a few areas in molds that didn't set up completely but I believe it was due to debris being on the container for the mold and it hasn't affected how well the mold works. I do find that the set up time of the easy cast resin is a little bit longer when using these molds but the de molding process is much easier and cleaner with these molds than the previous ones. I've already used my full first batch and made about 25-30+ smaller molds for numerous casting purposes. Definitely recommend this product for both beginners and experienced mold makers. The material being some cloudy clear is a big help too because you can see how filled in your casting is or where the colors are going if you use pigments like I do

Wonderful product
