Smooth-On Ecoflex 00-50 Platinum Silicone 2 lb Kit - Clear Silicone Rubber - Casting, Art, Craft, Model - 3 Hr Demold Time - Low Viscosity - Shore 00-50 Hardness

I was able to easily copy a few dice from a board game that had been lost. Unfortunately I'll need a pressure pot or vacuum chamber to get the bubbles out of the resin, but the silicone worked perfectly.It's soft enough to easily remove the dice but very strong. I imagine I would be able to make a ton of dice from a single mold.A word of caution: SLA resin does inhibit this platinum cure stuff, so you will need something like inhibit X, or another method to create the mold from a 3d printed master.

Somewhat fragile, for the softness not too bad. I think I'll switch to urethane for better grip and durability in robotics applications. For *other* applications this stuff is amazing. Just wish silicone wasn't so expensive.

This stuff is exactly as advertised, check their website for more details but it works like it says. The only downside to this is the cost is pretty hefty.

This is easy to use. 1 to 1 mix. I did not need much for a small project and now have a lot left over so I will have to think of other uses for it but I am sure something will come up.

Since I couldn't find full size 3D molds for chess pieces, I ordered this! I was so nervous as the first silicone I purchased didn't quite work for what I was needing... I am in LOVE!!!!! I will never use another product to make my molds! I went from a 12hr cure time to 3hr...its so flexible but doesn't feel like it's going to tear. I am no pro... Actually 2nd time ever making my own molds so I am still figuring out how to make my molds smaller and less waist full... But I am happy!! I can finally pour a full side of chess pieces at 1 time!!

I made some dryer balls and they came out perfect.

Price is good for something real small and someone looking to do a couple of castings, it’s not what I use to get from Smooth-on. Not my mistake because this was the same product I have still on my shelf, but it’s been 8 years. It’s opaque clear not the hard yellow rubber it use to be. To soft for what I’m doing. Not saying it’s junk but not the same product I used before. Took more than 3 hours to cure too. If your into a time frame, then this is not your choice for that.12 hours minimum. It’s not because of it being mixed wrong, that’s the cure time that I recorded. Power mixed and vacuum chambered the product to get all the air bubbles out and still was 12 hours. I’m sure not new doing molds. Disappointed on what was once a perfect product. Either smoothed-on changed the formula or they changed the name of what I once got from them. It takes hours building a mold to find out it’s junk. I’m into mine 36 hours just on the mold building for 1 side.

Perfect and easy to use. Great cured texture
