Good

I really like this silicone for small molds. But it’s too stiff for larger items

Muy satisfecho con el material👍

I liked the bigger size and had a good price.I liked the 30a firmness of the cured product....worked better for me than the 15a rated products.

Well, to be honest, I’m a little disappointed and frustrated because I had to go through several failures and a lot of testing with this particular silicone before giving up on it completely. Basically, if you’re looking to make silicone molds of your 3-D printed resin parts, don’t buy this product. It is definitely not compatible with at least two of the elegoo 3-D printed resin Formulas. I went as far as sealing the prints in rust oleum clearcoat with three coats, waiting 24 hours for to cure and then washing off any residue with soap and water than drying before pouring the silicone mold, and it still failed so I would call this resin very highly reactive with other materials and I won’t use it ever again, so all in all this was a very negative experience for me however, if you’re just pouring bolts of very unreactive things then I think this resident is fine as you can see from the photos it did cure but anywhere it was making contact with the surface of the 3-D resin prints. It failed to make a perfect copy and was left with a gooey uncured surface, which was very disappointing so that is why I had to give it a low rating. Update, after much research I’ve discovered that it’s a lot more difficult to find a platinum based silicone that works with resin 3D prints. Check out siraya tech defiant, that’s what I’m going to do.

Great price point and silicone, cured within 24 hours in 65 degree weather. No bubbles in any of the 12 molds I made. I wish it came in clear so I didn't have to buy multiple brands.

Makes a detailed flexable & reusable mold. Mixes nicely

I mixed this product by weight on my scale. Once I poured it, I let it cure for 2days I was out of town. It had bubbles which turned into holes and it started to leak. Gave it 3more days to "cure" the inside was still wet. I'm back to square 1.
