Silicone Mold Making Kit Liquid Silicone Rubber 15A Platinum Silicone Translucent Mold Making Silicone for Resin Molds, Resin Casting, Silicone Molds (21.16 oz)

Very good mold making kit. I had no problems with using this product. It's easy to use, just follow the directions. Make sure you give it a good stir. It does not set up fast so you have plenty of time to work. I poured Part A & B just like the video showed to ensure I was getting an accurate ratio mix. FYI- I ended up placing my molds in the oven on warm (175 F) for about 15 minutes to speed up the curing time after approximately 9 hours. I would check the molds in the oven in 5-7 minutes increments just as a safety precaution. My preference, you can do as you, please, but mine came out perfect. Please see the photo of my molds. I highly recommend this product and will continue to purchase based on my needs. I have no complaints whatsoever.

Super easy to use and dried very nicely. I used a scale to make sure I accurately measured the two liquids and then allowed it to dry for the suggested amount of time. Worked great, and a great amount of product for my needs. No bubbles, very soft and flexible when dry.

It took longer than expected to cure, but the mold came out great. No bubbles. Yeah, you've got to stir it well. Had hoped it would be more translucent. The 1:1 ratio makes it easy to measure. My resin project came out clean without the use of mold release.

The only reason this product got 4 stars is because it came with no instructions on how to use, except for using it as a 1:1 ratio. I had to research how to get good results with this product.On the great side, this liquid silicone makes beautiful molds. Very detailed and bubble free. I've made more than just the two I pictured, and have used them quite a few times before writing this review.A lesson I have learned.As much as you think it's better and less expensive, don't use cardboard. I did on my first few molds, and it leaked if I didn't seal it enough. I lost product that way. Use foam core board. It may not be free like cardboard, but it's worth it. One sheet makes a lot of mold holders.A glue gun is a must. It seals all those crevices. I use 2 different types, depending on the mold I'm making.Don't waste space. If you can get more than one piece in a single mold, do it. I should have added more to the one I had multiple pieces in. I had too much wasted space and product.Because this is clear, it will be harder to judge where the material is on top of the piece you are molding. I use a pin to judge where it is, so I know if I need to add more product or not. If it has too thin and area in any spit, the mold will rip.All in all, I really like the product. I've had so much fun with it, and it has given me many more ideas for my resin creations.

As described.

Works ok but is very small quantity.

This stuff works great! I am a first time mold maker. It's easy enough. Just measure in ml equal amounts of both. Mix together vigorously!!!! For at least 5 minutes. You can add mica powder for color, I add mine in at the 4 minute mixing mark. It turns out great. Then I pour in a plastic container. It degasses itself. I had no bubbles and a perfect mold. I didn't use mold release or anything. I poured one and the item turned out great. I definitely recommend. Just keep stirring!

OK, so I bought this because it was the cheapest one out there that came in clear. Props, it came a whole day early than the original arrival date. There were no real directions but I read in the comments that it was a one to one ratio. I planed on using it all at once so it was not a big deal. Turned out that the mold I made was too big and I ended up not having enough, so I ordered a second set. It came a whole day early again! So I technically got both shipments within the same week. I was able to mix up and pour into the mold on top of the preexisting silicone (which had cured nicely) and it cured as one big piece.I have since used the mold almost 20 times and it is holing up well. The clearness had turned white with use in the area that was curing resin in, but that is ok. I just needed the clearness so I could cut the mold in the correct places when I was getting the original pieces out.The mold has high detail and almost no bubbles in the final product (mind you this was the first time I was making a mold so the bubbles are more likely my fault).I cannot recommend this enough and I plan to buy more (soon hopefully). I cannot say anything for the shelf life as I did not have any leftovers. However, the bottles have a nice plastic plug underneath a screw-on lid so it should do well for a while at least.
