Silicone Mold Making Kit Liquid Silicone Rubber Clear Mold Making Silicone for Resin Molds, Silicone Molds DIY Manual Making (21.16 oz)

Exceeded my expectations! I stirred for 10 minutes to be on the safe side and in 3 hours already looked solid thoughout for the molds i m making I let it sit all night 9 hours and in the morning it was perfect! Very happy and will be buying again!!

Antes de hacer los moldes para mis figuras impresas en 3D (impresora de resina) hice un par de pruebas en distintos materiales, y endurecio bien con muchos plastivos y PVC, pero no endurecio ni en la resina (las figuras ya llevaban semanas de haber sido curadas) ni en plastilina. Asi que si quieres hacer moldes de dos piezas, este tampoco es un producto para ti tldr: does not harden on cured 3D printed resin or oil clay

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.

Silicone did not cure after many days and took me a long time to pour out and clean. I'm not sure what went wrong, but I mixed really well and followed the instructions. Perhaps a defective product?

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.

Very good, but has to be dusted before it clears up
