Features
- Premium Molds Making Silicone Material LET'S RESIN silicone mold making kit is made of high-quality liquid silicone rubber, which is widely used in mold making and has a higher cost performance, such as silicone mold making kits for casting resins, wax, gypsum, soap, candle, etc.
- Non-Toxic & OdorlessThe translucent liquid silicone we use for mold making is platinum cured silicone, made of safe silicone material, non-toxic and odorless, very flexible, soft, and transparent. Just add mica powder or other pigments, you can easily change its color.
- Self-Degassing & Bubble Free This silicone mold kit has a fairly low viscosity, so you can easily mix and pour part A and part B with a 1:1 mixing ratio. The bubbles in the mold silicone will disappear automatically within 2 hours, without the need for vacuum degassing.
- 4H Curing TimeThe mixing time to make the silicone kit is 5-15 minutes at room temperature, and the full curing time is 4 hours at room temperature, depending on your mold size and thickness. If it is a bit sticky, please extend the curing time of the silicone rubber. Our molding silicone has a shelf life of more than one year. After use, just put the lid back to save the remaining materials for the next use, no need to worry about wasting silicone rubber.
- 352OZ Mold Making Kit: LETS RESIN silicone mold making kit comes with 2 bottles of liquid silicone, each bottle containing 176oz/11 lbs of platinum cure silicone. LET'S RESIN is committed to providing craft enthusiasts with tools and materials to turn imagination into reality. Strictly control product quality and attach great importance to the consumer experience. Please read the manual carefully before use. If you have any problems, please contact us.

What a great product this is! I had never used silicone rubber to make moulds, so I decided to get the smallest kit to try it out. The amount of detail you get is awesome. The key is to mix it according to the instructions and measure it by weight rather than volume. I use a very accurate small jeweller's scale, and my measurements have been on point. As a container for the mould, I have used a very small container that I line with packing tape, that way I can reuse the container, and pulling the tape helps me take the mould out, easily, without damaging the base. One of my favourite characteristics is that it is self-degassing, which means that if used correctly you will not have any bubbles in your final mould. The outcome is a very detailed, flexible, yet sturdy mould. And I will repeat this because I know how people like to skip reading instructions, but unless you read and follow them with accuracy, your results may not be what you desired. If you want to try the product with a small sample -like me- this size of compound will be plenty, but do consider a larger option for other uses. I really recommend the Let's Resin Silicone Rubber!

The media could not be loaded. This is my first time crafting with silicone and it's was pretty simple to learn and use. It's measured by weight not volume, so you'll likely need a small scale. It's durable but flexible. I used it with some tiny dice and it still picked up this tiny details nicely.

Worked well but part of the silicone did not cure, only a small part. I made molds for my crochet hooks and it worked pretty well. As for how they work with my resin Iām not sure as they are still curing but overall I like this product. I will say it does stay liquid for a long time I thought it was not working because after an hour and a half it was still super runny, but suddenly it started to gel up so be patient.

Great product & easy to use. I love making molds & my kid loved making them too at one point in time til grew outta making them. Once cured the mold made is soft & squishy but not tacky or sticky feeling. Easy to use & mix and had no major issues with air bubbles

Thos is great for making picky pads! I mixed all of it on accident, so I had to go around the house to find some sort of "molds". I used 2 Tupperware lids and they worked just fine. šš I did get another mold from Dollar Tree. If you want to make picky pads, get this stuff! Its inexpensive and easy to make.

I figured to make a few trial pours with this sample kit, but the 8 x 8 inch piece I wanted to mold took nearly ALL of both bottles. This is OK, since I bought a MUCH larger kit (about 10x) of the same stuff! >>First off, measuring with a super-accurate scale was really important, since the parts A & B are equal parts by WEIGHT (and I was impressed by How Much More part B was by weight than part A.) >>(Equal parts by Volume won't work- it ends up being a sticky mess that never cures properly!)<< >I mixed 2 times A & B for this same mold having underestimated how much I needed, but the Silicone material allowed this (it was within 10 minutes for the second mix.) >Leveling of the mold was important since it's a FLAT texture that should make for some interesting effects. >After 4 hours the Silicone has solidified but I'm going to wait for about 10 hours to make sure. >Previous attempts with other casting compounds haven't worked BECAUSE: -(1)- Not proper proportions to begin with. -(2)- Not stirred enough to completely mix A & B. -(3)- Mold not level. -(4)- NO Mold Release used and the Silicone stuck to the molded surface and tore! >One of those small "Bulls Eye Bubble Levels" was used to get the mold LEVEL and I used some thin wedges to push under the mold to get that BUBBLE IN THE CENTER before anything else. >I mixed each A & B for at least 5 minutes with the flat spatula furnished in the kit (much better than a thin stick.) >I sprayed mold release -SELSIL- (Take Precautions!) on the surface YESTERDAY to give it lots of time to dry. Looking down through the clear smooth surface of the CURED Silicone there are NO bubbles or parts that are not fully formed on the mold surface. >I Read the INSTRUCTIONS, used a scale that made this all exact, and did everything in advance to make this try a Success. Altogether it took several days of preparation for one small mold, not including how long it took to carve the piece I molded. >>Take Your Time!<<

Was a lot smaller than I was expecting. How ever got here fast. Haven't used yet, but it's let's resin so I'm sure it's good. I only use let's resin things and they have the best in my eyes. With there great selection good prices, and quality of there items.
