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.

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!

Making my first mold in YEARS, and this stuff worked great! Picked up all the details, no bubbles on the surface or on the mold surface, and released the master and casts easily. It is also tough and tear resistant and my mold feels durable and like it will last. It was a great experience to use and the results are all I could ask for and more! Just be very, very sure your mold box is of appropriate material and is absolutely and totally sealed. This silicone is low viscosity and WILL find any holes in your box and leak out (ask me how I know lol).

Takes a long time to cure, but it is super simple to use, instructions were clear enough.

The media could not be loaded. Fast cure time on a 80+ degree summer day. I think that also helped the bubbles escape to the top faster Retained detail. My go-to material for a very quick cure but still capturing detail is alginate. (Used for dental molds) However, the life span is very short and will dry out and eventually shrink- even faster if not wrapped in a wet towel. Alginate does not have the same viscosity and I wouldn't consider it for a pour but after cure it may have a little more flexibility to release without damage. I also wanted the reusability of a silicone mold. One thing to really consider when mold making is sometimes you will have to make a 2 or 3 + part mold. My small scale project had intricate contours, convex, and concave sections that made it harder to pull out. Given the somewhat flexibility of silicone, I still ended up cutting it into 3 parts which was how the original metal was casted. I was worried about resin leaking through the seams but I had no choice. Tried it and leakage was minimal. I was able to scape off the less than paper thin seams that did seep minimally. I did use a rubber band for security. For my tiny stand reproduction, the amount was just enough. I used almost the entire bottle even with finding the smallest cardboard lid for minimal waste and I lined it with smooth packing tape. I have experience making molds with different types of plasters, cements, latex, etc. and an intricate design is a guarantee that you will have to make a divided mold requiring more effort and additional materials. I will still keep that tradition with large scale projects because I don't think anyone would find silicone to be cost effective for anything larger! But... for my first time, this small scale project turned out successful enough to use!

They work fine. The instructions could have been better. It’s fine for a one off use or if you just want to try it out without investing much (me). The kit includes all that you would need to get going immediately. Mine did shrink some on curing BUT I also over mixed them and perhaps caused that.

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!<<
