8oz Silicone Mold Making Kit, Fast Cure Liquid Silicone Rubber | Easy Mixing, Translucent Flexible Platinum Cured Molding Silicone for Casting Resin Molds, Silicone Molds, Ideal for Beginner

Great molding compound, easy to mix, and provides fine detail

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).

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!

These are incredible!! Easy to use, sets fast and leaves absolutely no bubbles on its own.

I found it a little hard to understand how to work it but it'd good quality

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!

I needed to make an oring for an old fire extinguisher that parts are not available. I made a mold and first tried a resin that was rated 65. It was too stiff and broke installing it. I then used the same mold with this resin and the oring was able to be installed and seals perfectly.

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!<<

Easy 1:1 measuring ratio. And a very durable final product. Casts so detailed i sanded the Master Form and all the cast pieces were ready for paint immediately.

First time working with anything like this and it was very easy to work with

très bon produit bien respecter les proportions , correspond à la description

This product was so easy to use, this coming from someone who has never used similar products before. I had no issues at all. Bubbles if any, were small and few but did not affect the mold. I took away one star because clean up was horrendous. I followed instructions of using warm water and soap and that created a huge sticky oily mess much like Vaseline that i just couldn't get rid of. I had to use acetone to undo what warm water and soap did. I later found out, just wiping the stuff off with toilet/kitchen roll (tougher paper) paper worked. I finished off with just running my tools under water and wiping it dry.

Odourless and pretty much self degassing - a joy to use Mix 1:1 by weight, 4hr cure time.Lack of fumes or smell is important to me as I work in a domestic environment.
