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.

I love this stuff, I want to get a full size kit. This is the trial which was enough to do a couple small molds and it's so straight forward and easy. Zero bubbles (use the fridge) and super easy to demold. Love it.

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!

I've been using this product for about a year now. The quality of the finished mold is superb. It's NOT bubble free as claimed so degassing is needed for perfect copies. The molds do not break down in storage (at least so far after a year or so) like the Alumilite Pink Amazing Mold rubber does. That stuff is garbage and this is better in comparison to that product. The biggest issue with this product is that it does not work with making copies of 3D printed objects that were done with UV resin. This stuff DOES NOT like 3D resin and the molds will come out sticky and distorted. Your original will have goo all over it and will have to be cleaned. Not easy to clean this stuff off either. If anyone has an alternative to use on 3D resin printed objects.. please reply. Thanks

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!<<

My husband has successfully made model plane parts! It works well. The directions are apparently easy to follow! A good buy!

I love let Resin products. This is the first time having issues with any. Says 4hr cure time, yet I have made 8 molds at room temperature- cure time ranged 8-12 hours. The thickness at max 1in, depth 1-3 in. unfortunately I bought the largest container - 11 lbs. Really hinders time management. End product is great but 2-3x time to cure. Not happy about it. Would love replacement if offered.
