Nicpro Super Elastic Silicone Mold Kit 140 Oz, Liquid Silicone for Casting 3D Resin Molds, 1:1 Mix Ratio Silicone Rubber, Ideal for Silicone Molds - 15a

Just be sure to weigh your a and b components for perfect proportions. Really glad this came quickly. Works well with clay as long as it doesn't have sulfur in it. I use this silicone to make molds and haven't had any issues with it. I will be buying more when I run out.Pros:Good quality siliconeIncludes cups and mixing sticksAffordableCons:Just be sure to weigh each liquid for accuracyI will update this with some of my makings!

it works well, as advertised. i saw people were having issues probably because of an error in mixing proportions. I use a gram scale (with 1/10 accuracy). after demolding, let it sit for some time, as the surface tends to be slightly "wet" initially.

This silicone does NOT dry as fast as the seller claims. Leave mold alone for four days. When it does dry the mold is good. There were a few small air bubbles in the mold. The air bubbles didn’t affect the quality of the mold but potentially could if they were trapped in the wrong place. I may buy again if the price stays reasonable. It does take a long time to dry and the silicone is a little stiff when de molding.

I will NOT buy this again. Tried several attempts at making molds and NONE of them completely cured. After three days of letting it cure it was STILL extremely sticky on top. What a disappointment. Followed their instructions to a T and had horrible results EVERY time. What a complete waste of my money and the hours spent just trying to get one mold right!!!

No issues at all and quick shipping consistently.

I've always wanted to make my own silicone molds but it took me a long time to figure out what I wanted to make. You need to do a lot of research before you do this to see what works and what doesn't work. After a lot of videos I decided to take the chance to make one. The directions were pretty easy and self-explanatory. You mix part A and B and equal amounts until it is completely mixed up and then you pour it on top of whatever you want to make a mold of. Unfortunately I didn't have the right container, it wasn't deep enough for what I wanted to do and I ended up wasting it. I am definitely going to try again but I'm not going to take it out on the company since I didn't do enough research and have the property equipment but it did exactly what it was supposed to do!

I am very new to resin pouring and when I found out that I could even make my own molds for resin pours, I couldn't get this kit fast enough! :) This kit was very easy to work with. Straight 1:1 ratio for mixing which was quite simple. The slow dry-time was also really appealing for a beginner like myself. No rush, no stress.One of my molds did come out with some slimy residue on it even after drying for a few days, but I'm wondering if perhaps I didn't quite get it all stirred together and the little bits that aren't dry to the touch are the parts that didn't fully combine. In which case, that's just user error. In the third photo above, the taller of the 2 molds is the one that had weird wet patches. It could be the depth of it took longer to dry, but I don't think so as parts of the very bottom are totally dry. I really think I just didn't mix it quite thoroughly enough. Oh well, lesson learned!I held one of my molds up to the window so you can see how translucent it is. Not completely see through, but not opaque by any means.The detail that this silicone picked up is incredible!! As you can see on the first photo, the seashell I did came out really well! The smaller one I accidentally sank, so I obviously have some learning to do there. ;) All in all, very pleased with this kit!

The silicone mixes easily and is very low odor. Just be aware I took off 1 star because it is 64oz per bottle by fluid ounce not 70oz as advertised. By weight it is 4.11 lbs, not 4.4 lbs (see pics of unopened bottles). So as long as you know you are only getting 128oz (1gallon) instead of 140oz. Once the final product cures I'll update with details.
