LET'S RESIN Silicone Putty, 1LB/40A Mold Making Kit, Non-Toxic, Strong & Flexible, Easy 1:1 Mixing Ratio for Reusable Silicone Molds, Resin, Soap

Super easy to use, it worked as described. Make sure you use a scale to weigh both putties and then mix well. I was able to make the molds I needed!

This silicone putty exceeded my expectations! The 1:1 ratio made mixing super simple, and the texture was just the right amount of sticky to capture fine details without being messy. It cured quickly and created strong, flexible molds that held their shape beautifully. Definitely feels durable and reusable. For the price and performance, it’s a fantastic deal for hobbyists and pros alike.

Super easy instructions and works perfectly! I will continue to buy this product when needed!

It does cure fast, but so do a number of other putty silicones. I've seen only one brand that offers a slow set putty and I get tons of air bubbles. Make sure to mix both parts completely and as fast as possible. I use small double sided measuring scoops that measure 1/8th to 1/2 of a teaspoon at a time.I use putty silicones for fragile plant material or layering for stronger molds. This serves the purpose decently. It isn't as flexible as amazing mold putty, but it is sturdy enough to do the job.A bit of an observation when casting plants, it does come to trial and error. Some leaves have natural latex that may inhibit curing. Others may gas off as they dry, causing air bubbles or a foaming effect. This may or may not be avoidable. The trick is to keep trying until something works.I use polymer clay and haven't yet used the new molds I made with this product, but I expect good results. I dropped a star because of durability. This does show stress if you bend the mold too far. It is also because I am picky. It can also be fussy to get right.One advantage this product has is it does hold it's shape well if you try to sculpt the silicone to make custom texture stamps, where amazing mold putty would flatten out and lose detail.I also wish bulk quantities could be purchased of this stuff. This is one of the drawbacks I see is having to keep purchasing this at 1 lbs quantities when I desire 3lbs or more.

It amazes me how such a simple idea can be so incredibly useful! In my little realm, I’m the guy who fixes stuff for everyone else (well…I try). When trying to fix a broken radio knob or whatever that glue just won’t work on, I’d normally have to take measurements and recreate it in software and then 3d print it. Now, I just mix up some of this stuff, place the knob in it, wait for it to cure and I instantly have a mold! Then I just mix up some resin and whala! I have a new knob! This is a must have for crafters and handy men.

It cures very fast, but the doughy texture of it tends to create bubbles/imperfections in the mold. I may use this again if I just needed something quick and without much detail, but the imperfections the dough creates are a problem for me with the artwork I make. Because of that I DO NOT feel that it is a good value.It also cures very hard and NOT FLEXIBLE so it makes removing items very difficult! My resin pieces broke when trying to remove them.

very easy to use and work great . I use it to copy moldings where I was missing just 8"

First didn't "weigh" the 2 parts, but mixed by "volume". Did Not Set. My fault for not following instructions. Then I mixed by weighing as the instructions said. No difference, Would Not Set. Stayed soft and pliable. WOULD NOT RECOMMEND THIS PRODUCT.Will not return this product for replacement or refund. I figure its a lesson learned so others may avoid the same problem.
