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

This dries slow as expected being zero shrink silicone. It dries in about 8 hours. I have other putty that dries in 30 minutes, but the end product gets pretty hard and not really flexible. Let's Resin may be slower but it gives far better results. Flexible, strong, and most importantly, it doesn't get sticky after sitting for a month or two after molding. I have found it easy to use and clean up. I think this product is a beter value than most for the money as I tend to need les to get the same results.

EDIT: !! I AM CHANGING MY ORIGINAL REVIEW!! After doing research on different types of silicone base and catalyst, I found a study of the effects of nitrile, vinyl, and latex gloves. To summarize, this putty does not interact well with nitrile gloves. I used it bare handed and found that it would set up as expected and is genuinely a good product especially for the cost. I apologize for my original review and I guarantee I will be using this product again in the future. I recommend just using your bare hands to mix this putty due to there also being no residue left on your hands after mixing. Again, I am sorry and I hope this is helpful! Packaging says that the working time is 3mins and the curing time is 15-20mins. However, this putty almost never sets up or cures, even with prolonged vigorous mixing. When it does finally harden in the slightest, the putty easily falls apart. Please stay away from this product and look elsewhere.

It's great stuff! If used wisely you can make quite a few molds for small items. One pound is plenty enough for jewelrymakers and most hobbyists. It's easy to mix, easy to shape, and easy to mash onto items to mold them. It's a very forgiving material that allows mold-making to be a casual hobby. It doesn't stick to skin very much, and it's easy to scrape and clean up even with bare hands. After mixing the putty, you get about 3 minutes of normal working time and then maybe 5-8 minutes to fix mistakes. You can also use a nonstick material like burnished wood to flatten areas and fix edges when necessary. Today is my first day using it and I've made 5 molds throughout the day. I found that an exacto or scalpel knife blade is outstanding for trimming the excess material from these molds. Use your thumb to push/roll the excess away from the mold cavity, then slice it off. This thin, folded rubber won't resist your blade at all so you can make amazingly precise cuts. In my photo I showed how many grams it took to make each mold. (I found that a good rule of thumb is to make the backing have 2-3x as much mass as the initial layer. Use pinches to blend the layers into one solid mass.) Since taking the photo, I've filled every mold with more of the silvery epoxy. Can't wait to see the results! The first two molds, I poured epoxy into them within 20 minutes of demolding the original items. Through time, I will research this material more and try to answer the following: 1. How much heat can it take? 2. How does it work with mold release spray? Overall, it's super fun and well worth trying! UPDATE: A few days later, I have an answer for the 2nd question. Mold release spray hardly seems to make any difference. But I also have some advice. You should wash and dry these molds before using them for the first time. If you don't, the oils from the silicone putty might get into your epoxy. This is especially noticeable for small or thin items. The epoxy items cast in these molds were flexible like a gummy. After a few days they did fully harden, but it was a bit nerve-wracking to wiggle them out of the mold without bending or breaking them. I imagine this leftover silicone oil is also why people have problems with UV Resin. So, wash the molds!

Easy to use, makes a great soft mold. Does not get hard.

In all truth, I’m not sure I should be rating this. I am a complete novice when it comes to using silicone molds. My lack of experience, I’m sure, I had a great deal to do with not giving a better review. The instructions were clear, the product arrived on time, and it did what it was promised it would do. I found it to have a weird kind of greasy feeling. It was a little bit tricky, but I got what I needed from it.

I needed to make a resin copy of some trim on something that was far too large to submerge in a traditional silicone mold making kit, and this product worked to make my mold and was easy to use. I did have a few bubbles where the putty did not entirely conform with the contours of what I was molding, but these defects were small and easy to deal with (i.e. by putting some clay into those holes before pouring epoxy into the molds). It only takes about 20min for this stuff to work but I was afraid to remove the mold that fast and simply let it do its thing over night and made the mold before I went to bed. Very good quality product and I will be using it again.

I first tried mixing up some and waited 20 minutes and it was still not remotely cured. I waited 3 hours and still not cured at all so I disposed of the mix and tried a second attempt. Only this time I put some of part A into one baggie and an equal amount of part B into a SEPERATE baggie. I ran a cup of hot water through my keurig coffee maker without a coffee pod, just hot water no coffee, and put the sealed baggies of part A and B into the cup of hot water for about 90 seconds. I quickly removed the warm putty from their baggies and blended together until uniform in color, I didn't over mix, just until uniform in color, no streaks. This resulted in a well cured mold within 20-30 minutes. It works but parts should be warmed before mixing. Not sure if putting in microwave would work or somehow affect the reaction.

We both use this mold making stuff all the time. It's super easy to use and the molds hold up to use after use.

Der erste Versuch war nicht gut, der zweite deutlich besser. Ich habe sie beim 2 Versuch abgewogen mit einer Feinwaage, das Ergebnis war fantastisch

Bargain, good quality product, very easy to use have made lots of moulds to broken ornaments with good results,,,

Wow I've been trying all kinds of products but this actually works. It's a putty so you can form it around the detailed bits you are moulding. It is a putty so it's not liquid like others and the model doesn't sink into the silicone. I love it and will definitely buy again.

I purchased 3 products (see video) thru Amazon, "Lets Resin Silicone Putty" (incl. 2 jars, each 0.5Lbs or 227g), "Wycoon Epoxy Resin" (incl. 2-bottles, 8 fl oz or 237g each, crystal clear resin & hardner), and "Lets Resin Chrome Markers" (incl. 3 high gloss markers, gold, silver, copper). All products arrived on-time or ahead of schedule. I used these product to repair the raised chrome lettering on the side of my boat. I used the silicone putty to make moulds of 2 undamaged letters found on another part of the boat. I poured a batch of the epoxy resin into the silicone moulds to cast the new letters. Finally, I chromed the new letters with the silver chrome marker. All 3 products performed as advertised, and I was more than happy with the results of each. The chrome markers were amazing, producing a highly reflective surface that rivalled the appearance of the original chrome lettering, as demonstrated in the attached video.

A comparación de las otras masillas de silicón, creo que esta marca ofrece más producto por menos dinero,tarda un poquito más de tiempo en catalizar la mezcla lo que te da tiempo de lograr un molde que logre todos los detalles de la pieza, el único incoveniente es que, una vez curado el silicón es muy muy frágil, si le vas a sacar molde a figuras con detalles, extremidades etc lo más probable es que solo puedas usar el molde una vez, otra cosa, si por algún motivo dejaste algún espacio sin cubrir y quieres aplicar otra capa de silicon ya una vez curado, no va pegar, tienes que hacer el molde en un solo intento y de preferencia solo usando una misma bolita de Silicone putty, entonces hay que calcular bien el material, para que salga a la primera. Aún así considero que es un buen producto para hacer moldes que no serán de uso rudo y de preferencia figuras básicas, lo volvería a comprar sobre todo para lograr impresiones o sellos de texturas, usos de ese tipo, sobre todo de emergencia para no recurrir al silicón líquido.
