BBDINO Silicone Mold Making Kit, Liquid Silicone for Molds Making 30A Sapphire Blue, High Strength Silicon Rubber 4.4 lbs, 1:1 by Volume Ideal for Mold Casting of Resin/Jewelry/Candle/Concrete/Plaster

My box said “translucent clear”, and it cured as clear as silicone gets, so don’t think you got the wrong thing. This is foolproof pourable silicone, period. This is what “platinum cure” is supposed to be. It self-levels, it self-degasses, it’s great for people with no experience making molds and/or molding objects out of silicone. It’s not particularly sticky and it flows easily into intricate molds. The only price for it practically pouring itself is it takes some patience to wait for it to cure. 5-6 hours minimum. It’s worth it for an end result that looks this great. I got it to layer lighting gels to fabricate filters for small lights and it works great for layering. PROTIP: Don’t tear off the freshness seal, poke a small hole in it for squirt bottle precision. Mix your material by weight, on a scale. It’s much more precise and economical than measuring by volume.

This is hands down the best silicone I have ever used. I have been making silicone molds for epoxy/resin products for over 8 years. Over this timeframe, I have used both tin and platinum-based silicones from major manufacturers such as Smooth-On, Alumilite, and Specialty Resin & Chemical that were listed as “self-degassing” as well as those requiring a vacuum chamber to degas the silicone. The viscosity of this silicone makes mixing by hand extremely easy. My first mold I mixed the silicone by hand and did not use a vacuum chamber so I could determine how well it would degas on its own. This silicone performed the best degassing on its own out of all the brands I have used, but still had bubbles throughout the mold, but not on the surfaces. I do not believe there is any such thing as “bubble free” silicone without using a vacuum chamber. I have made about a dozen silicone molds with this product that ranged in size from 6 ounces of silicone to over 3 pounds of silicone for one mold. Every mold turned out exceptional. All the molds were cured properly and were ready to demold in about 4 hours. After my initial trial of not using a vacuum chamber, I have degassed every other project as I do not wany any bubbles in my silicone molds. If you measure out your ratios properly and mix thoroughly, you should have no issues at all with this silicone. There are a few things to keep in mind when using platinum-based silicone. UV 3D resin printed parts must be thoroughly sealed for platinum silicone to cure against the item. If fully sealing your object is an issue, consider using tin-based silicone as those do not exhibit the same issues with curing and are more forgiving with mixing ratios. Additionally, if the object you are casting in silicone is shiny, platinum-based silicones will render your cast product with a matte sheen. If you require a gloss sheen, you will need to use tin-based silicone. So far this is exceptional silicone and will be my first choice from now on. Only time will tell if these silicone molds will hold up with the same amount of use as my other molds made with silicone products from different companies. I am very pleased with this silicone.

I'm a long-time crafter that makes custom orders by trade. Trying to find the right casting mold from customer request has often been a struggle that has led to customers "settling" on what they get. I bought this product of off reviews alone, hoping I could try my hand at making my own molds. After I received the two-part mold making silicone, it sat in the box for 9 months because I was too intimidated to try it. I got brave last night and gave it a go. My only regret? NOT TRYING THIS SOONER!! It was so incredibly easy to measure/mix. It poured into my handmade forms with ease, completely coating every nook and cranny! They claim it is self-degassing and it totally was! Absolutely no bubbles/micro bubbles to be seen! The mold is very sturdy and durable as well. The only flaws were operator error. I used two separate forms (one made with cardboard and tape, and another made with my son's interlocking bricks). On the one with tape, I had left a crease in the form, so it was not perfectly flat, and this silicone worked so well it picked up the ridge I had left in the tape! I did brush a mold release on the bricks out of fear of the silicone sticking, but did not use a release on the cardboard/tape set up. I had absolutely no issues with releasing the mold from either form upon completion. I really don't think it would have stuck to the bricks if I chose not to use the release, it's just that clean of a cast! There is also NO odor, which is always a bonus when working with crafts. This silicone is definitely WORTH EVERY PENNY!! Now if you'll excuse me, I have to go buy a larger jug of this. I've got molds to make!!

I do not normally leave reviews. fantastic product. easy to use! Grear blue color, cured to very durable hard but pliable product overnight snug fitting mold of internal cavity released easily from glass with mold spray... did not create noticeable. did not have air bubbles or other issues. mixed it gently for a while for about 5 minutes off and on. great product.

The silicone mixes easily and pours smoothly with very few bubbles. It captures details well and works great for resin, jewelry, and small casting projects. The final molds feel strong and flexible. The only downside is that the amount feels a little small for the price. Overall, it performs well, but I wish it came with a bit more material for what you pay.

This performed very well for my project. The single kit was enough to fill a 13” area that had a grandson’s baby footprints on our concrete floor in our garage. Preparation is key to a successful job. I first vacuumed and washed the area with water and let it dry overnight. I then used a concrete sealer on the area and let it cure for 4 days. Then I traced a 13” circle around the area with a pencil where I wished to make a mold. I then made a dam around the traced circle with sulfur-free modeling clay, sprayed the area with a silicone release agent then mixed the silicone liquids together in a clean container (coffee can). I followed the instructions to slowly fill the area from one end to allow liquid to flow into all the impressions and waited 24 hours to slowly peel the cured mold away from the concrete. You may not have to wait that long but I didn’t want to take a chance that it wasn’t fully set up. It turned out perfectly! I had another child’s footprints to mold and repeated ALL the steps with an additional silicone kit at the same time. FYI- you will have to purchase the clay, sealer and release spray separately as it doesn’t come with the silicone kit.

Having worked for a US manufacturer with a line of platinum silicones I love that this is inexpensive, easy to use, almost completely self degassing, and really, as long as you’re aware of potential incompatibilities you should have no problems with this. Sulfur like in some clays, certain vinyl gloves or materials, latex gloves or materials, some super glue or accelerators are the most widely encountered cure inhibitors that can partially to fully prevent platinum silicones from curing. Avoid those, and if you’re in doubt do a small test mix to save time, money, and cleaning up a mess. Temperature can be used to speed cure this material as well, hot conditions give less work time.

I crafted a custom paver mold and have cast about 50 pavers in concrete. The silicone mold shows minor wear, specifically there seems to be some sand size pitting, I assume from the sand in the concrete mix. It's minimal, and not interfering with anything. Unless it outright tears, or some catastrophic issue, I would guess it has another 50 or so castings left. Maybe more. It definitely solved my challenge and I bought more for more custom pavers. I saw the AI disappointment on durability, and I guess that's application dependant, mold design sufficiency, and a good bit of expectations Overall concrete is a tough job, and I'm very satisfied with my silicone mold. Actually way more than satisfied, it's about as ideal as my amature self would have hoped for.

Lässt sich gut verarbeiten und das Ergebnis kann gut Weiterbearbeitet werden

Es muy fácil de usar. Solo recomiendo usar la proporción por peso en lugar de volumen. Da muy buenos resultados. Tengo 5 meses con los moldes y guardándolos como lo indica (lugar fresco sin luz directa) siguen en perfectas condiciones

Non catalizza, andate su altri prodotti questo è buttare via soldi

Produit de mauvaise qualité, le temps de prise est extrêmement long 24 a 30 heures. Même sec la surface intérieur reste collante et poisseuse. Je ne conseille pas ce produit et regrette mon achat. Impossible de faire quoi que ce soit avec le moulle réalisé
