BBDINO Silicone Mold Making Kit Liquid Platinum 30A 2.42 Lbs Sapphire Blue

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.

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.

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.

This stuff works as advertised I’ve made 2 smaller molds and they turned out great

I have only made one mold thus far and it came out well. I had been using another much more expensive brand and the Bbdino has very different qualities. I had become accustomed to the other brand only needing less than two minutes of mixing and if you waited more than a few more than a few minutes it would start to set up. The Bbdino requires longer mixing and takes at least five hours for a full set up. I checked on it after an hour and it was still in a very liquid state, which made me nervous that I had either mixed it incorrectly or not long enough. But it set up correctly and the end result appeared bubble free and solid. I haven’t poured a resin cast yet but I’m sure it will be fine. It dries quite clear. Another big difference with the competitor brand is that both A And B are clear so when you mix it it looks the same. The other brand has different color part A and B and kind of gives you an indication that it is well blended as the colors meld together.

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.

My first mold using this silicone and it came out perfect!

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.

Llegó bien, con sus instrucciones, y asegurado. La cantidad que necesitaba y precio accesible.

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

Gut zu verarbeiten, schnelle Trocknung. Ich bin sehr zufrieden. Top

Good quality and easy to use. Arrived quickly and in good condition. I recommend it.

facile à mettre en oeuvre. Très joli rendu bleu.
