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

This mold making kit worked perfectly. The mold came out in great detail and is very durable and flexible in all the right places. Resin releases easily from it and it cured as described. Easy to mix and use overall. Very happy with my purchase and the price was very fair.

Well, I’m a first time user on silicone to make a mold my mold, making skills need a little work but the quality of the silicone was excellent and met all my ex expectations. Would that being said I’ve never used another product as this being my first.

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.

Works well, good for mould creation...

This doesn’t work very well for clay projects. The silicone reacts with the clay preventing curing. Besides that it was a pretty good product.

I like this mold making material a lot. It says it doesn't need vacuum degassing and I made my first mold without vacuuming and it turned out fine but I can see a great many small bubbles in the mold so I have started vacuuming my molds after pouring the mixed resin into them and am very happy with the result. I am making wax injection molds and don't yet have experience pulling waxes out of vacuumed or unvacuumed molds so I am unable to say if vacuuming makes a difference in the quality of the waxes. I can state that the vacuumed molds have a better appearance. And either way the molds cut nicely for removing the model. It is very challenging to mix the material. I pour part A into a small disposable cup and part B into a second disposable cup then weigh each on a gram scale and adjust to match. A write A on one cup and B on the other cup so I don't lose track. I then pour each into a third cup and mix steadily for at least 3 minutes by the clock before pouring into the mold and vacuuming. I 3D print a funnel to attach to the top of the mold because the resin will foam up initially and come out of the mold when vacuumed.

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.

Quality is very good like named brand. Even though I believe one day this will be a named brand. A mold lasted me for a long while before it broke. I was able to cast 32 concrete breeze blocks before it broke

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

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

facile à mettre en oeuvre. Très joli rendu bleu.
