Great
I’ve been using this to fix my Halloween animatronics faces. It’s perfect, but it does leave the material a bit shiny, but better than dried and breaking apart.

This adhesive is strong!
Excellent product, used to repair tear in silicone breast plate for a costume, bond is strong, like a silicone weld.

Cosplay
Worked great for attaching a zipper to my silicone body suit. Stunk up the room for a day but well worth it.

Impressive
If you've ever needed to glue silicone together such that it is stretchy and strong, this is the one. I fully expected this to break on the seam or have a nasty hard spot. I was impressed that it was strong, didn't catch the eye, was super simple to apply and use, and fully connected and sealed the silicone test pieces I made to experiment with this.

Not worth it - not sure how I got sold on this
I feel a little bit like a fool. Silicone adheres to silicone - you don't need this. Even to fix silicone molds which is why I got it and how it was "sold" to me. This smells and behaves just like the big tube silicone - pretty sure it's the same stuff. I can't speak to this for sure as I am not a silicone expert, but to me, this feels like clever marketing. Way too expensive for what you get, but it is marketed like it is special silicone adhesive. AND it did not do anything special when fixing a mold, which was the reason I purchased it. Live and learn. You can fix your molds with 100% clear silicone ... you absolutely do not need this. At least I learned I didn't need it. Feeling ripped off. Smooth-on has great products which is why I trusted the people telling me about this stuff. And maybe there is a use case I'm missing.

Perfect for my silicone mermaid tail
I use this on my silicone mermaid tail and it worked FANTASTIC!! Waterproof, quality adhesive, allows flexibility, and highly durable. The color works great in small areas as it's clear

Good adhesive
I was looking for a good adhesive to bond and repair a silicone tear. This product seems to be strong enough though a bit difficult to keep surfaces of the tear close together. That is not a fault of the adhesive. The original material won't stretch as much but is satisfactory in my case.

muy buena opción para prostéticos (ftm)
logro su cometido, para aquella raza trans que busca reparar sus prosteticos, (ftm) no e visto opiniones asi aqui pero se q alomejor esto le puede servir a alguien, parece silicona barata al inicio pero la vdd es q si es muy resistente (la juzgue mal) , por el precio se que es muy elevado pero puede ser la unica salvación y una inversion con sacrificio que puede ayudar bastante al final, cuiden la temperatura de donde dejen su silicona, que si hay riesgo q se endurezca si no esta en la temp adecuada, la mia no llego dura ni nd, pero si siento q llego medio aplastadita, por el camino supongo, pero si, muy buena opcion, y es skinsafe asi que denle mis panas, todo bien

Very expensive but Works perfectly !
I was looking for a silicone to silicone adhesive & Silpoxy was recommended by most internet searches. Pleasantly surprised that this was available on Amazon.in. This glue works perfectly & gets a very good bond. It’s quite expensive but there are hardly any alternatives. I wish the seller should provide an option to buy a smaller size to test out for potential buyers who may want to test this first before committing.
