Smooth-OnSIL-Poxy™ Silicone Rubber Adhesive - 3 Ounce Tube

Just what I needed after buying and trying other products. Smooth-On SIL-Poxy™ Silicone Rubber Adhesive is a reliable, strong-bonding adhesive designed specifically for silicone rubber applications. It works well for repairing silicone molds, prosthetics, and animatronics, providing a flexible yet durable hold. Cures fast depending on how much you use at once and density of the application. Overall, it’s a highly effective solution for silicone repairs!

I’ve always struggled making props with silicone and trying to find viable ways of adhering them to anything else without damaging my silicone or having items tear. SIL– poxy made it insanely easy to affix silicone pieces to just about any kind of fabric. I’ve already gone through one whole tube, and purchased two more since then. The adhesion is strong, the items have held up well in my washing machine with both cold and hot water, and I stress-tested the h311 out of my items by running them through the dryer several times, leaving them out in the heat, testing different solvents and chemicals to see how they would hold up and the SIL-poxy managed to hold up extremely well under all the conditions I subjected it too. Smooth-on makes incredible products all around!

Absolutely THE WAY TO GO if you are trying to bond polysiloxane (a.k.a. silicone) to itself. Cure is within minutes. This product is fantastic for prototyping.This product is for people who have a firm grasp of what they are trying to bond.

There's not a lot to say when a product does exactly what you'd hoped, so this review is going to be short and sweet. It repaired tears in two pieces of silicone that were tearing. If you're familiar with silicone (which I assume you are since you're reading this) you may know that tears just keep getting worse with silicone, if left unattended. This completely repaired the tears (which were extensive) and saved it. I'll be honest, despite the other good reviews I didn't expect it to work, and if it did, I didn't expect it to last. It has been months now, and there's not a single sign of the tears re-opening -- this product is awesome.

Used this to connect separately cast platinum silicone tentacles to a creature mask. Apply, hold, solid for 5 day shoot including underwater. Kept it in my kit for small tears on set. Was able to close up a cut to the glove and get rolling again quickly without upsetting production. Strong smell. Only skin safe once cured. Look at the MSDS

If you've ever tried to repair a silicon breastplate you know that nothing sticks to it - not even duct tape nor the patches you can apply underwater. So I sent for this adhesive. I figured it would be safer to put a piece of gauze over the 3" gash and apply the glue over top of it. It worked, and has held. When I got a second hole, I decided to try it without the gauze. I put a piece of waxed paper underneath the break, applied the glue and smeared it over the rip. Once it set, I flipped the breastplate over and, just to be safe, applied glue to the other side. It has also held up. The dry time is amazing. You have 5 minutes to work with it and in 10-15 minutes you can move the piece. Be careful of the fumes. I don't stick around while it sets.

No adhesion whatsoever. Let go the instant I picked up the two pieces I wanted to join. Super glue is the way to go, not this so-called adhesive.

This works as it should. I do wish there was a different method for applying from the tube like a pump bottle or something.
