Gluing Rubber On Rubber

[Kako]

Hey guys, another try, another unsatisfying result. So I roughed up both services, made sure they were clean, applied cement to both surfaces, allowed it to sit for roughly 45 minutes before I pushed them together. After that, I clamped the piece of rubber between two pieces of metal to apply pressure and left it to dry until this morning. I do notice a somewhat stronger bond, but as you can see from the pic, it still pulls apart very easily. I would like the bond to be so strong that the material would break before the glue does, but that's just not the case. From the pic you can see that the glue is stretching as I pull the material apart. Is this normal? Doesn't contact cement ever get to the point where it loses it's stretchyness?I'm somewhat frustrated for something I felt I should have figured out by now. I've been playing with different glues and adhesives for half a month but with no luck.

In the old days, we used heat to vulcanize tube patches to the innertube.

northmount, the tire/tube repair kit sounds interesting, but my project will be to eventually glue the tubing to some type of canvas or fabric so I'm going to need alot of glue and would like to be able to buy it in large quantities. That also sounds interesting about vulcanizing tube patches to the tube with heat. On the directions it says may be activated with an infrared lamp, but I'm not sure what they mean. I do have a heat gun and I think I might just go and do some experimenting with that.

If it were Butyl rubber I would get the glue they use on pond liners. Its made specifically for it.

Thanks Nick, that's an idea to look into. Alright guys, thanks for your input. Off I go again looking for answers.

Going back to shoe trade practice, use superglue. If you don't know what it is, superglue usually works, so much so that a lot of shops use it exclusively. Even with the increased cost of superglue, labor cost wins the race.

Contact cement is not supposed to be stretchy, are you sure it is not rubber or paper cement?

With contact cement, if you leave it open past it's spec (open means painted on the product but not stuck together) you can reactivate it with heat, or you can paint another coat on.
