metal adhesive?

I'm not looking into a certain brand, but examples are welcome, because the chances are slim I'm gonna find them where I live.. so, what should a metal adhesive contain/be made of in order to allow me to glue 2 metal pieces securely?

I have tried a 2 part compound, but it is mostly plastic in nature.. doesn't look metallic when cured.. it is strong, but not resistant to shearing forces.. I need something to allow me not to use rivets or screws and keep a clean look. I do have rivets and screws though..

Quicksteel seems to be working on 3xNES but I haven't tried shearing forces with it.

Its a putty with 2 parts that don't activate until you mix the parts together. Its like a eggroll (only example I could come up with) one parts is wrapped around another and they play nice like this. But when you mix it all up it starts to set in about 5 minutes and you can press it into cracks and hole and stuff. Then when it fully cures you can sand, drill, paint, etc just like metal.

Seems pretty strong. I'll have to run down to the basement and snap some photos for you. I got the stuff at Wal-Mart in the plumbing section.

how are you trying to join the metal?
btw ur Sig fits in here Bopher

Well, I'm gonna be making large scale remodeling of my case and I need options as there are some places where I would rather not have nuts, bolts or rivets sticking out. I'm gonna be joining large surfaces, with a narrow section in some places (5-7mm), maybe even different metals: aluminum, sheet metal, the case steel.. In the worst case, I'm gonna be gluing with a 2 compound metal weld product that sets in 5-10 minutes, and rivet it too in that time frame :| I hope it would get plenty strong that way.. But there would be rivets there then, and I would like a flat surface..

JB Weld is the sh!t.

I've used it a bunch to fix tanks. The stuff is super solid.

I've used JB Weld as well and I have to agree with Commando on that. i would probably say go with that if you're gonna sandwich it between 2 piece together. If its corners then the Weld will work to but so will the Quicksteel I mentioned before. Short of spot welding parts together. Maybe a couple pics of where we need to be thinking and how we need to be thinking could help.

I bought some local brand of metal/plastic weld (poxipol.. the only one available). I'm testing to see if it holds nicely enough. I bought 40 nuts and bolts too.. thanks guys for help. If I ever see JB weld, I'll buy a dozen. But that won't be available locally. I'll remember Quicksteel too. +rep to everybody who cared.

I was thinking If you are joining flat faces together you could use slovent. I'm not 100% sure if this works with metal but it sure works with acrylic

why not have a look on ebay (if you use ebay) there is loads of them and I think there cheap but dont know. :banana:

Well, I don't really know of any substance that would act similarly on metal... on the solvent reply :) Metal and acrylic are kinda different.. If you find a substance that acts like a solvent for steel.. it is going to be hard to procure, to say the least.. cause it would be an acid.. and a strong one. No more coming back to sheet metal form if I would use that.. Acetone or chloroform is a good solvent/adhesive for acrylic, but I have never heard of one for metal. :) I think.. :)

Buying from ebay would also be a bit overkill.. for now. Would pay like 15$ minimum for shipping. But that is not a bad idea actually.. If I can find a way to order them through a company, then shipping and customs won't be on my head.

For now, I'm bending metal into shape, using a hammer, scissors and a bending thingy.. Then come the holes, bolts, nuts.. and as a final measure, and for making the metal work sound deader, I will use the 2 part metal adhesive. I have tested for strength and I'm almost satisfied. I waited a few minutes and the bond was strong enough on a few square centimeters to have to flex my muscles to break it. Note that it is written that the bond hardens in 15 minutes, but cures in 24-48 hours.. If that is true, I should be happy. For now, I'm busy bending sheet metal and making stuff that isn't supposed to go together.. go together :)

Where are you located? JB Weld is available at Wal-mart, Home Depot, or Lowes.

Far away.. central Europe.. a little to the east :) No such named product here.. But there are similar. That's why I asked about the stuff they are made of. So I could find something similar myself :)

I would recomend using a Polyurethane. With metal since the surface are often fairy smooth it is hard for most adhesives to form a physical bond with the metal. So to solve this problem a primer is used on the surface of the metal. Once this dries then the polyurethane could be sandwiched between the pieces of metal.I would recomend you finding an auto glass repair shop and seeing if they will let you purchase some polyurethane and primer from them. If you are curious this is the adhesive that is used to hold the front windshield into vehicles, so it must have high shear and adhesion properties.

Also to note with the polyurethane it will take some time to completely cure. It will usually setup in 30 minutes and require 24-48 hours for a full cure.
