Metal on Metal Adhesive; what / where to buy?
Metal on Metal Adhesive; what / where to buy?
(OP)
Hello, I'm typically in the electrical forums so bear with me and feel free to move this post if it's in the wrong spot.
I want to bond one face of a piece of 3/8" aluminum angle to another piece of black anodized aluminum plate. Mechanical fasteners are not my first choice, so I'm seeking an adhesive for the job.
I'm assuming that I'll have to remove the anodizing and any clear coating with a light sanding prior to bonding. This joint will be holding mostly in sheer, with little concern for tensile strength.
I would also prefer if the adhesive had a low clamping time, and a medium viscosity? Not sure how to ask that question; I don't want the adhesive to run away from the joint, but I don't want it to be so thick that it causes a deformation in the piece during clamping. So I guess it needs to be pretty fluid. I've got some PC-7 epoxy that I use for just about everything around the house but I know that making it work for this little project is going to be less than ideal.
What would you guys recommend? I've seen a glue used in the assembly of speaker drivers (magnet bonding to basket) that didn't require UV to cure or anything like that, and it's rock solid. I'm thinking I'm looking for an automotive or aero adhesive but don't know what to try.
Thanks y'all,

Here is one that I've used many times. I would give them a call and discuss your requirements.

Another Manufacturer of epoxy is Dexter Hysol.
They make a series of toughened epoxies.
While they do not have the shear strength of some epoxies, they do have a higher peel strength, which can be important if you get a pull straight up on your part.
check out EA 9309 NA, this stuff will re bend two sheets of aluminum being pulled apart.

I strongly recommend that you Google DOT/FAA/AR – TN06/07, Apr 2007. This is a document titled Best Practice in Adhesive Bonded Structures and Repairs. It explains the mechanisms involved in forming durable adhesive bonds and outlines the basic steps involved. Once you digest that, then select adhesive X or Y.
Failing that contact me at admin at adhesionassociates dot com.
