Adhesive advice request

[Rumpshot]

I do Geocacheing. I have several different types of containers that I use. One of my favorites is copper plumbing fittings and magnets. I have found that both copper and steel containers that are frequently, or occasionally, wetted will sooner or later separate. I have used super glue for most of my previous stick-ums. Any recommendations on more permanent attachment?

In the case of the copper fittings, solder.

Are you trying to stick the components together? Are you trying to stick the containers to something (if so what)?

Both?

Stick the container to a magnet.

you need a gummy adhesive basically.

There are a number of options there.

Use PVC pipe, end-capped, AND HAVE YOUR NUMBER, CONTACT INFORMATION, AND PURPOSE written on it so people don't call the bomb squad. You can put a magnet inside the tube to hold it in place, a coat hanger to wire it in place, or tar. (tar works great)

Great container Yogi, but does not fit the environment for becoming invisible and readily accessible. If the container is large enough there are standard labels to identify it as Geocacheing.

A lot of adhesives bond very poorly to copper and copper alloys. Read the fine print and choose your adhesive carefully. I've had luck with epoxies made for marine service. Be sure to clean all bonding surfaces with a low residue degreasing solvent. Acetone, MEK, or alcohol work pretty well.

To insure a good bond, use a scrap of sandpaper to sand the wet adhesive into the metal surface. This insures that you get contact with the base metal instead of a layer of oxide.

Thanks, this was mostly the info I was looking for.

Do you mean rub the adhesive into place with sandpaper or to clean the surface with the sandpaper?
