Heat and water-stable adhesive

[1190R]

I'm trying to bond two metal surfaces with glue that can take the hot water of a dishwasher. I tried Crazy(cyanoacrylate) glue but this failed on its first dishwasher cycle. Any other ideas out there?

more info maybe?
have you tried epoxy or the glue that they are using to glue automotive panels on ?

+1 The heating element on the bottom is the same type of material that is on an electric cooktop element. That area can get really hot. (Its not just the water.)

 

[The Cobbler]

so you're trying to glue the element back on?
sorry, I'm confused I guess

The OP mentioned they wanted something that holds up to hot water. I mentioned the heating element because there is also that radiant heat in the unit. (Sometimes folks forget that there is no hot water in dishwashers - only cold water and the heating element warms everything up.)

... adhesives on or near that heating element would be an issue.

I'm trying to glue a stainless steel sink sponge holder to a neodymium magnet and have it survive the dishwasher to keep it clean. The crazy glue failed its first wash even though on the top rack

I've got JB welded parts on the lower rack of dishwasher good for 2 - 3 years now.

Drill a hole in your rack holder and use these magnets instead?

Silicone. It works for engines, it works for pools, it works for stills. heat and water resistant, non toxic, and widely available.

You're welcome.

you can't, the only 2 ways are thru bolt or weld it.

I have JB Weld holding parts of my tea kettle together. Seems to be holding ok with heat and hot water.

For the sponge rack, I’d be tempted to go with a larger, weaker magnet. Something to cover the whole back of the rack, and something like 3M exterior mounting tape to hold it in place.

I use Marine Epoxy for stuff like this. You can get 5 or 2 hour versions at local home stores. Check the plastic material imprint in the holder and you can confirm the compatibility.

Something like this should also be top rack in the dishwasher. Rare earth magnets don't like heat, but the temperatures on the top rack should be fine.

But Trump said magnets don't work under water...

Thanks to everyone who recommended JB Weld. Going to try their marine epoxy and report back
