I have plans for a container that requires gluing the joints. Is there a
glue that, once dry, is safe (fda/usda approved) for exposure to edible
products?


Thanks!

Probably not. However government regulations do not extend into what I
do in my own home.

There is probably an industrial specialist food grade somewhere,
minimum order $1000...
There again maybe not.

In that case you need to trawl the web looking for 'adhesive' 'food
grade'. I did this once, but I was specifically looking for a food-grade
silicone to use on milking equipment.

Its possible the FDA have a section somewhere, but I doubt it.

What do you want to fix, and why?

There are a number, some silicone mastics for example.

Me, I just use araldite ....

Thanks for your leads Oz, I appreciate it.

Is Araldite safe to come into contact with foods? I searched all over the
web and all I found was mention that it's unsafe for the UNHARDened resin to
come into contact with food, but I have yet to see anything that says it's
okay for the HARDened resin to come into contact with food. :-(

I would love to use it, but I have to know it's approved.

Mary,

A goggle search for "food grade epoxy" 597 hits
"food grade silicone" 12,000 hits
"food grade polyester resin" 31 hits.
"food grade adhesive" 160 hits.

Maybe you need to study how to use search engines.

You are rude. It's just a simple question. If you don't know the answer,
then don't reply to the thread. Of course I have looked. There are lots of
hits, but I have yet to find an answer to my question. That's why I posted
here, hoping someone kind and helpful (unlike you), could help me. If it's
so easy and you did the searches, why haven't you given me a single page
with a food grade adhesive on it? Because you couldn't. And notice that no
one else here has been able to either.

There's only one specific name brand product I have found, and that's the
Titebond products. Other than that, I'm certain epoxy can be used since it's
used to cover restaurant/dining room tables and bars. But, I need to find a
brand that says "this is fda approved for indirect food contact." And, I've
looked at a thousand pages and have not been able to find one. I have
emailed a couple companies that sell epoxy asking them and have not heard
back yet.

Oh, and I also found hot glue sticks that are food safe. As far as Titebond,
it's made for wood. It might work, might not. And then there are adhesives
that are made for attaching product labels. So, none of these appear to be
appropriate for my application, which needs to be strong enough to hold
together a food container/hopper. It needs to be pretty strong, like a
typical strength epoxy.

Another option is to use rivets out of a safe-for-food material, and then a
safe silicon sealer. That's not my first choice though. That's going to
limit the materials I can use to build the container.
