food safe? basic Gorilla Glue 
Modified By Jaedreth  on 1/19/2010 6:03:08 PM)



The post below lead me to believe that all polyurethane glues are inherently food safe. Yet I haven't seen anything on your site or excel's site that specifically denote your products food safe if used, dried, and cured properly.

However, what I'm needing is a bit more specific. I need to fix cracked ceramic in a crock pot. The ceramic is still in one piece, but has an all the way through crack on the bottom (because I was trying to cook when too tired to think straight). Can regular Gorilla glue (not the epoxy) be used to safely fix this crock pot, and would the result be a) foodsafe and b) stand up to the temperatures of a crock pot?

I want to add that there is an enormous difference between something
that is "non-toxic" and something that is considered to be either
"food grade" or "safe for consumption". Things labeled "non-toxic" are
not meant for human consumption - they just fall below a particular
threshold of toxicity.

"Excel" polyurethane glues are, according to the manufacturer, food-safe:

According to this link, Gorilla Glue is food-safe:

Still hunting for other sources of food-safe glues!

Re: food safe? basic Gorilla Glue 

Hi Jaedreth,

Gorilla Glue cannot be used as a filler or a sealer on your crock pot repair.  It is an adhesive that needs to glue two tight fitting pieces together.  Surfaces need to be clamped together tightly while the glue is curing so when the glue expands, it is forced into the pores of surfaces.  This is what makes the bond so strong.  I do not know of any way to clamp a cracked crock pot together with sufficient pressure to hold the surfaces together.  By its foaming nature, Gorilla Glue will foam and expand and fill the crack but it is only doing this cosmetically.

Another concern is temperature.  If you heat a glue line, the strength will decrease when it's at a higher temperature.  Cured Gorilla Glue can withstand temperatures up to 212F.  If higher, the glue line may lose significant strength even when it returns to room temperature. 

If you choose to use Gorilla Glue, it may only be a temporary fix on this specific repair.
