I am looking for a coating that is resistant to moist heat. It would be able to withstand 270F & 20 psi. It is to go over stainless. (Something to dip a tool in.) It needs to be electrically insulating and should be able to make a thin covering (maybe 1 millimeter). It should be fairly hard to the touch.

Any suggestions?

what about a non stick silicone baking pan to fit your piece of stainless - they are typically rated to 450F and come in a variety of sizes and shapes

Beyond my ken - so I'd consult my local pro coatings supplier.

Possibly one of the ceramic coatings, but I don't have any experience with them.

Who is Ken. You have never mentioned him before.

I need to dip a stainless tool into the coating. Something like this, but that can handle up to 270F and 20 psi.

Powdercoat? The stuff is heat-cured at 350-450 (depending on the powder I guess) so 270 ought to be ok.

My first thought also, but it says only good for 200 F. I'm thinking an epoxy, or a network polymer (like Farberware cookware handles), but I don't know how to formulate from scratch. I wonder about Bondo? JB Weld? But silicone like the flexible potholders and trivets would probably be best, I just have no idea of formulation or processing.

Any moving parts on this tool, like slip joint pliers? Or, is it one piece, like a combo wrench?

Master bond makes several high temperature epoxies.

Slight movement. Like a long pair of tweezers, where the working length is 6" and the tips are maybe 3/8" apart.

OK, I can't imagine using tweezers at 270F and 20psi. What the heck are you doing?

That sounds like a recipe for crevice corrosion.

Much more information needed.
