And epoxy binds to aluminum just fine ? Epoxy is weird. What solid material does it NOT bond to ?

  Teflon.

    Yummy, my favorite!

      Actually should be mostly fine since it’s pretty inert, unless you eat the stuff used to make it.

        Like, actually making food atop a non-stick surface that flakes.

  Polyethylene, like they use in food containers. Virtually nothing sticks to it unless specifically designed.

  It does not bond to polypropylene and other low surface energy plastics

    Terminology question - I understood those to be "high-energy" surfaces, because the chains are strongly bound. Is it a typo, or am I wrong?

      It is really called low energy, it refers to the low attractive force of the surface, liquids bead up and do not wetten, in epoxy that results in small contact area and a weak bond, on a high surface energy material it flows into all the crannies and has enormous contact area and a strong bond.
