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

[AlotOfReading]

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?

[mjanx123]

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.

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.
