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

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?
