Non modified PTFE coatings require a high temperature cure around 400 degrees C. Copper will form an oxide at these temperatures and the coating will delaminate. The copper must be isolated from oxygen at the high temperatures. There are several ways this can be done one of which is a thin plating of nickel onto the copper prior to a PTFE applied coating.
