Teflon® Technical FAQ: Discolored and Brittle Coating

Every day at Intech we receive requests for technical help with DuPont Teflon® industrial coatings.  If you have a technical question, please feel free to call and speak to one of our technical sales representatives.  Once a month, we post a frequently asked question here on our blog. 

Question: We applied Teflon® coating according to the fact sheet and after my final curing cycle, the part looks discolored and brittle. What causes this?

Answer: This usually means the part was over-baked. When the fact sheet states the cure temperatures,  it is referring to the actual metal part's temperature. In order to assure that your part has reached the required cure temperature,  use a thermocouple to measure the part temperature while curing.
