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: There are little pops in the fluoropolymer coating after curing where air bubbles escaped. What should I do to fix this?
Answer: This is called outgassing. In most cases, this occurs with cast iron or cast metal substrates and can be prevented by preheating the part up to 250°F before applying the Teflon® coating. Preheating the part will release all air that is trapped inside the substrate.
