Teflon Technical FAQ: Outgassing

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. 

If you need more help, call us at 302-366-8530.
