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 the abrasion resistant PFA over 420-703 primer. We put a final coat of 532-5010 on over the grey. As you can see in the attached picture, we are experiencing delamination of the PFAs down to the primer. What do you think could have caused this? We have a lot of abrasion applications where this coating could be a good fit but I am feeling a little gun shy until I can understand what went wrong here.
Answer: The primer was sprayed on too thick.
