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 small, round, crater-like holes in the finished coating. What should I do?
Answer: This is what we call fish eyes, and it’s a result from contaminants in the coating. They could come from improper surface preparation of the substrate, from the air, or the air line for the spray gun. Make sure the spray area and substrate are clean and contaminant-free.
