Teflon Technical FAQ: Dry Spray

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: My DuPont™ Teflon® industrial coating has a granular texture with little or no gloss at all. What is going wrong?

Answer: This is called dry spray, and can be caused by several different factors. The viscosity could be incorrect, or it could be an improper choice of thinner, reducer, or activator. Spraying too fast can cause dry spray, as well as the air pressure being too high. The spray gun might be too far from the surface while applying, or the gun may be improperly set up. Always refer to the fact sheets for proper application. 

If you need with a specific question, please feel free to call us at 302-366-8530.
