Teflon® Coating
Teflon® industrial coatings are fluoropolymers made by Chemours that have a combination of properties to improve performance of a wide variety of parts such as release for molds, is non-stick, heat resistance, increases lubrication, and is excellent for corrosion protection.
- Teflon®-S Coating
- Special one coat blends of fluoroplastics that provide excellent toughness & abrasion resistance.
- PTFE Coating
- PTFE non-stick coatings have the lowest coefficient of friction & highest temperature resistance at 500°F and a melting point of 627°F. They also offer good abrasion & chemical resistance and can be applied to aluminum, carbon steel and stainless steel.
- FEP Coating
- FEP coatings differ from PTFE in that it melt flows and is thus non-porus. They provide excellent chemical & corrosion protection and can be used up to 400°F.
- PFA Coating
- PFA is a resin very similar to FEP in use, but PFA can be used at even higher continuous use temperatures (500°F), can be applied thicker, and has greater toughness than PTFE & FEP. PFA is useful for the paper industry where it helps to improve the efficiency of paper mills, pulp mills and other paper converting industries where it prevents fibers from sticking to process equipment which can cause quality problems and result in expensive downtime and cleaning.
- ETFE Tefzel® Coating
- Tefzel® ETFE has excellent chemical resistance & can be applied as thick as PFA but is the tougher. It is often used to coat the interior surfaces of stainless steel fume exhaust ducts as it is a tough polymer that can withstand rough handling during installation. Its strong adhesion also allows for field modifications such as various taps or cutting ducts to specific lengths.
- Multi-coat blend
- A two or three coat system of PTFE, FEP, & PFA Teflon® to optimize performance in the form of superior abrasion resistance & extended service life.

Teflon® Coating Process:
- Cleaning: Parts are cleaned to remove all oil, grease & other substances. Cast parts are de-gassed.
- Pretreatment: Parts are pretreated to ensure proper adhesion.
- Material Preperation: Teflon® is rolled at 30 rpm for 30 minutes to ensure the coating has been adequately mixed.
- Application: The coating is sprayed onto the item either manually or on one our automated production lines.
- Cure / Bake: Depending on the coating used the part is cured in an oven at a temperature from 320°F to 815°F.
- Inspection: Parts are inspected to ensure proper application.
