Teflon™ coatings can be used on a variety of substrates including stainless steel, carbon steel, aluminum, steel alloys, brass, and magnesium, as well as non-metallics such as glass, fiberglass, some rubber, and plastics. Teflon™ coatings spray on like paint and bake to a tough, inert finish. Over the years, DuPont technology has extended the family of Teflon™ coatings to ensure a finish with the ideal combination of properties to meet the most challenging design needs.
Peratex utilizes an extensive range of Teflon™ industrial coatings including:
Teflon™ PTFE
 |
PTFE (polytetrafluoroethylene) nonstick coatings are a two-coat (primer/topcoat) system. These products have the highest operating temperature of any fluoroplastic (260°C/500°F), an extremely low coefficient of friction, good abrasion resistance, and good chemical resistance. PTFE is available only in water-based liquid form.
Industries Typically Used For:
Coefficient of Friction Static .12 – .15 Dynamic .05 – .10 Hardness 60 |
Teflon™ FEP
 |
FEP (fluorinated ethylene propylene copolymer) nonstick coatings melt and flow during baking to provide nonporous films. These Teflon™ coatings provide excellent chemical resistance. In addition to low friction, FEP coatings have excellent nonstick properties. Maximum use temperature is 204°C/400°F. FEP is available in water-based liquid and powder forms.
Industries Typically Used For:
Coefficient of Friction Static .12 – .20 Dynamic .08 – .30 Hardness 60 |
Teflon™ PFA
 |
Like FEP, PFA (perfluoroalkoxy) nonstick coatings melt and flow during baking to provide nonporous films. PFA offers the additional benefits of higher continuous use temperature (260°C/500°F), film thicknesses up to 1,000 micrometers (40 mils), and greater toughness than PTFE or FEP. This combination of properties makes PFA an excellent choice for a wide variety of uses, especially those involving chemical resistance. PFA is available in both water-based liquid and powder forms.
Industries Typically Used For:
Coefficient of Friction Static .2 Hardness 60 |
Teflon™ One Coat
 |
These solvent-based liquid coatings are formulated with special blends of fluoroplastics and other high-performance resins to improve toughness and abrasion resistance. Because the film components stratify during baking, most of the fluoroplastic properties (such as low friction and nonstick character) are retained. The resins provide adhesion and abrasion resistance. These products can sometimes be applied to smooth, clean metal. Bake requirements vary, depending on the specific coating.
