Fluoropolymer TEFLON® Coatings

We are a TEFLON Coatings Company. DuPont™ TEFLON® coatings are available in both powder and liquid. The versatility of TEFLON® coatings allows for almost unlimited application to a wide variety of part sizes and configurations, always adding value far beyond the inherent nonstick qualities.

TEFLON® coatings once applied are baked 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 most design needs.

By combining heat resistance with almost total chemical inertness, excellent dielectric stability, and a low coefficient of friction, TEFLON® coatings offer a balance of properties unbeatable by any other material. It is the original nonstick finish. DuPont, the originator of TEFLON®, has the worldwide resources to help you solve your coating problems.

The Basic Types of TEFLON® Coatings

DuPont™ TEFLON® industrial coatings can be used on carbon steel, aluminum, stainless steel, steel alloys, brass, and magnesium, as well as non-metallics such as glass, fiberglass, some rubber, and plastics. Optimum adhesion is obtained by roughening the surface before applying the coating. Except where specifically mentioned, most TEFLON® industrial coatings require a primer coat.

1. TEFLON® PTFE

PTFE (polytetrafluoroethylene) nonstick coatings are two-coat (primer/topcoat) systems. These products have the highest operating temperature of any fluoropolymer (260°C/500°F), an extremely low coefficient of friction, good abrasion resistance, and good chemical resistance. TEFLON® PTFE is available only in water-based liquid form.

2. TEFLON® FEP

FEP (fluorinated ethylene propylene copolymer) nonstick coatings melt and flow during baking to provide nonporous films. These coatings provide excellent chemical resistance. In addition to low friction, TEFLON® FEP coatings have excellent nonstick properties. Maximum use temperature is 204°C/400°F. TEFLON® FEP is available in water-based liquid and powder forms.

3. TEFLON® PFA

Like FEP, PFA (perfluoroalkoxy) nonstick coatings melt and flow during baking to provide nonporous films. TEFLON® 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 TEFLON® PTFE or TEFLON® FEP. This combination of properties makes TEFLON® PFA an excellent choice for a wide variety of uses, especially those involving chemical resistance. TEFLON® PFA is available in both water-based liquid and powder forms.

4. TEFZEL® ETFE

ETFE is a copolymer of ethylene and tetrafluoroethylene and is also sold under the TEFZEL® trademark. Although not fully fluorinated, TEFZEL® ETFE has excellent chemical resistance and can operate continuously at 149°C/300°F. This resin is the toughest of the fluoropolymers and can be applied at film builds up to 1,000 micrometers (40 mils) to provide a highly durable finish. TEFZEL® ETFE is available in powder form.

5. TEFLON® One Coat

These solvent-based liquid coatings are formulated with special blends of fluoropolymers and other high-performance resins to improve toughness and abrasion resistance. Because the film components stratify during baking, most of the fluoropolymer 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.

6. TEFLON® Specialty Systems

These aqueous-based dispersions are specially blended multi-coat systems of TEFLON® PTFE (polytetrafluoroethylene), TEFLON® FEP (fluorinated ethylene propylene copolymer), and TEFLON® PFA (perfluoroalkoxy) to optimize performance characteristics through material synergy. Formulations are available with internal reinforcement materials in the coating matrix to increase abrasion resistance and extend service life.

7. TEFLON® Dry Lubricant

Dry lubricant coatings are special versions of TEFLON® technology designed to provide lubrication under high-pressure/velocity (PV) conditions. These products are solvent-based, one-coat systems that are usually cured between 260°C/500°F and 371°C/700°F.
