Description

Chemours (formerly DuPont) is the manufacturer of Teflon® (Polytetrafluoroethylene / PTFE) Industrial Coatings. With a unique combination of properties, Teflon® industrial coatings have gained acceptance in a wide range of applications. They spray on like paint and bake to a tough, inert finish. Over the years, DuPont/Chemours 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® industrial coatings offer a balance of properties unbeatable by any other material. It is the original non-stick finish.

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® coatings for industrial use require a primer coat.

Outstanding Properties

Thanks to a variety of coating types, the unique properties of Teflon® industrial coatings can become an integral surface component on any kind of part — from clutches that engage easier and valves that resist wear, to coil springs that become silent. With proper equipment, Teflon® industrial coatings can even be applied to specific areas of complex geometric parts, such as the internal threads of a nut.

Nonstick Very few solid substances will permanently adhere to a Teflon® finish. Although tacky materials may show some adhesion, almost all substances release easily.
Low Coefficient of Friction The coefficient of friction of Teflon® coatings is generally in the range of 0.05 to 0.20, depending on the load, sliding speed, and the particular Teflon® coating used.
Nonwetting Since surfaces coated with Teflon® are both oleophobic and hydrophobic, they are not readily wetted. Cleanup is easier and more thorough — in many cases, surfaces are self-cleaning.
Heat Resistance Teflon® industrial coatings can operate continuously at temperatures up to 260°C (500°F).
Cryogenic Stability Many Teflon® industrial coatings withstand severe temperature extremes without loss of physical properties and may be used at temperatures as low as -270°C (-454°F).
Unique Electrical Properties Over a wide range of frequencies, Teflon® coatings have high dielectric strength, low dissipation factor, and very high surface resistivity. By special techniques, they can even be made electroconductive enough to be used as an anti-static coating.
Chemical Resistance Teflon® coatings are normally unaffected by chemical environments. The only chemicals known to affect all Teflon® industrial coatings are molten alkali metals and highly reactive fluorinating agents.
