Teflon Coatings - Outstanding Properties

Thanks to a variety of coating types, the unique properties of Chemours™ 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.

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® is generally in the range of 0.05 to 0.20, depending on the load, sliding speed, and particular Teflon® coating used.

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.

Unique Electrical Properties
Over a wide range of frequencies, Teflon® has high dielectric strength, low dissipation factor, and very high surface resistivity. By special techniques, it can even be made electroconductive enough to be used as an anti-static coating.

Cryogenic Stability
Many Teflon® industrial coatings withstand severe temperature extremes without loss of physical properties. Teflon® industrial costings may used at temperatures as low as -270°C/-454°F.

Chemical Resistance
Teflon® is normally unaffected by chemical environments. The only chemicals known to affect all Teflon® industrial coatings are molten alkali metals and highly reactive fluorinating agents.
