About DuPont Teflon® Coatings

Teflon® PTFE fluropolymer resin was first discovered in 1938 by DuPont chemist Roy Plunkett. Since that time DuPont has developed a versatile line of industrial coatings that carry the Teflon® trademark. DuPont Teflon® industrial coatings have gained acceptance in a wide range of applications. Many Teflon® coatings are FDA compliant and can be used for food contact applications.

DuPont Teflon® industrial coatings can be used on aluminum, carbon steel, stainless steel, steel alloys, brass, magnesium, and other metals, as well as on non-metallics; such as glass, fiberglass, some rubber and plastics. Optimum adhesion is obtained by roughening the surface prior to application of the coating. Thermal processing is then required to cure the coated product.

Plas-Tech serves an endless list of industries. The reason why we serve so many industries is because of the diverse characteristics of Teflon® and the other fluoropolymer coatings we apply. Did you know that in addition to having the lowest coefficient of friction of any solid material known to man, that Teflon® is non-wetting, has a high dielectric strength, almost universal chemical resistance, and in many cases is thermally resistant to 500°F.

Outstanding Properties of Teflon® Coatings

NON-STICK

Very few substances will permanently adhere to a Teflon® coated surface. While tacky materials may show some temporary adhesion, almost all substances release easily.

Teflon® coating on belts in the food industry prevents build-up of cooking residue and allows easy clean-up.

NON-WETTING

Since Teflon® surfaces are both oleophobic and hydrophobic, they are not readily wet. Clean-up is easier, more thorough and in many cases self-cleaning. Because it is non-wetting, laboratory glass ware such as beakers, test tubes, stirrers, etc., are frequently coated with Teflon® to prevent cross-contamination.

TEMPERATURE STABILITY

The combination of extreme low and extreme high temperature stability (-450°F to + 550°F) favors the use of Teflon® over a wider temperature range than any other organic coating material.

Teflon® coated extrusion dies that permit higher extrusion rates and better surface finish are an example of a high temperature application where other coatings cannot be used.

LOW COEFFICIENT OF FRICTION

The coefficient of friction of Teflon® is in the range of 0.03 - 0.15, depending on the load, sliding speed and particular Teflon® finish used.

Threaded plugs that must be removed and re-inserted frequently are coated with Teflon® for permanent lubrication to prevent galling and permit re-sealing.

CHEMICAL RESISTANCE

Teflon® is unaffected by most chemical environments. The only chemicals known to affect Teflon® finishes are certain alkali metals and most highly reactive fluorinating agents.

Metal seals coated with Teflon® show improved sealing properties because of the conformability of Teflon® Coating.

New Teflon® coating compounds have been developed that can be applied to elastomer "O" rings and seals.

UNIQUE ELECTRICAL PROPERTIES

Over a wide range of frequencies, Teflon® has high dielectric strength, a low dissipation factor, and very high surface resistivity. By special techniques, it can even be made conductive enough to be used as an anti-static coating. Strain relief straps for the computer industry are coated with Teflon® because of its high dielectric properties and attractive appearance.

RECOATABLE

In many cases, damaged or worn coatings can be removed and re-applied to original specifications. Contact us for more information on how to renew the Teflon coating on your industrial parts.
