DuPont Teflon® Coatings

Industrial products made with Teflon fluoropolymer resins have exceptional resistance to high temperatures, chemical reaction, corrosion, and stress-cracking. The properties of Teflon have allowed Precision Coatings to prevent corrosion in applications that otherwise could not be coated.

Teflon Coatings have superb release characteristics. They melt flow to smooth, nonporous films, and are thus more chemically resistant than other PTFE coatings. Teflon coatings are extremely non-wetting and have very low coefficient of friction.

Typical advantages to Teflon?

  • Teflon is a dry powdered coating process that will enhance the durability and longevity of normal steel parts. In practical tests, Teflon? has extended the life span of oil field equipment that was normally coated with thick film epoxies. The main reason being that the entire ID of the part was coated, leaving NO exposed surfaces.
  • The fluoropolymer protects threads without compromising the makeup or tolerance of the parts connections. This is not possible with fusion bonded epoxies, due to their thickness.
  • Produces smooth, even 1-4 mils of protective coating to all areas of metal parts. There are no exposed areas.
  • Teflon provides resistance to hydrogen sulfide (H2S), carbon dioxide (co2), oxygen, salt water and stimulation acids.
  • Moderate Baking temperatures ensure that the coating has an even melt flow and creates a non-porous film on the substrate.
  • Reduces Total Cost of ownership.

Technical Data & Specifications

The Teflon coating needs no introduction… “a miracle in science” manufactured by DuPont as a non-stick industrial coating. The High level of Teflon fluoropolymer in this coating enhances lubricity and has a multitude of purposes.

NON-STICK – Very few solid substances will permanently adhere to a Teflon coating. While tacky materials may show some adhesion, almost all substances release easily.

LOW COEFFICIENT OF FRICTION – The coefficient of friction is generally in the range of 0.05 to 0.20, depending on the load, sliding speed, and type of Teflon coating used.

HEAT RESISTANCE – Teflon can operate continuously at temperatures up to 300°F, and can be used for intermittent service up to 350°F with adequate ventilation.

CHEMICAL RESISTANCE – Chemical environments usually do not affect a Teflon coating. The only chemicals known to affect these coatings are molten alkali metals and highly reactive fluorinating agents.

NON-WETTING – Since Teflon finishes are both hydrophobic and oleophobic, cleanup is easier and more thorough.

UNIQUE ELECTRICAL PROPERTIES – Over a wide range of frequencies, Teflon coatings have a high dielectric strength, low dissipation factor, and high surface resistivity. Certain coatings are electroconductive enough to be used as an anti-static coating.

CRYOGENIC STABILITY – Many Teflon® coatings can withstand temperatures as low as -454°F without loss of physical properties
