What is Teflon Coating?

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.

 

Teflon™ Coatings — Six Basic Types

1. Teflon™ PTFE

PTFE (polytetrafluoroethylene) nonstick coatings are two-coat (primer/topcoat) systems. These products have the highest operating temperature of any fluoroplastic (260°C/500°F), an extremely low coefficient of friction, good abrasion resistance, and good chemical resistance. 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 Teflon™ coatings provide excellent chemical resistance. In addition to low friction, FEP coatings have excellent nonstick properties. Maximum use temperature is 204°C/400°F. 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. 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 PTFE or FEP. This combination of properties makes PFA an excellent choice for a wide variety of uses, especially those involving chemical resistance. 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, ETFE has excellent chemical resistance and can operate continuously at 149°C/300°F. This resin is the toughest of the fluoroplastics and can be applied at film builds up to 1,000 micrometers (40 mils) to provide a highly durable finish. ETFE is available in powder form.

 

5. Teflon™ One Coat

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

  • Associated with Steel tubes for over 10 years. During this time they Supplied various types of steel fasteners to us even sometime in very short notice, but this time we were required custom Hex bolts in Hastelloy c276 material in maximum 10 day here in Germany, i knew that it was next to impossibe, but i appriciate that they made it possible & deliverd exactly as per our drawing in 8 days, they are superb as a hastelloy hex bolts Manufacturers, They have experienced & Good team as well excellent logistic access.
