Teflon™ Six Basic Types Of Coatings

1. 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. 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. 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. 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. 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. 

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.

DYKOR®

 

Dykor is the brand name for our thick film dispersions, otherwise known as “thick-film” linings. In fact, builds of up to 25 mils (625 microns) can be achieved.

Dykor coatings were specifically formulated to help protect metal from hostile environments, particularly storage vessels. Because of its unique properties, Dykor is unaffected by most chemicals and solvents, has superb abrasion resistance and mechanical strength. Some less well known properties are its high thermal stability, ability to self-extinguish, high dielectric strength, and excellent resistance to weathering, UV rays and nuclear radiation. It may be interesting to note that instruments coated with Dykor can be autoclaved as well.

Dykor can be used as a single-film coating or as a topcoat in the Dykor 

XYLAN®

 

Xylan has long been the benchmark of our line of industrial coatings. Registered in most countries around the world, Xylan is used to identify our low-friction, wear-resistant composites of fluoropolymers and reinforcing binder resins.

They are first and foremost dry-film lubricants; however, they have many desirable secondary properties. These lubricants are combined in a matrix with the newest high-temperature organic polymers resulting in “plastic alloys” formulated to provide unique and desirable properties. They can “work” under heavy loads, at high temperatures, in chemical and corrosive environments, and combinations thereof. In the industrial world, they are known as “extreme performance coatings.”

Ten reasons why you should use Xylan coatings:

  1. Low friction: CoF as low as 0.02.
  2. Wear resistance: even under extreme pressures.
  3. Corrosion and chemical resistance in most environments.
  4. Weather resistance: against sunlight, salt water and road chemicals.
  5. Wide temperature operating range: from -420° to +550°F (-250° to 285°C).
  6. Flexible curing schedule: ambient to 750°F (400°C).
  7. Wide color range: color-code your product.
  8. Pliability: Many Xylan coatings will bend freely and repeatedly without breaking.
  9. Machinability: apply multiple coats of Xylan coating (most formulations) and mill to specification.
  10. Excellent adhesion: to most metals, plastics, ceramics, wood. Even to itself (most formulations).
