The ABCs of fluoropolymer nano-coatings

What is a fluoropolymer coating?

A fluoropolymer coating is a material comprised of fluorocarbons and characterized by carbon-fluorine bonds.

Chemically inert, fluorocarbons are not susceptible to Van der Waals force. This means they are hydrophobic, non-stick and friction reducing.

Also, due to their fluorine bonds, fluoropolymer coatings demonstrate a high level of durability as well as resistance to acids, bases and most solvents.

What is a nano-coating?

 Nano coatings are typically applied at a few microns. Some coatings are applied at 0.25um or even less.

What are the typical properties of fluoropolymer’s?

They can include:

  • Being highly hydrophobic (water repellent)
  • Having a high moisture barrier
  • Being highly oleophobic (oil repellent)
  • Having a high chemical resistance
  • Having a high lubricity (low friction)
  • Having high dielectric properties
  • Suitable for sterilisation
  • Providing high corrosion resistance
  • Providing good abrasion / wear resistance

Note, not all of the fluoropolymer coatings have all of the above properties. But, some of the coatings can in fact have almost all of the properties.

What sectors are fluoropolymer nano-coatings being used?

Nano coatings are used in almost all industrial sectors.

They include:

  • Aviation
  • Aerospace
  • Defense
  • Automotive
  • Industrial
  • Oil & Gas
  • Electronics
  • Medical/Pharmaceutical
  • Optics
