PFA (Perfluoroalkoxy alkane) coatings are high-performance fluoropolymer coatings known for their excellent chemical resistance, thermal stability, and non-stick properties. They are similar to PTFE (Teflon^®) but offer improved toughness and flexibility.

PFA coatings can provide a low co-efficient of friction or slipperiness (0.10 kinetic), non-stick, chemically inert, with excellent dielectric strength (2000V/mil) and have a high operating temperature (500°F).

PFA Coatings  are used in high-temperature environments where absolute resistance and impermeability is required. Used in industrial, chemical, and food processing equipment, non-stick PFA coatings excel in high chemical resistance, non-adhesion, and health safety even at high temperatures. PFA coatings are extensively used on chemical vessels, piping systems, mixers, reactors, and many other devices and are available in liquid and powder form.

PFA offer similar properties to that of FEP but is considered more of a premium resin. PFA coating is ideal when extended services are required in hostile environments involving chemical, thermal and mechanical stress.

Ruby Red^® PFA Coating from Chemours has a special filler which improves permeance resistance of chemical compared to regular PFA coating hence it gives a better life.

PFA coating is not degraded by systems that are commonly encountered in chemical processes. It is inert to strong mineral acids, inorganic bases, inorganic oxidizing agents, salty solutions including some organic compounds as organic acids, anhydrides, aromatics, aliphatic hydrocarbons, alcohols, aldehydes, esters, ethers, chlorocarbons, fluorocarbons and some combinations of the above.

PFA coatings that are applied on carbon steel or stainless steel have a continuous service temperature ranging between -60℉ to 400℉. A primer is compulsory before applying the PFA coating. There is a little bit of draw back for PFA coatings, if ones damaged, they cannot be repaired. Heat is required to cure the coating.
