Perfluoroalkoxy Alkane Coating (PFA Coating)
Perfluoroalkoxy Alkane (PFA) Coating is a fluoropolymer coating based on PFA, a co-polymer product of PTFE. The co-monomer perfluoroalkyl vinyl ether interferes with crystallisability and molecular weight to achieve good mechanical properties and melt processability without sacrificing thermal performance and chemical resistance.
Perfluoroalkoxy Alkane Coating (PFA Coating)
PFA coating offers outstanding chemical resistance, even at elevated temperatures. It is resistant to strong mineral acids, inorganic bases and inorganic oxidizing agents, as well as most of the organic compounds and their mixtures commonly found in the chemical industry.
PFA coating is therefore suited to applications where chemical resistance, thermal performance and mechanical properties are important considerations.
However, PFA will react with fluorine and molten alkali.
Types of PFA Coating
Non-Antistatic PFA Coating
Colour: White / Red
Antistatic PFA Coating
Colour: Black
Usage of PFA Coating
PFA coating is used in applications where outstanding chemical resistance and thermal performance are required, including demanding environments within the chemical industry.
Its resistance to strong mineral acids, inorganic bases, inorganic oxidizing agents and most organic compounds and their mixtures makes PFA coating suitable for applications involving aggressive chemical environments, including those operating at elevated temperatures.
The availability of non-antistatic and antistatic PFA coating variants provides options according to the requirements of the application.
PFA coating can be considered where a combination of chemical resistance, mechanical properties, melt processability and thermal performance is required.
PFA Coating for Chemical-Resistant Equipment
When equipment operates in demanding chemical environments, the coating needs to withstand the specific chemical and thermal conditions of the application.
PFA coating provides outstanding chemical resistance, including at elevated temperatures, making it suitable for demanding applications involving strong mineral acids, inorganic bases, inorganic oxidizing agents and a wide range of organic compounds.
Advance Expertise Technology provides PFA coating solutions in both non-antistatic and antistatic variants for applications requiring high levels of chemical resistance and thermal performance.
