Permeation—Its Effects on Teflon® Fluoropolymer Coatings

Fluoropolymers are virtually inert substances that can withstand high temperatures. These two properties make them ideal for use as coatings to protect metals from corrosive attack. It is important to realize that fluoropolymer coatings are used where other polymers could not possibly survive, that is, under extremely hostile conditions. Under such conditions, permeation assumes a much more important role in the determination of performance.
