Fluoropolymer coatings are blends of high performance resins and fluoropolymer lubricants. These coatings provide excellent corrosion and chemical resistance. Other benefits of fluoropolymer coatings include reduced friction, resistance to galling, non stick, non wetting, electrical resistance and abrasion resistance. Fluoropolymer coatings are applied to fasteners and various OEM components to provide a longer life before replacement.
Advantages of Fluoropolymer Coatings
1. Chemical Resistance
2. Electrical Properties
3. Heat Resistance
4. High Weather Resistance
5. Non-flammability/Safety
PFA coating is virtually inert to chemicals even at elevated temperatures and pressures. They are not attacked by inorganic basis, strong mineral acids and inorganic oxidizing agents commonly used in the chemical industry. Moreover, they are not subject to chemical attack and will not demonstrate particle generation over time. PFA (perfluoroalkoxy) nonstick coating melt and flow during baking to provide nonporous films. PFA offers the additional benefits of higher continuous use temperature 260° C/500° F, film thickness up to 40 mils, and greater toughness than PTFE or FEP. This combination of properties makes PFA an excellent choice for a wide variety of uses Specific applications include protective coatings for pumps, valves, pipes scrubbing towers, reactors and heat exchangers.
6. Non-stick
