FEP Coating


FEP (Fluorinated Ethylene Propylene copolymer) coatings melt and flow during baking to provide smooth non-stick, non-porous films with excellent abrasion resistance. Because the coating is non-porous its chemical resistance is superb. FEP coatings can withstand a maximum use temperature of 205°C (400°F) continuously and intermittently up to 450°F. These coatings are chemically inert to most chemicals and solvents except very strong alkali solutions and fluorine at elevated temperatures. This coating is typically applied to a thickness of 1-5 mils DFT. FEP coatings are available in both water-based and powder forms for many application methods.
