Coating

PTFE (Polytetrafluoroethylene)

non-stick coating are two-coat (primer/topcoat) systems. These products have the highest operating temperature of any fluoropolymer (260°C/500°F), an extremely low coefficient of friction, good abrasion resistance and good chemical resistance. PTFE is available only in water-based liquid form.

FEP (Fluorinated Ethylene Propylene Copolymer)

non-stick coating melt and flow during baking to provide non-porous films. These coatings provide excellent chemical resistance. In addition to low friction, FEP coatings have excellent non-stick properties. Maximum use temperature is 205°C/400°F. FEP is available in water-based liquid and powder forms.

PFA

Like FEP, PFA (Perfluoroalkoxy) nonstick coatings melt and flow during baking to provide non-porous films. PFA offers the additional benefits of maximum use temperature (260°C/500°F), film thicknesses up to 1,000 micrometers (40 mils) and greater toughness than PTFE or FEP. This combination of properties makes PFA an excellent choice for a wide variety of uses. Especially those involving chemical resistance. PFA is available in both water-based liquid and powder forms.
