TFE (Tetrafluoroethylene) industrial coatings can be used on carbon steel, aluminum, stainless steel, steel alloys, brass and magnesium, as well as non-metallics such as glass, fiberglass and some rubber and plastics. Haward Corporation has been applying TFE products since 1965 and has the expertise and experience to ensure optimum adhesion with every application.
PTFE (polytetrafluroethylene) nonstick coatings are two coat (primer/topcoat) systems. These products have the highest operating temperature of any fluoropolymer 550°F, an extremely low coefficient of friction, good abrasion resistance and good chemical resistance.
FEP (Fluorinated Ethylene Propylene Copolymer) nonstick coatings 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 nonstick properties. Maximum use temperature is 400°F. FEP is available in water based liquid and powder forms.
Like FEP, PFA (Perfluoroalkoxy) nonstick coatings melt and flow during baking to provide non-porous films. PFA offers the additional benefits of higher continuous use temperature 500°F, film thicknesses up to .040” 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.
ETFE is a copolymer of Ethylene and Tetrafluoroethylene, and is and is also sold under the TEFZEL® trademark. Although not fully fluorinated, ETFE has excellent chemical resistance and can operate continuously at 300°F. This resin is the toughest of the fluoropolymers and can be applied at film thicknesses of up to .040” to provide a highly durable finish. ETFE is available in powder form.
TFE-S One Coat
These solvent-based liquid coatings are formulated with special blends of fluoropolymers and other high performance resins to improve toughness and abrasion resistance. Because the film components stratify during baking, most of the fluoropolymers properties, such as low friction and nonstick characteristics are retained. The resins provide adhesion and abrasion resistance. Bake temperatures vary from 325°F to 600°F depending on the specific coating.
