Teflon™ coatings are available in both powder and liquid. The versatility of these Teflon™ coatings allows for almost unlimited application to a wide variety of part sizes and configurations, always adding value far beyond the inherent non-stick qualities.
Teflon™ is sprayed on like paint and bakes to a tough, inert finish. Over the years, Teflon coatings have been extended to ensure a finish with the ideal combination of properties to meet most design needs.
Types of Teflon™ Coatings:
Teflon™ coatings can be used on carbon steel, aluminium, stainless steel, steel alloys, brass, and magnesium.
Teflon™ PTFE Coatings – PTFE (PolyTetraFluoroEthylene) non-stick coatings are two-coat (primer/topcoat) systems. These products have the highest operating temperature of any fluoroplastic (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.
Teflon™ FEP Coatings – FEP (Fluorinated Ethylene Propylene copolymer) non-stick coatings melt and flow during baking to provide non-porous films. These Teflon™ coatings provide excellent chemical resistance. In addition to low friction, FEP coatings have excellent non-stick properties. Maximum use temperature is 204°C/400°F. FEP is available in water-based liquid and powder forms.
Teflon™ PFA Coatings – Like FEP, PFA (PerFluoroAlkoxy) non-stick coatings melt and flow during baking to provide non-porous films. PFA offers the additional benefits of higher continuous use temperature (260°C/500°F), film thicknesses up to 10 mils and greater toughness than PTFE or FEP. PFA is available in both water-based liquid and powder forms.
Teflon™ ETFE Coatings – ETFE is a copolymer of Ethylene and TetraFluoroEthylene and is also sold under the Tefzel® trademark. Although not fully fluorinated, it has excellent chemical resistance and can operate continuously at 149°C/300°F. This resin is the toughest of the fluoroplastics and can be applied at film builds up to 1,000 micrometers (40 mils) to provide a highly durable finish. ETFE is available in powder form.
Teflon™ One Coat – These solvent-based liquid coatings are formulated with special blends of fluoroplastics and other high-performance resins to improve toughness and abrasion resistance. Because the film components stratify during baking, most of the fluoroplastic properties (such as low friction and non-stick character) are retained. The resins provide adhesion and abrasion resistance.
Teflon™ Dry Lubricant Coatings – Dry lubricant coatings are special versions of Teflon™ technology designed to provide lubrication under high-pressure/velocity (PV) conditions. These products are solvent-based, one-coat systems that are usually cured between 260°C/500°F and 371°C/700°F.
