What is Teflon® Coating?
Chemours Teflon® coatings are just one of the many industrial coatings solutions offered at Plas-Tech Coatings.
Teflon® is Chemours registered trademark for its non-stick coatings. Teflon® coatings are specially formulated finishes that are based on PTFE, PFA, FEP, and ETFE fluorocarbon resins. Teflon-S® is a related family of fluorocarbon coatings containing binding resins which provide increased hardness, abrasion resistance, and other desirable properties.
Plas-Tech Coatings is a Chemours Licensed Industrial Applicator, specializing in high-quality, cost-effective Teflon® coatings for various industrial applications. For pricing on our Teflon® coating products, or to simply learn more about them, submit a free request for quote today.
Types of Teflon® Coatings
PTFE (Polytetrafluoroethylene) nonstick coatings are typically two-coat (primer/topcoat) systems. These products have the highest operating temperature of any fluoropolymer (290° C/550° F), an extremely low coefficient of friction, good abrasion resistance, and good chemical resistance.
ETFE is a copolymer of Ethylene and Tetrafluoroethylene and is also sold under the Tefzel® trademark. Although not fully fluorinated, ETFE has excellent chemical resistance and can operate continuously at 150° C/300° F. This resin is the toughest of the fluoropolymers and can be applied as film builds up to 1,000 micrometers (40 mils) to provide a highly durable finish.
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 205° C/400° F.
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 (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.
Teflon-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 fluoropolymer properties (such as low friction and nonstick) are retained. The resins provide adhesion and abrasion resistance. These products can sometimes be applied to smooth, clean metal. Bake requirements vary, depending on the specific coating, from 165° C/325° F to 370° C/700° F.
Silverstone® is a specialty line of superior nonstick finishes produced by DuPont. Silverstone® coatings are three-coat (primer/midcoat/topcoat) systems formulated with PTFE and PFA. Characteristics of Silverstone® coatings are similar to other PTFE coatings, however, durability is greatly increased. A reinforced version with higher scratch and abrasion resistance is also available. Maximum continuous use temperature is 290° C/550° F.
