Teflon coating services

Chemours recognized the importance in the application procedure and expertise to engineer the appropriate application system for their Teflon coating products to perform optimally. To accomplish this they created their Licensed Industrial Applicator (LIA) program that includes approximately 20 coaters nationally. Crest has the distinction of being an LIA for more than 40 years.

Because of our experience in applying Chemours Teflon™ coatings by our skilled staff and modern equipment, Crest has been a Chemours Licensed Industrial Applicator for more than 40 years. This is a source of pride for us, and a source of confidence for our customers.

The variety of Chemours Teflon™ industrial coatings is extensive. For any particular use, there may be several Chemours Teflon™coatings that will perform well. Drawing on the experience of a Licensed Industrial Applicator ensures the best Chemours Teflon coating for a given application, whether it be PTFE®, FEP®, PFA®, ETFE®, Chemours Teflon-S™, or others.

Crest’s engineering and expertise in Teflon coating services is recognized nationwide. We can help engineer the best system for your requirement. Customers from all parts of America routinely send components to us for coating.

Specifications

Outstanding Properties of Chemours Teflon™

NONSTICK
Very few solid substances will permanently adhere to a Chemours Teflon
™ coated finish. Although tacky materials may show some adhesion, almost all substances release easily.
LOW COEFFICIENT OF FRICTION
The coefficient of friction of Chemours Teflon™ is generally in the range of 0.05 to 0.20, depending on the load, sliding speed, and particular Chemours Teflon coating used.
NONWETTING
Since surfaces coated with Chemours Teflon™ are both oleophobic and hydrophobic, they are not readily wetted. Cleanup is easier and more thorough — in many cases, surfaces are self-cleaning.
HEAT RESISTANCE
Chemours Teflon™ industrial coatings can operate continuously at temperatures up to 287°C/550°F and can be used for intermittent service up to 316°C/600°F with adequate ventilation.
UNIQUE ELECTRICAL PROPERTIES
Chemours Teflon™ has high dielectric strength, low dissipation factor, and very high surface resistivity. By special techniques, it can even be made electroconductive enough to be used as an anti-static coating.
CRYOGENIC STABILITY
Many Chemours Teflon™ industrial coatings withstand severe temperature extremes without loss of physical properties. Chemours Teflon™ industrial coatings may used at temperatures as low as -270°C/-454°F.
CHEMICAL RESISTANCE
Chemours Teflon™ is normally unaffected by chemical environments. The only chemicals known to affect all Chemours Teflon™ industrial coatings are molten alkali metals and highly reactive fluorinating agents.

Types of Chemours Teflon™ Coatings

Chemours Teflon™ PTFE Coating

Polytetrafluoroethylene nonstick coatings are two-coat or three-coat (primer/topcoat) systems. These products have the highest operating temperature of any fluoropolymer (287°C/550°F), an extremely low coefficient of friction, good abrasion resistance, and good chemical resistance. PTFE coating services are available only in water-based liquid form.

Chemours Teflon™ FEP

Fluorinated Ethylene Propylene Copolymer nonstick coatings melt and flow during baking to provide nonporous films. These coatings provide excellent chemical resistance. In addition to low friction, FEP coatings have excellent nonstick properties. Maximum use temperature is 204°C/400°F. FEP is available in water-based liquid and powder forms.

Chemours Teflon™ PFA

PFA (perfluoroalkoxy) nonstick coatings melt and flow during baking to provide nonporous 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 coating 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.

Chemours Teflon™ ETFE

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 149°C/300°F. This resin is the toughest of the fluoropolymers 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.

Chemours 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 character) are retained. The resins provide adhesion and abrasion resistance. Depending on the application, these materials may require sand blasting, etching or surface oxidation to obtain the desired results. Bake requirements vary, depending on the specific coating, from 163°C/325°F to 316°C/600°F.

Chemours Teflon-S™ Dry Lubricant

Dry lubricant coatings are special versions of Chemours Teflon™-S technology designed to provide lubrication under high-pressure/velocity (PV) conditions. These products are solvent-based, one-coat systems that are usually cured between 148°C/300°F and 371°C/700°F.
