Along with our customers we develop tailor – made solution for highly demanding industrial coating applications. These solutions exploit the synergy of the effects of different types of surface enhancement. To ensure your better understanding we herewith provide some examples for your perusal.

Teflon coatings are unique industrial non stick systems with properties unmatched by any other fluoropolymer coatings.

High performance teflon coatings can be used to cut production costs and increase productivity which make them ideal for an infinite variety of applications.

Teflon coatings differ from other fluoropolymer coatings in one very important aspect. They are composite materials, Lubricants with the lowest known coefficient of friction are combined with newest high temperature resistance organic polymers with following unique properties.

• Lowest coefficient of friction
  
• Excellent release & non-stick properties
  
• Non wetting – both hydrophobic & oleophobic
  
• Thermal stability over wide operating temperature range: from 400⁰F to 500⁰F
  
• Unique electrical properties such as high dielectric strength.
  
• High surface resistivity and low dissipation factor.
  

The Six Basic Types of Teflon Coatings:

1) Teflon PTFE (polytetrafluoroethylene) nonstick coatings are two-coat (primer/topcoat) systems. These product have the highest operating temperature of any fluoropolymer (2600C/5000F) and extremely low coefficient of friction, good abrasion resistance and good chemical resistance PTFE is available only in water based liquid form.

2) Teflon FEP (fluoridated ethylene propylene co-polymer) 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  2040C/4000F FEP is available in water-based liquid and powder forms.

3) Teflon PFA, Like FEP, PFA (perfluoroalkoxy) nonstick coatings melt and flow during baking to provide nonporous films PFA offers the additional benefits of higher continuous use temperature ( 2600C/5000F ) film thickness up to 1000 micrometers (40 mils), and greater toughness than PTFE or FEP. This combination of properties make 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.

4) Teflon 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  1490C/3000F. This resin is the toughest of the fluoropolymers and can be applied at film builds up to 1,000 micrometer (40 mils) to provide a highly durable finish ETFE is available in powder form.

5) Teflon S One Coat: These solvent – based liquid coatings are formulated with special blends of fluoropolymer 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. These products can sometimes be applied to smooth, clean metal. Bake requirements vary, depending on the specific coating from  1630C/3250F to 3160C/6000F

6) Teflon -S Dry Lubricant: 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  2600C/5000F and 3710C/7000F.

The coefficient of friction of teflon is generally in the range of 0.05 to 0.20 depending on the load, sliding speed, and particular Teflon coating used.

Nonstick:

Very few solid substances will permanently adhere to a Teflon coated finish. Although tacky materials may show some adhesion, almost all substances release easily.
 
Non Wetting:

Since surfaces coated with Teflon are both oleo phobic and hydrophobic, they are not readily wetted. Clean up is easier and more through – in many cases, surfaces are self – cleaning.

Heat Resistance:

Teflon industrial coatings can operate continuously at temperature up to 260⁰C / 500⁰F with adequate ventilation.

Unique Electrical Properties:

Over a wide range of frequencies, teflon has high dielectric strength, low dissipation factor and very high surface resistivity, By special techniques, it can even be made elctroconductive enough to be used as an anti-static coating.

Cryogenic Stability:

Many teflon industrial coatings withstand severe temperature extremes without loss of physical properties. Teflon industrial coatings may used at temperature as low as 270⁰C /-454⁰F

Chemical Resistance:

Teflon is normally unaffected by chemical environments. The only chemicals known to affect all Teflon industrial coatings are molten alkali metals and highly reactive fluorinating agents.
