WHAT IS TEFLON® COATING?

Its most well-known brand name is Teflon®, established by the DuPont Company.Teflon® is the trademark of the Polytetrafluoroethylene (PTFE) is a syntheticfluoropolymer of tetrafluoroethylene that has numerous applications.

 

It was discovered by Roy J. Plunkett from Du Pont in 1938 and commercially launched in 1946. It is athermoplastic fluoropolymer.

 

The molecular structure consisting of a long and straight carbon chainsaturated with fluorine atoms has very inert properties due to the strong bonds between the atoms.

 

Resistant to heat, chemicals, moisture, electrical jump (dielectric) and friction, Teflon® does not stickto any material; its friction coefficient is smaller than that of all solid objects.

 

Teflon® begins to deteriorate at temperatures above 260 ° C; It completely deforms around 350 ° C.An empty pan left on the fire can exceed these degrees, but the small amount of oil burned in thepan creates a greater health problem.

WHAT ARE THE MAIN FEATURES OF TEFLON® AND NON-STICK COATING?

The main features to be considered in the next step of the coating process are;

 Non-stick: Easy to clean surface due to its structural properties.

 Low Coefficient of Friction: Depending on the pressure, friction rate and Teflon® type used, itgenerally has a coefficient of friction of 0.05 and 0.20. Provides dry lubrication.

 Non-wettability: Teflon® coated surfaces are moisture-proof, corrosion-resistant, moisture-proof and thus always clean and easily cleaned.

 High Temperature Resistance: It can work between 180-315 ° C. Insulation: Electrically proof, can also be used as anti-static coating.

 Not Affected by Negative Temperatures: It can operate up to 270 ° C without problems.

 Chemical Resistance and Stainless: Teflon® is unchanged against chemicals. Not affected byacids. Only alkaline metals and highly reactive flour materials can damage Teflon®.

APPLICATION AREAS

Teflon® coating has a wide range of applications and Teflon® coating products are available in everyaspect of our lives. Here are the areas where Teflon® coating is applied;

 Bakery and Cake Molds

 Oven Trays, Professional Cooking Group

 Small Electrical Appliances

 Energy and Construction

 Automotive Industry

 Medical Industry

 Decorative Applications

 White Goods, Defense, Aviation and Railway Industry

 Other Industries

WHICH SURFACES ARE SUITABLE FOR TEFLON® COATING?

Fluoropolymer (Teflon®) can be coated from 10 microns to 1000 microns depending on the workingconditions and conditions. Covering areas vary. These are; metal surfaces and non-metal surfaces.Metal surfaces; iron and iron alloy surfaces, stainless steel, aluminum etc. casting surfaces, whilenon-metal surfaces; glass, plastic and ceramics.
