Teflon™ Coating
Teflon™ coating services are available in both powder and liquid form
Teflon Coating Technology (Spray/Powder)
Teflon™ industrial coatings are available in powder and spray forms and they have a wide range of properties based on differing fluoropolymer chemistries. This makes Teflon™ industrial coatings suitable for use across many industries and applications.
Teflon™ coating is applied using an electrostatic powder gun or HVLP spray gun. Surface preparation is critical. Using a sandblasting process we are able to ensure a clean and well-etched surface for Teflon™ to adhere to.
Once applied Teflon™ coatings are baked at medium to high temperatures to allow the coatings to cure resulting in a tough, inert finish. The versatility of Teflon™ coatings allows for almost unlimited applications.
The Facts: What it is
Teflon™ Coating Properties
A Teflon™ coating will release most materials it comes into contact with and is used within the food, paper, packing and moulding industries for this reason. Some of the advantages are reduced down time in cleaning and increased quality and product output. Commonly coated parts are heat-sealing bars, cutting blades, baking trays and moulds. Teflon™ coatings are US and/or EU food contact approved.
As well as being used as a non-stick, Teflon™ coatings can be used as a dry lubricant on mating surfaces. In this instance, Teflon™ allows for a clean, oil-free environment and reduces mechanical wear. Used in the automotive, aerospace and military industries, example applications include hinges, rails, pistons, gears, seals, threads bearing heavy loads, and cutting blades.

The History of Teflon® Coatings
Teflon™ is simply the brand name for non-stick coatings manufactured by the DuPont Co.
It is a Polytetrafluoroethylene or as we more commonly know it PTFE.
The history of Teflon™ is perhaps well-known. It all began as a happy scientific accident. Teflon™ was mistakenly discovered by American chemist Roy Plunkett in 1938 whilst he was working in the laboratories of E.I. du Pont de Nemours and Company. Dr. Roy J. Plunkett was experimenting with Freon™ brand refrigerants in 1938 when he observed that under intense cold and pressure, the gas turned into a white, waxy solid. TetraFluoroEthylene (TFE) had polymerized inside a cylinder to give PolyTetraFluoroEthylene (PTFE). This was the world’s first fluoropolymer.
Following the discovery of the non-stick product the company went on to register and trademark it in 1945 and soon formed a partnership with General Motors. This strategic partnership resulted in them producing 900 tons of Teflon™ per year with one of its uses being in the Manhattan Project. Here General Motors used Teflon™ coatings to be applied to valves, seals and pipes that contained harmful chemicals.
The use of Teflon™ evolved when in 1954 it was applied to a saucepan by French engineer Marc Grégoire. He went on to successfully create the first Teflon-coated, non-stick pans under the brand which has now become a household name: Tefal. Cookware is now commonly associated with the application of Teflon™ but over time other sectors, including the aerospace, automotive, petrochemical and electrical industries, have come to recognise how its unique properties can benefit their processes.
As technologies have developed more PTFE-based formulas have come to market and so a wide range of PTFE products are now available outside of the brand name Teflon™.
Teflon™ Coating Manufacturers
In addition to PTFE, the Teflon™ trade name also includes FEP and PFA.
The manufacturer of Teflon™, Chemours, continues to develop new formulations and innovative applications. Chemours also have the brand Tefzel™ for their ETFE coating.
Marcote applies Teflon™ coatings on their own and with our plasma coatings to achieve enhanced or alternative properties.
There are other fluoropolymer coating manufacturers with the Xylan® range being the most well known.
The difference between Teflon™ and Xylan® lies in different formulations of specific coatings. Also, while Chemours supplies basic fluoropolymer materials or coatings made from those materials, PPG Industries, who manufacture the Xylan® brand, only supply the coatings.
