Teflon Coating

One of the first things that come to our mind when we think about Teflon coatings are the non-sticky utensils that often are coated with Teflon coatings. Apart from utensils, Teflon also has an industrial application such as for the pharma industries, food industries, and other industries. It is also used for coating products and equipment of different sizes ranging from objects that are both humungous or minute in nature.     

Teflon was originally discovered as a Polytetrafluorethylene PTFE fluoropolymer resin by a DuPont chemist Roy Plunket in 1938. It was synthesized later in 1940, making it a compound that does not occur naturally. Teflon is nothing but a synthesized polymer that has many general uses. It comes with a variety of coating options that include size variations and thickness options. Not only this, Teflon comes with a lot of properties such as non-stickiness, low coefficient of friction, chemical inertness, and resistance that makes Teflon coating a worth have for organizations to enhance their products with the unique finish and the durability that lasts for years.   

Our process of coating involves a series of steps that we have developed over time to ensure that you get the quality that you deserve. It involves prebaking the substrate at high temperatures that makes sure that oils are removed from the coating and that there are little to none irregularities in the coating. Clean substrates ensure that the coatings adhere that is why prebaking is an important step of the process. Post the process of prebaking, aluminum oxide is grit blasted on the substrate, making it ready for coating by making them free of rust, corrosion, and any previously applied coatings. Aluminum oxide allows the surface to enlarge, making more room for the coating. It also helps by cutting through previous coatings. The next step is to spray the substrate with a preferred fluoropolymer. Manual spraying allows for precision that is required in every coat. Post Fluoropolymer spraying, the substrate is cured under high temperatures that can go up to 400°C depending on the specifications of the substrate. After the curing, it is put to quality checking to ensure that you get the quality that we have promised.    

Teflon coatings offer a range of advantages to the products that they are coated on. That Is how they also increase their value significantly. The following are the properties that they transfer

Nonsticky

The property of non-stickiness offered by Teflon coatings makes them a viable coating for many products. Most of the solid substances don’t stick to Teflon-coated surfaces.

Low Coefficient of Friction

The coefficient of friction range of Teflon coatings range between 0.05 to 0.20 depending on load, sliding speed and particular fluoropolymer, meaning less sliding force.

Heat Resistant

They provide the quality of heat resistance, allowing them to operate at temperatures as high as 290°C and 315°C with sufficient ventilation.

Nonwetting

Teflon coatings do not get easily wet making cleaning an easier task. This might be why they are also called “self-cleaning” coatings.
