Different Types of Teflon Coating
The phrase Teflon has been associated with the word “nonstick”. On the other hand, you should know that Teflon coating isn’t just intended for providing a nonstick surface. But if it will be used in engineering and industrial world, then the ability of Teflon coating is going to be different for it is capable of making a product or machine effective or not. In fact, there are different types of coatings that can be bought and here are some of them.
Teflon PTFE – this is probably one of the popular options which mean poly tetrafluoroethylene. This nonstick coating has a primer as well as top coat. Of all the fluoropolymers that are out in the market, the PTFEs handle even extreme temperatures that can reach all the way to 500 degrees Fahrenheit.
Yet another reason for using PTFE is its low coefficient of friction. Furthermore, this has great resistance to abrasions and other chemicals.
Teflon FEP – now, if you are in search for a nonporous film, then FEP or otherwise known as fluorinated ethylene propylene copolymer is your best bet. On the baking process, this type of coating melts and thus, it flows. FEP is additionally resistant to most of the commonly used chemicals and it is very powerful and effective nonstick coating. Not just that, it comes in water-based liquid and powder.
Teflon PFA – this kind of Teflon coating is similar with FEP in some ways but it could withstand higher temperature throughout the continuous use. PFA or perfluoroalkoxy is actually better compared to PTFE or FPE so it can handle more than the first two types of coating. And almost the same with FEP, it is also available in water based liquid and powder.
Tefzel ETFE – without a doubt, this is the toughest and strongest fluoropolymer on the market. This said coating isn’t totally fluorinated which is vital in other applications.
Teflon one coat – in the event that you are in search for a Teflon coating that’s solvent based than water based, then the One Coat may be the one that you need. This coating works flawlessly in resisting abrasions as it is blended and very tough. Also, it works best on smooth metal surfaces, which is another advantage it has.
Teflon dry lubricant – in times that is involving high velocities and pressure, dry lubricate is typically the best option. Just like One Coat, this is solvent based but the coatings goes through different design process. For this reason, they can perform better even under high amounts of velocity or pressure.
