Different Types of Teflon Coating
It is almost always that when you say Teflon, people will immediately think of “nonstick”. On the other hand, Teflon coating has gone beyond offering people with 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 an abbreviation for poly tetrafluoroethylene and one of the most popular options too. Such nonstick coating does consist of primer as well as top coat. Out of all fluoropolymers that can be bought in the market, the PTFEs are capable of handling even the most extreme temperatures that reaches up to 500 degrees Fahrenheit.
Another great benefit of using PTFE is that, it has low coefficient or friction. It is very resistant as well to abrasions and other kinds of 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 – for this specific kind of Teflon coating, it is actually similar with FEP in some ways but, it withstands higher temperature even on continuous usage. PFA or perfluoroalkoxy can handle more than what PTFE or FPE can do, which makes it extremely tough. And almost the same with FEP, it is also available in water based liquid and powder.
Tefzel ETFE – no doubt, this is the strongest and the toughest available fluoropolymer on the market. This coating is not actually fluorinated which is essential 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 kind of coating is blended and very tough and works great in resisting abrasions. Also, it works best on smooth metal surfaces, which is another advantage it has.
Teflon dry lubricant – oftentimes, you will be glad of using dry lubricate when the process involves high velocities and pressure. Like the One Coat, this is also solvent based however, the difference is that, the coatings follows different design process. It is for this exact reason why they are capable of having peak performance even under on high amounts of velocity or pressure without compromises.
