Information on Teflon Coating

Although we usually associate the word Teflon with a non stick surface, Teflon coatings actually go beyond providing a non-stick surface. In the industrial and engineering worlds, Teflon coatings are very important to machines and products because it either makes or breaks them.

There are many different types of Teflon coasting and below are some of the most common types used.

Among all the different kinds of Teflon coating, Teflon PTFE (poly tetrafluoroethylene) is the most popular of them all. Teflon PTFE is a non-stick coating that is made up of a primer and then a top coat. PTFE can handle the highest temperatures up to 500 degrees Fahrenheit among all the other types of fluoropolymers. The coefficient of friction of PTFE is very low and this is one of its other advantages. Abrasions and different kinds of chemicals can be resisted by Teflon PTFE. The only downside to Teflon PTFE is that it comes only in liquid form and is water based.

You best option if you are looking for a film that is non-porous is Teflon FEP or fluorinated ethylene propylene copolymer. During baking, this type of coating melts and flows. This Teflon coating is also resistant to commonly used chemicals and it is also the type that is very non-stick. You can get this type of Teflon in powder form and as a water based liquid.

Teflon PFA is quite similar to FEP is some ways. But PFA tolerates a higher temperature during continuous use and can reach up to 500 degrees Fahrenheit. PFA or perfluoroalkocy is also tougher that FEP or PTFE, so it can handle a lot more than the first two types of Teflon coating. PFA can also be used in powder or as water based liquid form.

Teflon also sells tefzel ETFE which is the toughest fluoropolymer available today. This type of coating is not completely fluorinated which is important in some application. This type comes only in power form.

Teflon One Coat is ideal if you are looking for a Teflon coating that is solvent based rather than water based. This type of coating has been blended and is much thought and extremely resistant to abrasions. Teflon one coat can sometimes work well with smooth metal surfaces, something which the other coatings cannot do and will need a rough surface to help it stick.

In situations that involve a lot of pressure and high velocities, Teflon Dry Lubricant is the best choice. It is like one coat in that it is solvent-based rather than water-based, and this particular coating is designed a bit differently so that it can work better under high amounts of pressure or velocity.

You can apply Teflon coatings on aluminum, steel, steel alloys, stainless steel, brass, glass, rubber, fiberglass, and even plastic.
