PTFE coating your equipment is one of the best ways to save money on wear and tear.

Helping to make your equipment heat resistant, chemical resistant, reduce friction and increasing electrical resistance, the applications for PTFE coating are numerous and help to save businesses huge amounts of money over the long run.

This guide explains the coating procedure from start to finish, as performed by our expert engineers.

 

WHAT IS PTFE?

PTFE stands for PolyTetraFluoroEthylene and is more commonly known under various brand names such as Teflon™ and Xylan®.

PTFE coatings offer excellent non-stick properties for a variety of different applications such as bakeware equipment and release coatings.  The application of a non-stick coating that is tailored to the needs of your specific business and internal processes means your equipment will last longer, your business will save money and the quality of your end product can be improved.

PTFE remains effective at temperatures of up to 290°C/550°F and also has excellent chemical resistance which makes it one of the most effective and durable coatings around.

WHAT KIND OF APPLICATIONS IS PTFE USED FOR?

PTFE is perhaps most valued for its low friction, non-stick and high heat resistance which make it perfect for specific needs, from state-of-the-art machinery to simple pans and trays for bakers.

While many individuals will have a piece of kitchenware designed as ‘non-stick’ using PTFE, it is also used for sliding parts to avoid a build-up of friction in machinery, and as a dry lubricant. 

As PTFE can increase the service life of the equipment it is applied to, it is renowned as being a very cost effective solution.

 

Preparing equipment for coating

It is important to prepare the surface of any material to be coated in PTFE. This step helps to ensure the best coating possible and further extends the service life of the equipment to be coated. All parts will be specially blast cleaned in order to prepare for the coating process.

When the surface has been prepared it is time to apply the coating.

There are a number of different ways that PTFE can be applied and AFT Fluorotec Coatings will work with you to determine the correct solution for your requirements.

 

SPRAYING

In a simple spray system, the coating is fed into a spray gun which regulates the expulsion of the fluid into a smooth, steady stream by forcing the liquid into small droplets, much in the same way as a can of spray paint.

This ensures an even coating and a smooth finish.

This is the simplest method and is usually the most effective as it often provides the best coating, gives a smooth overall finish, can be used for awkwardly-shaped objects and requires less specialist equipment and special safety procedures.

 

ELECTROSTATIC COATING

Electrostatic coating works in a similar method to conventional spraying but uses a modified spray gun which negatively charges the droplets with an electrode. Since the piece of equipment to be coated is left electrically neutral, this means that the droplets stick much more closely to the surface they are being applied to until the coating is finished, making it a more efficient way of operating and even saving on coating which can otherwise miss the surface.

On the downside, equipment with complex shapes can sometimes suffer from the coating not being able to fully penetrate certain areas, since the electrical attraction often means the coating will stick to the sides of areas rather than penetrating fully down into recesses. In addition, this process also poses significant safety risks, requiring all equipment and materials to be well grounded and extra precautions to be taken against electric shocks and build-up of static electricity. Additional protective clothing must also be worn to guard against electrical shocks.

Experienced PTFE users, such as our engineers at Fluorotec, are well versed in both kinds of coating, and will have an extensive knowledge on which type of application should be used in which situation to get the best possible results for you and your equipment. We have developed our knowledge of PTFE over many years of providing great solutions for our customers, and always know the best way to get the job done as quickly and smoothly as possible.


AFTER COATING

After PTFE coatings have been applied they are oven baked to dry out and final cure the finish with a varying thickness depending on the required specifications of the coating and the equipment.

Our skilled and experienced engineers at Fluorotec can decide on the best PTFE Coating process for your needs and get the job done as quickly and efficiently as possible. As well as our excellent rates providing a cost effective solution, you’ll also find that PTFE coating saves a huge amount of money in the long run.
