In most cases, consumers will leave it up to the industrial coating services that they use to properly apply PTFE coatings. If that’s the case, however, then there are a some questions they should be asking.
Not every industrial coating services professional performs the PTFE coating process correctly, and it’s up to the consumer to determine whether or not a company is reputable enough to do just that. To ensure that every industrial coating service is applying PTFE powder coating or spray coating appropriately, here are three things the consumer should be checking for.
Proper Surface Preparation
Just as a painter and their canvas, an industrial coating service must have properly prepared surfaces for their coatings to adhere properly. This includes both cleaning and roughening the substrate surface to be coated. First, the surface must be thoroughly cleaned, and then roughened by chemical etching, which allows the coating to “bite” into the surface and stick to it indefinitely. This process results in a strengthened bond between the coating and its surface, and should be performed with applied medical coatings and other coatings as well.
Dry Film Thickness
Dry film thickness (DFT) provides vital information pertaining to the expected life of the substance, the product’s fitness for purpose, its appearance, and ensures compliance with a long list of International Standards. This is perhaps one of the most important steps in the process and should be done without error. If a coating is applied too thickly, problems such as mud-cracking, sagging or blisters can occur. If too thinly, hazing or low gloss will be apparent.
Proper Cure
The last part of the coating process is providing a proper cure for the coating. Curing the bonds between coating and surface is done by heating to 425 degrees Celcius for about 10 minutes for PTFE coatings.
These three elements are absolutely essential for a successful and long lasting coating. Before a consumer gets anywhere with an industrial coating service, the company should be able to attest to these three key elements in their coating process. Read more blogs like this.
