Why Is Thickness Important In Powder Coating?

Powder coating is one of the most popular techniques for imparting a great look to the surfaces of metallic objects. Although there were traditional methods of coating the substances with paint and other materials, nothing could beat the finish provided by the powder coating. Even the experts are claiming that powder coating is the most effective technique that can help you in achieving metal finishing. Powder coating is in demand for yet another reason, and that is it can be applied to almost all products. This shows that the powder coating technique is highly versatile and efficient. Besides this, the overall finishing touch credit also goes to the technicians who are skilled enough and have the right knowledge to make the performance better. Moreover, they will ensure that the powder coating thickness is perfect — nothing less or more. This thickness of the powder coat layer is the most crucial thing that will let you know whether the end result would be good or not. The technicians or the workers make use of state-of-the-art techniques in order to impart high precision and quality while applying the powder coat.

Why Do You Think The Thickness Of the Powder Coat Surface Is So Important?

There are several reasons that will help you understand why the thickness of the powder coat is important. But first of all, you need to recognize that the help of consistent and regular measurement of the thickness of the powder coat, will help you to have control over the cost of the powder coat and also keep a check on the efficiency level of the application.

During the inspection phase, the thickness of the powder coat is one of the most essential aspects that would be considered to verify the perfection of the layer.

According to the experts, it is revealed that the overall appearance, as well as the performance of the finished product, is entirely dependent on the thickness of the coat which is technically known as the “Dry Film Thickness” — DFT.

DFT or Dry Film Thickness influence a lot of factors of the substance that achieves powder coat — the DFT can have an impact on the adhesion, color, surface finish (matte effect or gloss effect), texture, and resistance to corrosion as well as the toughness of the coat. Thus DFT or the thickness of the powder coat is so important.

The thickness of the powder coat that is being applied on the surface of the substance is not something the technicians can choose to have. It has to be based on the specifications laid out by the ISO — International Organization for Standardization. During an inspection, it has to be ensured that the thickness of the powder coat is well maintained. This perfect work performed by the coat specifiers, thickness inspectors, and technicians is what makes the final finish worthy and of the best quality. So the dry film thickness or thickness of the powder coat is extremely crucial and must not be neglected if you want the substance to stand out from others. If the required thickness is not met, then the process needs to be followed again. Powder coaters have to cross check the thickness and quality of the layer. They need to do this stringently to prevent the wastage of both money and time.

How Will You Determine The Thickness Of The Powder Coating?

Any substance that is being powder coated must have a thickness ranging from 2 mils to 8 mils. During the process of powder coat, when the powder is sprayed on the surface of the substance, the technicians ensure that the thickness of the coat is maintained evenly — which is not very thick nor very thin. They will measure the thickness of the layer or the coat before and after the application to ensure that the layer is uniform and does not exceed the specified range.

The technicians make use of the ultrasonic instruments, which are used in measuring the thickness, and if there is an extra coat, then it would be easy to remove the extra powder automatically.

Post-cure thickness measurement is as important as pre-cure thickness measurement. It entails that the product would have a high-quality finish and sleek look.

Summary

Powder coating is definitely in demand but this is because the thickness of the powder coat is well maintained. This perfect work performed by the coat specifiers, thickness inspectors, and technicians is what makes the final finish worthy and of the best quality. So the dry film thickness or thickness of the powder coat is extremely crucial and must not be neglected if you want the substance to stand out from others.
