What is a Zinc Phosphate Coating?

Comments · 8 Views


A phosphate coating is a process that will help to improve the corrosion resistance and the paint adhesion on both iron and steel. There are a few types of this coating that are available, but the best one to use is zinc. Zinc is a powerful coating that is able to hold onto some of the rust-preventing oils to make the material as strong as possible.


The process of zinc phosphating will rely on a neat chemical reaction that is then going to occur with a metal substrate when the process solution is in contact with the metal. This process is meant to create a type of crystallization, which will give you a protecting layer of that zinc to help out with this.


One of the benefits of using this is that the zinc phosphate is going to prevent the steel or iron from corroding over time. This keeps the metal strong and prevents a big issue with it fading or falling apart on you. But how is it able to complete the job?


The zinc phosphate coatings will have the ability to prevent corrosion because they provide both a corrosion protection and strong adhesion as possible. At the same time, this zinc phosphate is going to help improve some of the friction properties that is so important for any components that need to slide together in order to function.


Another thing that you may be curious about is how thick the coating will be. For all of the benefits that you can get, and all of the protection, you will find that it is going to be a light coating. It can vary based on the product you are working with but the thickness will range between .0002 and .0006 inches thick. And since it is made out of translucent crystals, the coating will often look light grey or black in coloring.


There are many industries that will use this kind of coating. It is so light while providing you with the protection that you need on a lot of metals, without making them fall apart or any of the harmful chemicals can make you sick in the process. Heavy mining equipment, pipelines, oilfield drilling, and refineries will all utilize this kind of coating.


When you have steel or iron and need to make sure that you are able to get a strong coating that will make the metal stronger while preventing corrosion The zinc phosphate coating is one of the best options that you are able to work with. Finding the right coating for any steel or iron product you want to use will help that project stay strong and last.
