What is Degassing?

What is Degassing?

Degassing is a crucial but often missed step in powder coating. Without it, your metal work can fall victim to outgassing, which is what happens during the curing phase when trapped gasses are released from under the zinc coating, resulting in an unpleasant finish. Not only will degassing prevent your metal work from looking unprofessional, but it also protects it from corrosion.

So, how is degassing caused, and is it as important as it sounds? Keep reading our article to learn everything you need to know about degassing, and how you can use it to prevent outgassing from ruining your metalwork.

Drying

Powder coating does not work like the paint you get from a shop. It can’t be left to dry naturally, so it needs to be put in specialized ovens for a set amount of time, depending on the size and thickness of the metal. These ovens heat the metal at 150 – 230 degrees C, depending on specifications, removing any moisture or gasses that are hidden underneath the surface.

At NSP Coatings, we use ovens that are specifically designed for the degassing process. They’re large, 8 meters long and 4 meters wide, enough to fit even the most awkwardly shaped items, and they reach temperatures which are high enough to remove any gasses which might cause damage to your steel.

Hot Zinc Spraying the Right Way

We appreciate fine metalwork. Every step of the process takes intricacy. If a single part of the process is missed or done incorrectly (like degassing), then it can ruin the whole product and spoil the finish.

This is why we take pride in every step of the powder coating process. From shot blasting to spraying your metals with hot zinc to drying and outgassing them, we take care of every step to ensure your products look professional and have a long lifespan once they’re exposed to the environment.
