Q: Is powdercoating better than paint on automotive products?


The paint on your car is known as a 2K catalyzed paint. This means that before the paint is applied an activator is mixed into the paint. The catalyzed paint will actually change its chemical make up and cure, making it resistant to solvents. While a catalyzed paint is much stronger than aerosol paints it still does not compare to powder.

Once powder fully cures it’s much harder than traditional paint, making it much more scratch and chip resistant. There’s a reason almost all high-end custom cars have powder-coated frames!

When prepped and applied correctly, powder does an incredible job of preventing corrosion because of how strong it is. When a painted surface is scratched it is much more likely to go down to bare metal. At that point corrosion will begin and start to spread.

Traditional paint guns atomize the liquid paint into the air while a powder coating gun uses air to propel the powder towards the part. As the powder is leaving the gun a slight charge is added to the powder. The powder sticks to the grounded part because the powder has a slight charge when it leaves the gun and it’s then attracted to the grounded part.

Unlike liquid paints that are sprayed, there aren’t any may health threats to being in the same room without a mask on. Powder coating does not even require the use of a typical carbon filter mask, just a simple dust mask to keep from directly inhaling the powder when spraying. Because powder is heavier than atomized paint, overspray will fall on the ground right around the part and won’t float in the air for extended periods of time.
