We took two pieces samples of PPGI from big-end brand and mid-end band respectively.
The two samples were tested together with the powder coated steel.As shown below,the paint coating surface from high-end brand was faded and foamed seriously.
The paint coating surface from mid-end brand was faded and even peeled off.This caesd the substrate material was exposed and corroded.
While the surface of powder coating steel was basically unaffected.
Why is the surface of powder coating steel basically unaffected?
The reason should be attributed to the excellent compactness of powder paint.
When the coating surface was observed under high power microscope, there were many holes on the surface of PPGI, while the surface of the powder coated steel was smooth.This avoids the penetration of water molecules, oxygen and corrosive substances from the paint coating in the air.
We can provide forming and slitting service according to clients's requests.
Slitting width:Min 5mm
