Q: Hey Joe,
I am looking at a report that a major company just sent in. The steel parts are showing signs of rust after 24 hours and visible signs of rust after 48 hours in a 5% salt fog solution.
Somewhat new to this world of powder coating – how is this possible? Some holes and slots that have been punched out I can somewhat understand. But when I see aluminum wheels and outdoor items holding up season after season I would have thought the powder coating would hold up longer?
Is there a method of correlation between hours in a salt chamber and what this means to user conditions?
Each issue, we take the padlock off the PCI® Test-Lab door for a few minutes so our favorite technical editor and “powder guru” Joe Powder can run in the yard. When he’s not gnawing on a rawhide bone, he loves to answer readers’ questions. Go ahead and send him one at firstname.lastname@example.org... he doesn’t bite. Maybe it’ll end up in the next issue!
