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?
Thanks,
John D

There are two primary reasons to coat an object – to protect and to beautify. The inclusion of color into a formula satisfies the latter objective. Before delving into the particulars of pigmentation, a few definitions are in order. Colorant pigments are sometimes referred to as prime or opacifying pigments.

When comparing two samples with the same pigmentation, but different degrees of gloss, the one with the higher degree of gloss is visually perceived as darker and more saturated than the matte sample. For this reason, it is very important to measure both surface effects separately.
