Powder Coating Clinic: Discoloration of Metal-Flake in Powder
Q. We have a metal-flake silver powder color that we use regularly. If the surface is abraded with a Taber wheel—or even a pencil eraser—it darkens significantly in the abraded area. We even have this problem when our parts scrape against cardboard packaging. Our supplier suggested we switch from an unbonded leafing aluminum to a more expensive bonded product. We tried the bonded leafing aluminum, but we still have the same problem. Certain types of friction create this effect, seemingly those that perhaps have a higher coefficient of friction. Do they remove the aluminum flake from the surface? Can you explain this problem and tell us why it happens with some abrasives and not with others? What can we do to stop this?

Powder Coating Clinic: Sanding for Repair
Q. We sand aluminum die-cast parts that have minor defects in the powder coating before recoating them. The small areas of dirt, metal blemishes, fibers or similar particles are sanded using 120-grit sandpaper on an orbital sander. After recoating the parts, we often find more little specks and other defects and lines from the sanding disk in the coating. My question is, does this happen because of the sandpaper we are using, or because we sand all the way to the aluminum, exposing the surface and causing it to outgas?
