Performance Testing

We powder coat thicker gauges of steel (10-gauge to ¼-inch plate), using a blast operation for some of the heavier parts. We want to test the parts to confirm proper pretreatment coating performance before shipment, but we have some problems with impact and conical mandrel bend testing. The aggressive reaction of the washer chemistry can cause flash rust or other problems on the lightweight panels needed for the bend tests. Is there some way to create a bend test for our heavier materials? How can we confirm that our pretreatment and powder are working correctly?

Powder Touchup

Our powder booths have an automatic application area followed by two manual touch-up stations. We have ongoing problems with light coating in areas of the parts, requiring manual touch-up. Areas around welds, seams and inside corners do not get the required coverage, and we have to use spray touch-up paint or recoat the parts. How can we do a better job in these areas?

Streaks in Coating

We apply a medium-gloss gray powder on our parts at around 3 to 4 mils thickness. Sometimes our operators leave streaks on the parts when they apply the powder, and some areas are darker than others before cure and clearly visible after cure. What is causing the streaks, and how can we fix the problem so we do not get them?
