Corrosion from Reclaimed Water
Can you please tell me if powder coated aluminum can hold up to reclaimed water?
Q. Can you please tell me if powder coated aluminum can hold up to reclaimed water? We use reclaimed water here in Florida for lawn irrigation and I need to know if this will hold up for mailbox post application. K.W.
A. Yes, it can hold up but there are some important qualifications. You will need a good aluminum conversion coating to create a surface that is conducive to good bonding of the coating. You will need an epoxy primer coat to provide good chemical resistance and provide good edge coverage. You will need a chemically resistant topcoat that has good UV protection. The combination of primer and topcoat should be between 3 and 6 mils. If you do it correctly it will hold up very well.
Infrared cure is gaining increased attention from coaters as a result of shorter cure cycles and the possibility of smaller floor space requirements when compared to convection oven curing.
Choosing the right conveyor system, coating technology, and ancillary equipment.
The year 2020 will be here before you know it, signaling the beginning of a new decade and bringing changes to the world as we know it.
