Surface treatment and powder coating
Coating failures are rarely the powder's fault. They are usually a cleaning, rinsing or conversion problem that happened before the part reached the booth. Ganesh runs seven-tank pretreatment, a 16 ft by 16 ft shot blast chamber, an 18 ft by 14 ft powder booth, a wet paint booth and a curing oven in-house. These guides cover each tank, degreasing by substrate, phosphating, powder versus wet paint, DFT and adhesion testing, and diagnosing blistering, pinholes and creeping corrosion.
