“My application is spraying clear powder on to a plated surface. There is less than 1 mil of plating thickness. Will the nominal cure temp (350 – 400 DEG F) induce discoloration of the substrate for “Unstable Finishes” such as brass and bronze? “

“Depending upon what salts and soils are left on the surface and the rate of temperature rise on the part during curing, the simple answer is yes. Polished brass surfaces have successfully been powder coated after great care has been taken to ensure that the surface is completely clean and neutralized and the curing temperature is gradually induced into the part using convection heating techniques.”
