Can we use powder painting after phosphating? Our manufacturer says that we cannot paint after phosphating. Since after phosphating, surface of parts are oily. Thus parts cannot be painted after phosphating.
Is this true?

Hi, Guven. Phosphating before painting is the quality approach, and is almost universal. You can and should do it -- but immediately before painting. I think the confusion stems from the fact that phosphatizing can also be applied as an oil retention coating for other purposes.
