We are phosphating metal parts to apply an ahesive and primer. I cant give to much info. Is the pH of the phosphate an issue? We are ok with the concentration, but we are thinking its the metal of the parts. can that be the case? The tops of the parts are fine, but the bottoms are being over phosphated. I am thinking it has to do with the rinse being too hot and the spray not working. Could this be the case?
