Almost every manufacturing plant that deals with ferrous and nonferrous metal needs to protect parts, components, equipment, or subassemblies from corrosion. In most metal-working plants, parts in process spend approximately 50 to 80% of the time awaiting further processing. Humidity, heat, perspiration, and airborne contaminants, as well as cutting oil and coolant residues, can attack the unprotected metal.
