Rust Inhibitors - Keeping Rust Out of the Finishing Process
It is no secret that rust causes rejections and failures of manufactured metal parts. The application and use of rust inhibitors is critical to reduce the cost of corrosion during the manufacturing process. A rust inhibitor is a chemical compound that decreases the corrosion rate of metal alloys. A rust inhibitor forms a thin film or passivation layer on the surface of the metal that hinders the access of the environment to the metal surface. This chemical layer retards either oxidation or reduction of the metal. The effectiveness of a rust inhibitor depends on many factors, including but not limited to concentration, environment, and time.
In the manufacturing process, rust inhibitors can be classified as "in process rust inhibitors" or "long term rust preventatives". In process rust inhibitors are designed to prevent corrosion during and between the manufacturing processes, while long term preventatives provide a shelf life of 30 days to 1 year or longer.
Precision Finishing manufactures aqueous "water based" in process inhibitors and long term preventives. The aqueous in process inhibitors are safe to use and environmentally acceptable. The inhibitors are formulated into soluble lubricants, coolants, cleaners, straight inhibitors and other processing compounds. A unique advantage of some types of in process inhibitors is the ability to coat or paint over the inhibitor without effecting adhesion. This saves you the cleaning step, which in turn, saves time and money. Many long term preventatives contain oil or oil like chemicals. Ever rising oil prices and escalating environmental costs associated with disposing of oil make using a water-based preventative extremely attractive. Water based preventatives are now available for up to 1 year shelf life.
