Importance of Rust Inhibitors

Rusting or corrosion of metals occurs when moisture is present in the air and reacts with the metal surface to form metal oxides, commonly known as rust. Rusting or corrosion leads to the degradation of the metal. Metals especially iron and steel are used for building boilers, aircrafts, automobiles, ships and for a whole lot of other purposes, because of their high tensile strength. Corrosion of metals leads to the breakdown of the structural integrity of the machines and equipment, and this may cause hazards in the long run. Since, no other material has been invented or discovered that is stronger and resistant to corrosion when compared to the commonly used metals, the need for good quality rust inhibitors becomes crucial.

Traditional methods like coating metals with oil or grease, applying paint, electroplating and galvanizing help prevent corrosion but fail as long term solutions. Thus, conventional methods of preventing corrosion are not very reliable. Rust or corrosion inhibitors are compounds which greatly reduce the rate of corrosion. A good rust inhibitor should have characteristics like smooth finish, ability to provide protection from chemical attacks and should do away with the need for time consuming surface preparation.
