The New Generation of Rust Preventative Products Based on Renewable Materials and Incorporating Vapor phase Corrosion Inhibitors

Corrosion protection was always the important part of industrial development.  The use of oil- and solvent-based products in the preservation of metal has been a common practice for over one hundred years.  While these products may offer good corrosion protection, they often contain hazardous ingredients and are non-degradable.  A number of regulations were implemented recently for the protection of the environment.  The most known among them are North Sea (UK, Norway, Denmark, The Netherlands) and US Gulf Coast lists of the chemicals environmentally acceptable in these regions, limiting the number of chemicals allowed for use in accordance with their level of biodegradability, bioaccumulation and toxicity.

Recently, the use of vegetable oils and their esters has been found to offer many similar properties to their petroleum derived counterparts.  By incorporating Vapor phase Corrosion Inhibitors (VpCIs) in different naturally derived solvents, optimal corrosion protection or other desired performances can be obtained yielding environmentally friendly, biodegradable products.

The laboratory test results and industrial applications of these products will be discussed in this paper.
