The Need For Special Rust Prevention Solutions For Marine Environments


Rusting is a common phenomenon, but with marine environments, this problem is intensified. Salt water plays havoc by acting as catalysts to the process of corrosion. Therefore, the need of the hour is rust prevention methods that successfully remove rust and prevent the phenomenon of rusting. Methods for rust prevention include galvanizing, powder coating and use of rust resistant alloys. Galvanization is the process of coating a metal with another metal like zinc or cadmium. The major disadvantage of galvanization is the inability of the method to provide long term rust prevention. After a period of time cracks and chips begin to develop, especially in seams and joints. Painting and coating with anti-rust products help in rust prevention by establishing a barrier which protects the metal from the environmental elements that cause corrosion. Rust resistant alloys are not strong enough to withstand pressure and thus find limited use.

Rust inhibitors are chemically produced substances that provide effective rust prevention for a long period of time. Most rust inhibitors contain high levels of VOC (Volatile organic compounds) which are toxic and harm the environment.
