How to Formulate "Eco-Friendly" Anticorrosive Coatings

SpecialChem / Nov 5, 2008

Currently, the challenges faced by the coatings industry are not just to reduce costs and improve performance but also to fulfill strict legal requirements. The so-called "Eco-Friendly" anticorrosive coatings used to contain high or even 100% solids (like powder coatings), have low or zero VOCs. They do not contain reportable compounds, are green-label compliant (United States feature) and, in Europe, following the Directive 2004/73/CE, are non toxic for the aquatic media. Therefore, to avoid any danger to the aquatic media, "eco-friendly corrosion inhibitors" should not contain heavy metals, non reportable compounds or ingredients, and be green-label compliant and also zinc free. As a matter of fact, most of the current eco-friendly corrosion inhibitors are already heavy metal and zinc free. They are also green-label compliant and non toxic for the aquatic media. However, they show poor earlier corrosion protection and poor accelerated corrosion testing performance. Furthermore, in order to show good real world performance they have to be modified to enhance corrosion resistance.
