| Résumé : |
Until recently heavy metal based corrosion inhibitors were widely accepted as the only materials that could provide the corrosion protection needed. Corrosion inhibitors provide an indispensable function to protective coatings. The performance of a coating under corrosive conditions requires that corrosion inhibitors provide sustainable protection during the coatings warranty. The coating industry however is challenged to be more cognizant of the impact toxic metals have on human health and the environment. In response to the European Directive 1999/45/EC Advancement of Technical Progress (ATP) amendment 29 effective October 2005, products containing zinc oxide and zinc phosphate required hazardous label ing due to their marine toxicity. The growing pressure to replace zinc, barium, strontium and other heavy metals has shifted the coatings pendulum to more ecofriendly alternatives. This paper captures specific products reflecting the new paradigm of technologies based on heavy-metal free inorganic pigments as well as non-toxic organic corrosion inhibitors. |
