| Nanoparticle-Based Corrosion Inhibitors for Chromate-free Aerospace Coatings | ||
| Jeannine Elliott and Ronald Cook, TDA Research, Inc. Although chromates are very effective corrosion inhibitors, they are know carcinogens and subject to increasing regulations, including 2006 OSHA rules that dramatically reduce chromate exposure limits. Full compliance with OSHAs reduced exposure limits is required by 2010, heightening the ongoing need for eliminating chromates. TDA Research, Inc has developed novel chromate-free corrosion inhibitors for use in aerospace coatings. This nanoparticle based corrosion inhibitors has a smart release mechanism that delivers the inhibitor locally where corrosion is occurring. The corrosion inhibitor additive works by a patented design where the corrosion inhibitor is triggered to release by the corrosion process itself. This smart corrosion protection mechanism provides effective long-term corrosion protection without the use of chromate corrosion inhibitors. This additive is a powerful alternative to the toxic hexavalent chromate inhibitors that have been sued for decades. In partnership with Akzo Nobel Aerospace coatings, TDA is developing new chromate-free coatings with excellent corrosion protection. | ||
