Session 1: Aerospace/Defense Response to REACh
The research and development of any coating system is time consuming and fraught with failure. When success is achieved in an area as challenging as the aerospace industry demands, it is valuable to summarize and reflect on the process.
Hexavalent Chromium is a known carcinogen, repro-toxin, and mutagen. Its elimination is of high importance to the aerospace industry which has struggled to find high performing alternates. Legacy aluminum sacrificial paints have traditionally utilized hexavalent chromium to prevent corrosion and oxidation of steels. Due to the high performance nature of these coatings, work to approve alternate coatings have been difficult. Many attempts have resulted in failure.
The process of developing a novel hexavalent-chromium-free aluminum sacrificial paint will be summarized. The history, failures, and key factors will be summarized. This presentation is intended to be tandem with the Rolls-Royce presentation on the testing results of this novel coating system.
