When the U.S. Occupational Safety and Health Administration (OSHA) implemented stringent permissible exposure limits for hexavalent chromium in early 2006, the goals seemed impossible. Achieving the same or higher levels of performance with chrome-free technologies, particularly in the aerospace industry, simply didn’t appear feasible. The hurdles were too great. The costs were too high. The finishing industry collectively groaned, “We can’t.” OSHA set the bar and said, “Try it.” And guess what - we’ve come a long way.
