Why & How Aircraft Paint Processes Are Changing
Duncan Aviation has been researching and testing “green” paint processes for nearly two years, and by 2011 all aircraft painted at Duncan Aviation’s facilities will use a FAA approved, chrome-free paint process. The company is not the first business aircraft maintenance, repair and overhaul service provider to make the transition, nor will it be the last.
For customers who have come to rely on Duncan Aviation’s quality and attention to detail, the change begs the question: why make the switch without a regulatory mandate?
Introduction
Chromate compounds have provided effective aircraft corrosion protection for almost 80 years. However, the aviation industry is beginning to trend toward the use of chrome-free alternatives.
Questions have been raised regarding the safety of using chromates and the possibility of environmental hazards. Regulatory requirements have become far more stringent, and the cost of compliance is prohibitive. Chrome-free paint systems have been developed that present an effective, safe and more environmentally responsible alternative.
When properly applied, these paint systems are comparable—if not superior—to their older, chromate counterparts. Adhesion is improved, coating failures are reduced and performance meets or exceeds testing standards. They have been adopted by the United States Air Force, several major commercial airlines and some business aircraft manufacturers and service providers.
Although chrome-free paint systems provide effective corrosion protection for aircraft, proper application is critical. Vigilance is key when assessing a paint proposal and evaluating the experience and capabilities of a service provider.
This document provides an assessment of market drivers, product performance, application processes and considerations for selecting a service provider.
