Due to the increasing demands for less environmentally harmful products the replacement of chromate containing pigments from primers, currently in use for aerospace applications, becomes necessary more and more. Eight years ago a research project was started towards a primer development aiming at a complete chromate-free corrosion protection for the exterior of civil and military aircraft. The Aviox CF primer is an example of a proper design between a binder system and selection of corrosion inhibitor. This product performs at the same level as currently chromate-containing products, both in accelerated corrosion tests and in practice. The first airplane with the Aviox chromate-free system was recently stripped after 6 years of service life and inspected for corrosion. It was concluded that the performance of the system was at least at the same level as a conventional system comprising Cr-containing washprimer, intermediate primer and topcoat.
