Product innovation aimed at making the aerospace industry more sustainable has resulted in the launch of a new chromate-free exterior primer developed by AkzoNobel and Airbus.

Newly qualified by Airbus and now included in the aircraft manufacturer’s specifications, Aerodur HS 2121 is part of AkzoNobel’s latest generation decorative and selectively strippable system for aircraft exteriors. In addition to being free from chromates, the new primer provides users with numerous performance, appearance and application benefits.

Designed to be applied at the final assembly stage to virtually all external aircraft surfaces, it offers increased adhesion without pre-treatment (also on rivets), improved corrosion performance and flexibility, and better visual coverage. It also has enhanced wetting properties, which means less primer needs to be applied, saving time and improving efficiency.

“The launch of Aerodur HS 2121 builds on our long-standing commitment to improving our products, meeting customer needs and offering more sustainable solutions,” explains Maud Khelstovsky, AkzoNobel’s Key Account Manager for Airbus. “It’s an eco-premium solution which enables us to reduce the cost of ownership for our customers while boosting their sustainability profile.”

Adds John Griffin, Managing Director of AkzoNobel’s Aerospace Coatings business: “We’re driven by innovation and are excited to offer customers a next generation product which has clear performance and sustainability benefits. It continues our proud track record of developing market-leading solutions and going beyond expectations to provide world class functionality, performance, efficiency and value.”
