Abstract:
A new "green" exterior aircraft painting system in development by PPG Industries' (NYSE:PPG) aerospace coatings business has shown corrosion resistance comparable to processes using chromated pretreatment and primers as well as easier application than for alternative environmentally responsible systems.

PPG Aerospace ‘Green’ Paint System Inhibits Corrosion, Promotes Adhesion

Sylmar, CA | Posted on April 2nd, 2009

The PPG Aerospace chromate-free depaint/repaint process includes a new exterior epoxy primer based on nanotechnology and an adhesion promoter PPG manufactures under license from Boeing, according to Alan Schoeder, PPG Aerospace commercial coatings global segment manager.

"In salt spray and filiform corrosion testing, metal surfaces protected by new Desoprime HS CA 7502 high-solids exterior epoxy primer showed the same corrosion resistance as those coated with chromated primers," Schoeder said. The PPG Aerospace environmentally-responsible primer is expected to be qualified this year at Boeing, he added.

Eldorado Adhesion Promoter (EAP-9) uses Boeing's proven Boegel technology that PPG has licensed, Schoeder said, enabling PPG to offer airframe manufacturers and third-party painters an easy-to-use, competitively-priced conversion coating.

"EAP-9 is applied to the stripped aluminum airframe and allowed to dry, and then Desoprime HS CA 7502 primer is applied," Schoeder said. "With a chromated process, the chemical has to be rinsed off, putting hazardous material into the rinse water. Unlike another chromate-free conversion coating, only one application is needed with EAP-9, and no mechanical abrading is required."

When EAP-9 is used with Eldorado corrosion remover and brightener EAC-8, resulting metal-corrosion resistance is similar to resistance achieved through processes using chromated chemicals, Schoeder said.

"PPG Aerospace will be offering a complete, easy-to-apply, green depaint/repaint coatings system that meets the rigors of the exterior aerospace environment," Schoeder said.

PPG Aerospace is the aerospace products and services business of PPG Industries. PPG Aerospace - PRC-DeSoto is the leading global producer and distributor of aerospace coatings, sealants, and packaging and application systems. PPG Aerospace - Transparencies is the world's largest supplier of aircraft windshields, windows and canopies.
