COLOMIERS, France – PPG has qualified its proprietary AEROCRON™ electrocoat (e-coat) aerospace primer at Dassault Aviation for application to structural aircraft parts for corrosion resistance. Qualification to DGT153703 enables Dassault subcontractors to produce parts for the aircraft manufacturer using the chrome-free PPG e-coat primer.
According to Daniel Bencun, PPG Segment Manager for Aerospace Coatings in the Europe, Middle East and Africa region, the Dassault qualification demonstrates growing interest in the advantages of PPG’s e-coat primer.
“Throughout its history, Dassault has been an innovator and aviation industry leader, and qualifying Aerocron primer shows Dassault’s continued commitment to technological advancements and the environment,” Bencun said. “In addition to its many application and performance benefits, Aerocron primer is chrome-free and water-based, and it reduces emissions as well as waste-treatment requirements.”
“Dassault aircraft operators will benefit from the reduced weight of coated parts and superior corrosion resistance with Aerocron primer,” Bencun said. “While it is difficult to spray on a primer with a consistent coating thickness, Aerocron primer achieves a uniform thickness even on hidden and recessed areas of a part, a significant advantage important within the aerospace industry. Weight savings can be about 30% for flat parts and up to 75% on complex-shaped parts.”
PPG expects qualifications by other original-equipment aircraft manufacturers and tier-one suppliers soon, Bencun said.
Aerocron primer is also qualified to SAE International’s Aerospace Material Specification 3144 for anodic electrodeposition primer for aircraft applications.
