PPG Industries' aerospace coatings group has qualified AEROCRON electrocoat primer to SAE International's Aerospace Material Specification 3144 for anodic electrodeposition primer for aircraft applications.
Qualifying Aerocron primer to the aerospace industry standard provides airframe manufacturers and subcontractors with third-party verification of its performance characteristics and attributes, according to Duane Utter, PPG global coatings segment manager, military coatings and classified products.
Four variations of the PPG chromate-free primer have been qualified to AMS 3144 in order to meet specific customer or regional requirements..
Primer provides corrosion resistance to metal parts and is typically applied by spraying. In the electrocoating, or electrodeposition, process, metal parts are dipped into an electrically charged tank of Aerocron primer.
