Two chromate-free products from PPG Industries’ aerospace coatings group, a metal pretreatment and an exterior decorative primer, are now standard on Boeing Next-Generation 737 production airplanes. Desogel EAP-9 metal pretreatment and Desoprime CF/CA 7502 epoxy primer can be used with virtually any qualified topcoats.

According to PPG, the primer is the only chromate-free primer on Boeing’s qualified product list for its BMS 10-72 (revision Y) exterior decorative paint specification, and airlines also are requesting the product with a non-chromated pretreatment for Boeing 767 and 777 widebodies.
