A chromate-free metal pretreatment and a chromate-free exterior decorative primer from PPG Industries’ aerospace coatings group are now standard on Boeing Next-Generation 737 production airplanes.
Desogel EAP-9 metal pretreatment and Desoprime CF/CA 7502 epoxy primer by PPG Aerospace can be used with any qualified topcoats on Boeing Next-Generation 737 airplanes. Desoprime CF/CA 7502 primer is the only chromate-free primer on Boeing’s qualified product list for its BMS 10-72 (Revision Y) Exterior Decorative Paint specification.
“After many years of successful testing and field evaluations, Boeing has selected Desoprime CF/CA 7502 primer as standard for Boeing Next-Generation 737 production aircraft,” said Kevin Brooks, PPG Aerospace global segment manager for original-equipment coatings. “PPG shares the ongoing commitment to sustainability of Boeing and airlines, providing ‘green’ coating products that offer the necessary and desirable application, aesthetic and performance benefits.”
Brooks said airlines are also requesting Desoprime CF/CA 7502 primer with a non-chromated pretreatment for Boeing 767 and 777 widebodies.
