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 said the company.

“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.

Brooks said airlines are also requesting Desoprime CF/CA 7502 primer with a non-chromated pretreatment for Boeing 767 and 777 widebodies.
