Aerospace series - Paints and varnishes - Chromate free non corrosion inhibiting two components cold curing primer for military application

This European Standard defines the requirements for a two components, chromate and lead free epoxy, non corrosion inhibiting primer. The coating should be suitable for use on fibre reinforced composite materials, titanium and corrosion resistant steels and other suitably prepared corrosion resistant substrates.

Luft- und Raumfahrt - Beschichtungsstoffe - Zweikomponenten Grundbeschichtung, chromatfrei, nicht korrosionshemmend, raumtemperaturhärtend, für militärische Anwendung

Diese Europäische Norm legt die Anforderungen an eine chromat- und bleifreie, nicht korrosionshemmende
Zweikomponenten-Epoxid-Grundbeschichtung fest.
Die Beschichtung muss für die Anwendung auf faserverstärkten Verbundstoffen, Titan und korrosionsbeständigem
Stahl und anderen geeignet hergestellten korrosionsbeständigen Substraten geeignet sein.

Série aérospatiale - Peinture et vernis - Peinture primaire sans chromate non anticorrosive à deux composants polymérisant à température ambiante pour applications militaires

Aeronavtika - Barve in laki - Brezkromatni, protikorozijski, dvokomponentni temeljni premaz, ki se strdi pri temperaturi okolja, za vojaško uporabo

Ta evropski standard določa zahteve za dvokomponentni epoksidni temeljni premaz brez kroma in svinca, ki ne preprečuje korozije. Premaz naj bi bil primeren za uporabo na kompozitih, ojačanih z vlakni, titanu in jeklih, odpornih proti koroziji, ter drugih ustrezno pripravljenih podlagah, odpornih proti koroziji.
