Aerospace series - Paints and varnishes - Corrosion inhibiting two components cold curing primer for military application
This European Standard defines the requirements for a two components, high corrosion inhibiting epoxy
primer.
The coating shall be suitable for use on suitably prepared metallic substrates, chromic acid anodized or
conversion coated aluminium alloys, fibre reinforced composite materials and other suitably prepared
substrates.
Luft- und Raumfahrt - Beschichungsstoffe - Zweikomponenten Grundbeschichtung, korrosionshemmend, raumtemperaturhärtend, für militärische Anwendung
Diese Europäische Norm legt die Anforderungen an eine Zweikomponenten-Epoxid-Grundbeschichtung,
hoch korrosionshemmend, fest.
Die Beschichtung muss für die Anwendung auf geeignet hergestellten metallischen Substraten, mit
Chromsäure anodisierten oder mit Umwandlungsschichten versehenen Aluminiumlegierungen, faserverstärkten
Verbundstoffen und anderen geeignet hergestellten Substraten geeignet sein.

Aeronavtika - Premazna sredstva - Dvokomponentni temeljni premaz, ki se strdi na zraku, za preprečevanje korozije, za vojaško uporabo
Ta evropski standard določa zahteve za dvokomponentni epoksidni temeljni premaz, ki učinkovito preprečuje korozijo. Premaz naj bi bil primeren za uporabo na ustrezno pripravljenih kovinskih podlagah, aluminijevih zlitinah, anodiziranih s kromovo kislino, ali z reakcijsko prevleko, sestavljenih materialih, ojačanih z vlakni, in drugih ustrezno pripravljenih podlagah.
