Aerospace series - Paints and varnishes - Two component cold curing polyurethane coating - Abrasion resistant

This standard specifies the requirements for a two component polyurethane, abrasion resistant coating available in a range of colours and levels of gloss, to be applied over a primer for aerospace applications offering resistance to wear on sliding surfaces and resistance to impact from solid particles.
The properties specified in this standard are obtained on defined aluminium alloy test pieces prepared in accordance with EN 3837 Procedure A and ISO 3270 and painted with primer to EN 2435. The ability of the material to be used for a specific application (e.g. alternative substrate, alternative primer, specific drying conditions etc.) shall be determined by supplementary tests to confirm that the requirements of this standard are met.

Luft- und Raumfahrt - Beschichtungsstoffe - Zweikomponenten-Polyurethan-Deckbeschichtung, kalthärtend - Abriebfest

Diese Norm legt die Anforderungen an eine kalthärtende, abriebfeste Zweikomponenten Polyurethan Deck¬beschichtung fest, die in einer Reihe von Farben und Glanzstufen vorkommt und die in der Luft- und Raum¬fahrt über einem Primer aufgetragen werden soll, um Abriebfestigkeit auf glatten Oberflächen und Schlag¬festigkeit gegen feste Partikel zu bieten.
Die in dieser Norm festgelegten Eigenschaften werden anhand definierter Probenkörper aus Aluminiumlegie¬rung ermittelt, die nach EN 3837, Verfahren A, und ISO 3270 vorbereitet und mit einem Primer nach EN 2435 beschichtet werden. Die Eignung des für eine bestimmte Anwendung zu verwendenden Materials (z. B. alter¬nativer Trägerwerkstoff, alternativer Primer, bestimmte Trocknungsbedingungen usw.) ist durch zusätzliche Prüfungen bestimmen, um nachzuweisen, dass die Anforderungen dieser Norm erfüllt werden.
