This standard specifies the requirements for a two component, cold curing, polyurethane, abrasion resistant coating available in a range of colours and levels of gloss, to be applied over a primer for aerospace applications. The properties specified in this standard are obtained on defined aluminium alloy test pieces prepared in accordance with EN 3837 Process A and ISO 3270 and painted with primer to prEN 2435-02. 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.
