    Abstract - (Show below) - (Hide below)

    This standard specifies the requirements for a two component polyurethane, topcoat, with a medium degree ofresistance to erosion by the effects of rain, available in a range of colours and levels of gloss, to be appliedover a primer for aerospace applications on areas where rain erosion at supersonic speeds may be a probleme.g. leading edges and air intakes.The properties specified in this standard are obtained on defined aluminium alloy test pieces prepared inaccordance with EN 3837 Procedure A and EN 23270 and painted with primer to EN 2435. The ability of thematerial to be used for a specific application (e.g. alternative substrate, alternative primer, specific dryingconditions etc.) shall be determined by supplementary tests to confirm that the requirements of this standardare met.
