Introduction
This standard has been prepared in accordance with TR 7000-9.
1 Scope
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.
