Scope Description & guide for users A two pack Polyurethane paint System to be used for the Finishing and refinishing of Vehicles and equipment of the Australian Defence Services. Available in a flat (APAS 0154/1 and /8) or low gloss (APAS 0154/3 and /9) and at two levels of infra red reflectance; "Conventional" provides low IR reflectance for maximised camouflage effect.

3 Near Infrared Reflecting (designated "NIRR") is intended for minimised solar heat absorption. The paint systems shall be suitable for use over suitably pretreated ferrous and non-ferrous metal surfaces and also over aged Polyurethane or alkyd paintwork. The Finishing paint, when applied by spray in accordance with the manufacturers directions to a vertical surface, shall produce a film of dry thickness 20 - 30 m. (a) On Ferrous MetalsFollowing metal pretreatment by phosphating or abrasive blast cleaning, application of one coat of epoxy primer to APAS 0154/2 (conforming to the performance requirements of MIL-P-53022) or one coat of a suitable commercial multipurpose primer to APAS 0154/6, followed by one coat of the appropriate Polyurethane finish, APAS 0154/1, 3, 8 or 9.

4 (b) On Non Ferrous MetalsFollowing metal pretreatment by conversion coating or application of an etch primer to APAS 0154/5, application of a coat of epoxy primer to APAS 0154/7 (conforming to the performance requirements of MIL-P-23377) or one coat of a suitable commercial multipurpose primer to APAS 0154/6 followed by Polyurethane finish, as in above. (c) On Previously Painted SurfacesFollowing pretreatment by removing any oil or grease and by lightly abrading the previous film of aged Polyurethane or aged alkyd paint, application of Polyurethane finish, as in above.
