The increasing complexity of modern aircraft has resulted in more rapid development of the surface coatings required. Rockhard two-pack epoxies protect fuel pump diaphragms on the Harrier and also serve as primers on some of the composite plastic structures used on the same aircraft. Often used in conjunction with epoxy primers are Indestructible's modern high performance acrylic or polyester based polyurethane finishes. These materials are well suited to modern aircraft construction materials. Based on a more recent technology are the inorganic materials now used internally on jet engines. Ipcote 9183 is used on turbine blades operating at temperatures between 500 deg C and 600 deg C. The paint film can either be processed after application up to 540 deg C or processed to 350 deg C and then vibro-polished. Another product used on various aero engines including the Harrier AV8B is a two-pack graphite attrition compound. This material is applied to the inside of engine casings to provide a seal between the casing and turbine blades.
