Abstract: Methods of applying a bond primer composition to a metal surface of an aerospace part are provided which may comprise forming a multilayer bond primer structure by (a) applying a first sublayer of a bond primer composition onto a metal surface of an aerospace part using a foam applicator comprising the bond primer composition; (b) heating the first sublayer; (c) applying a second sublayer of the bond primer composition onto the first sublayer; (d) heating the second sublayer; (e) applying a final sublayer of the bond primer composition onto an underlying sublayer of the multilayer bond primer structure; and curing the multilayer bond primer structure to form a bond primer coating adhered to the metal surface.

Abstract: A fire extinguishing system including a fluid storage container configured to store a fire extinguishing agent, and a fluid stream separating device coupled to the fluid storage container, where the fire extinguishing agent passes from the fluid storage container through the fluid stream separating device so that the fluid stream separating device raises a temperature of at least a portion of the fire extinguishing agent flowing through the fluid stream separating device above a boiling point of the fire extinguishing agent at ambient environmental conditions of a discharge location of the fluid stream separating device.
