Abstract: The present disclosure provides a thermosettable structural adhesive composition comprising an epoxy compound; a thermoplastic compound; an epoxy curing agent; non-spherical particles. This composition can be useful for applications, for example, in the form of an adhesive film. Such applications can include bonding of parts (e.g., metal parts), especially those where bonding on an industrial scale is required. The structural adhesive composition may exhibit any one or more of advantageous adhesive strength, a certain resistance to corrosion, as well as a favourable cohesive failure mode.
