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.

Abstract: Provided is a curative part usable in a two-part curable composition. The curative part includes a liquid amine; a heterogeneous dispersant; and core-shell rubber particles having an elastomeric core and a (meth)acrylic shell. The core-shell rubber particles and the heterogeneous dispersant can be collectively shear-dispersed in the liquid amine such that the core-shell rubber particles are substantially non-aggregated and the curative part is phase-stable over a period of at least 3 months at ambient temperature. Advantageously, large amounts of core-shell rubber particles can thus be incorporated into a cured resin matrix, which can afford significantly enhanced impact performance.
