Abstract
Disclosed are one-component epoxy resin adhesive compositions which include (a) one or more non-rubber-modified epoxy resins; (b) one or more latent epoxy curing agents; (c) one or more toughening agents; and (d) zinc oxide nanoparticles. The one-component epoxy resin adhesive compositions exhibit improved toughness of the adhesive as measured by its lap shear strength as well as improved environmental stability, i.e., corrosion protection, by addition of the zinc oxide nanoparticles when applied to metal substrates.
