Abstract
A two-component epoxy-based adhesive comprising a resin component and a curing agent. The resin component comprises an epoxy resin, a polymer polyol, and fumed silica. The curing agent comprises a polyoxyalkyleneamine, an amine terminated butadiene-acrylonitrile polymer, tris(2,4,6-dimethlaminomethyl)phenol, polyamide resin, silane and fumed silica. The adhesive composition is particular useful for bonding of metals, plastics and composites and for functions such as laminating, honeycomb bonding, automotive assembly and construction assembly.
