Abstract
Epoxy adhesive compositions containing a rubber-modified epoxy resin contain a bisphenol. The bisphenol can be pre-reacted with the rubber-modified epoxy resin to advance the resin. The adhesives are resistant to thermal degradation as can occur in so-called 'overbake' conditions, in which the adhesive is heated to high temperatures for prolonged periods of time. In addition, expanded microballoons are included in epoxy structural adhesives to promote a desired fracture mode.
