Document Type and Number:
WIPO Patent Application WO/2010/011710
Kind Code:
A3
Abstract:
A two-part epoxy-based structural adhesive composition comprising a curable epoxy resin, an amine curing agent, a toughening agent, and an oil-displacing agent. The structural adhesive may optionally include reactive liquid modifiers, fillers, secondary curatives, reactive diluents, surfactants, metal salts, pigments and combinations thereof. The structural adhesive may be used to form bonded joints between adherends having clean surfaces, as well as those having surfaces contaminated with hydrocarbon-containing materials, such as oils, processing aids and lubricating agents.
