The present invention relates to a one-part epoxy structural adhesive comprising an epoxy resin, a toughening agent, a reactive liquid modifier present in an amount ranging from about 5% to about 15% by weight of the structural adhesive, and a latent amine curing agent. The structural adhesive can optionally include reactive diluents, synthetic mineral fibers, fillers, pigments, and combinations thereof. Structural adhesives can be used to form bonded joints between metal parts with clean surfaces as well as metal parts with surfaces contaminated with hydrocarbon-containing materials such as oils, processing aids and lubricants. have. |
