Abstract
An adhesive composition comprising a silane-modified epoxy resin, a dicyclopentadiene novolac epoxy resin and a curing agent. The composition shows good oily steel bonding, even in the absence of CTBN rubber or rubber adducts as toughening agents, with good Tg values of the cured resin and good Tg retention after hot wet aging.
