ABSTRACT:
In an epoxy resin composition comprising an epoxy resin, a curing agent, and an inorganic filler, there are blended a salt of trimellitic anhydride with 1,8-diazabicyclo(5.4.0)undecene-7 as a curing accelerator and a mercapto-containing silane coupling agent. The composition is shelf stable and smoothly flowing and cures into a product having improved adhesion, moisture resistance and electrical properties. The composition is suitable for the encapsulation of semiconductor devices.
