LOCTITE ECCOBOND E 1216M is a black, epoxy-based composite underfill, which can handle high-volume assembly operations where fast-flow filling is required. It cures entirely in a single reflow cycle but is stable enough to be easily shipped and used in large-volume cartridges (up to 0.59 ml / 20 oz). Specifically formulated to eliminate anhydride-type curing agents.
