LOCTITE® ECCOBOND E 1216M
Features and Benefits
Fast-flowing and void-free epoxy underfill with excellent adhesion and strength for high-volume assembly operations.
If you’re looking for an underfill that can handle high-volume assembly operations where fast-flow filling is required, LOCTITE® ECCOBOND E 1216M is a great pick. Our ECCOBOND E 1216M composite 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 / 20oz). This black, epoxy-based underfill is ideal for those who prefer to work with anhydride-free products, as it’s specifically formulated to eliminate anhydride-type curing agents.
- Void-free
- Retains stability during shipping, storage, and use
- Snap-curing
- High glass transition temperature (Tg)
