General Description

4487 is a single part epoxy based heat curing ink for application using an open cup pad printing system. It was designed specifically for printing on materials used in the manufacture of electronic components including low stress and conventional molding compounds, ceramic, anodized aluminum, nickel and gold. This ink is suitable for flash curing on in line IR systems and was formulated to provide a wider process window than typical single part inks.
