EPO-TEK H20E is a two component, 100% solids silver-filled epoxy system for chip/electronic bonding in microelectronic and optoelectronic as well as SEM mounting applications. Used extensively for themal management applications due to its high thermal conductivity.

EPO-TEK H20E features high thermal conductivity, and is very well suited for extensive high temperature applications (300-400?C)
Extremly reliable conductive adhesive choice for new and old applications
H20E contains no solvents and will not outgas
When cured, H20E is resistant to solvents, resin and moisture
Long Pot life (2.5 days)
Shelf life is one year when store at 23?C
