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
