PERMABOND® ES578
- Chemical Family
- Epoxy & Epoxy Derivatives
PERMABOND® ES578 is a single-part heat cured epoxy adhesive with excellent adhesion to metal surfaces, ceramics as well as composite materials. ES578 provides excellent thermal conductivity and bond strength. ES578 was designed for applications requiring heat dissipation such as bonding aluminum heat sinks to ceramic headers.

- Ready-to-Use Products
- Use Direction
The adhesive should be dispensed from the bottle via the nozzle supplied (this can be cut to give the appropriate sized bead to cover the bond area).; Apply the adhesive to one surface and avoid entrapping air.; Assemble parts applying sufficient pressure to ensure the adhesive spreads to cover the entire bond area.; Use a jig / clamp to prevent parts moving during cure.; It is advisable not to disturb the joint until the adhesive is fully cured.; Cure with heat – see page one for cure schedule.
- Benefits and Features
- Very good thermal conductivity
- Excellent resistance to vibration
- Easy to use – no mixing required
- High shear and peel strength
- High temperature resistance
- Good resistance to chemicals
- Electrically insulating
- Storage Temperature
- 2 to 7°C (35 to 45°F)
- Surface Preparation
Surfaces should be clean, dry and grease-free before applying the adhesive. Use a suitable solvent (such as acetone or isopropanol) for the degreasing of surfaces. Some metals such as aluminum, copper and its alloys will benefit from light abrasion with emery cloth (or similar), to remove the oxide layer.
