Applications & Uses

- Compatible Substrates & Surfaces
- Cure Method
- 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.
- Directions for Use
- 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.

then conditioned to pull temperature for 30 minutes before testing.
ES569 can withstand higher temperatures for brief periods (such as for paint baking and wave soldering processes) providing the joint is not unduly stressed.
The minimum temperature the cured adhesive can be exposed to is -40°C (-40°F) depending on the materials being bonded.- Chemical Resistance
Specimens were immersed for 30 days at 85ºC and tested at room temperature.
