- Application Process
- Thaw sealed at ambient for 30 minutes before using.
- Dispense adhesive onto clean substrate.
- Pre-bake dispensed adhesive at 80°C for 30 minutes to achieve optimum bonding. Pre-bake not needed in all applications.
- Cure according to one of the recommended cure schedules.
Note:
- For higher temperature curing, above 125°C and/or bonding area of over 1x1sq cm, it is recommended the dispensed adhesive be pre-baked, open faced without parts, at 80°C for 30 minutes before parts are mounted and cured.
- 24 Hour 125°C or 100°C vacuum or air flow oven post bake required to meet outgassing requirements
