Surface Preparation

  • Ensure all bonding surfaces are clean, dry, and free from dust, grease, and oil.
  • Trials are recommended to confirm if additional surface cleaning is required.

Mixing & Application

  1. Screw the static mixer onto the cartridge.
  2. Dispense adhesive until a uniform grey colour is observed.
  3. Apply Fasto E400 to all engaged bonding areas.
  4. Assemble parts immediately.
  5. Wipe off excess adhesive from outside the joint.

Curing Guidelines

  • Fixture time: ~20 minutes
  • Strength build-up:
    • ~40% strength in 30 minutes
    • ~70% strength in 3 hours
    • 100% strength in 24 hours
  • Maximum gap: 0.5 mm
