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 aluminium, copper and its alloys will benefit from light abrasion with emery cloth (or similar), to remove the oxide layer.

Directions of Use

  • Surfaces must be clean, dry and grease-free prior to bonding.
  • Shake cartridge (or stir bulk material) before use if separation has occurred.
  • Apply a thin bead of adhesive pre-mixed through a static mixer nozzle. (Alternatively bulk material can be dispensed via metered dispensing equipment).
  • Assemble components and clamp.
  • Maintain pressure until handling strength is achieved.
