Directions for use

Post Activation

  1. Apply Loctite cyanoacrylate to the parts to be bonded or
  2. Apply Activator over all exposed cyanoacrylate adhesive
    by spray or drop. (Typically use one drop of activator per
    drop of exposed adhesive).

Surface Activation

  1. Apply one coating of Activator to the area to be bonded by
    spray, brush or dipping. Contaminated surfaces may need
    special cleaning or degreasing prior to activation to
    remove any soluble contamination.
  2. Allow LOCTITE® SF 7109™ to fully evaporate from parts
    prior to bonding to avoid solvent entrapment within the
    bond joint.
  3. Apply the Loctite cyanoacrylate product immediately after
    drying or not more than 45- seconds thereafter.
  4. Activator can be re-applied if necessary if there is a delay
    of more than 45- seconds between original activator and
    adhesive application.
  5. Due to physical solvency effects material may become
    cloudy which does not affect performance. To eliminate
    cloudiness heat material to 30C, then shake.
