Usage Instructions

  1. Surface Preparation: Clean the glass surface thoroughly to remove any dirt, dust, oil, or contaminants that may affect adhesion.
  2. Treatment Application:
    1. Apply the silane treatment evenly to the glass surface using a spray or dip method.
    2. Allow the treatment to dry completely before applying the adhesive or tape.
  3. Adhesive/Tape Application: Apply the 3M adhesive or tape to the treated glass surface, following the manufacturer's instructions for bonding.
  4. Curing Time: While the treatment dries quickly, allow sufficient time for the adhesive or tape to fully bond to the glass surface.

Storage and Handling

  • Store the silane treatment in a cool, dry place away from direct sunlight and sources of heat or ignition.
  • Keep the container tightly closed when not in use to prevent evaporation.
  • Follow all safety precautions and handling instructions provided by 3M.

Safety Considerations

  • Use the silane treatment in a well-ventilated area to avoid inhalation of vapors.
  • Wear appropriate personal protective equipment (PPE), such as gloves and safety glasses, when handling the treatment.
  • Refer to the product's Safety Data Sheet (SDS) for detailed safety information and handling instructions.
