Installation Guide

Step 1: Clean the Surface

  • Remove dust, oil, grease, and contaminants from the bonding area.
  • Ensure the surface is clean and completely dry.

Step 2: Apply 3M K500

  • Apply a thin, uniform layer of adhesion promoter to the bonding surface.
  • Avoid excessive coating, which may affect adhesive performance.

Step 3: Allow Drying

  • Allow the treated surface to dry completely before applying adhesive tape.
  • Drying time depends on temperature, humidity, and application conditions.

Step 4: Apply Adhesive Tape

  • Apply tape with firm and consistent pressure.
  • Ensure complete contact between adhesive and treated surface.

Step 5: Allow Bond Development

  • Allow sufficient time for the adhesive bond to reach full strength before applying loads.

Storage

  • Store in the original sealed container.
  • Keep in a cool and dry environment.
  • Avoid direct sunlight and extreme temperatures.
  • Keep container tightly closed when not in use.
  • Follow recommended shelf-life requirements.
