Installation Guide

Step 1: Surface Preparation

  • Clean the bonding surface to remove dust, oil, grease, and contaminants.
  • Ensure the surface is dry and ready for treatment.

Step 2: Apply 3M K500NT

  • Apply a thin and uniform layer of adhesion promoter to the bonding area.
  • Avoid excessive application, which may reduce adhesive effectiveness.

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 substrate.

Step 5: Allow Bond Development

  • Allow sufficient time for the adhesive bond to develop before applying mechanical stress.

Storage

  • Store in the original sealed container.
  • Keep in a cool, dry, and ventilated area.
  • Protect from direct sunlight and excessive heat.
  • Keep container tightly closed when not in use.
  • Follow recommended storage conditions and shelf-life guidelines.

FAQ

Q1: What is 3M Adhesion Promoter K500NT used for?
