Installation Guide
Step 1: Clean the Surface
- Ensure the bonding area is clean, dry, and free from dust, oil, grease, and contaminants.
- Use a suitable cleaning method before applying the promoter.
Step 2: Apply 3M AC-137
- Apply a thin and even layer of adhesion promoter to the bonding area.
- Avoid excessive coating, which may affect adhesive performance.
Step 3: Allow Drying
- Allow the surface treatment to dry completely before applying the adhesive tape.
- Drying time depends on temperature, humidity, and application environment.
Step 4: Apply Adhesive Tape
- Apply the tape with firm, uniform pressure.
- Ensure complete contact between adhesive and treated surface.
Step 5: Allow Bond Strength Development
- Allow sufficient bonding time before exposing the assembly to heavy loads or stress.
Storage
- Store in the original sealed container.
- Keep in a cool and dry location.
- Avoid direct sunlight and high temperatures.
- Keep container closed when not in use.
- Follow recommended storage conditions and shelf-life guidelines.
