Installation Guide
Step 1: Surface Preparation
- Clean the bonding surface to remove dust, oil, grease, and contaminants.
- Ensure the surface is clean and completely dry before treatment.
Step 2: Apply 3M K520UV
- Apply a thin, uniform layer of adhesion promoter to the bonding area.
- Avoid excessive coating thickness.
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 the adhesive tape with firm and consistent pressure.
- Ensure full contact between adhesive and treated substrate.
Step 5: Allow Bond Development
- Allow sufficient time for the adhesive bond to develop before exposing the assembly to heavy stress.
Storage
- Store in the original sealed container.
- Keep in a cool, dry, and well-ventilated area.
- Avoid direct sunlight and excessive heat.
- Keep container tightly closed when not in use.
- Follow recommended storage conditions and shelf-life guidelines.
