51 00... Notes on film bonding
- General notes:
- Bonding at room and object temperature of 18 to 25°C.
- Newly painted parts may only be bonded after a drying time of at least 24 hours.
- Optimal bonding with the background surface is achieved after approx. 48 hours. Components must not be exposed to mechanical strain beforehand (car wash, strength test, etc.).
- Auxiliary materials and tools:
- Spirit, plastic squeegee, needle, cleaning cloth
- Low-surface-tension water
NOTE: Mixture ratio: 3 drops of agent that reduces water surface tension (washing-up liquid) for 1 L tap water. - Preparations:
- If necessary, warm up faulty/existing foil with hot air blower and pull off
- Remove all adhesive residue or clean new part thoroughly
- Immediately before bonding, use spirit to clean the areas to be bonded to remove silicone and grease residues.
NOTE: Observe ventilation time ≥1 minute. - Bonding:
- 4.1 Wet bonding
- Wet the adhesive surface thoroughly with low-surface-tension water.
- Place the foil on the surface by pulling off backing film and adjust the position.NOTE: For small foils, the backing film can be completely pulled off and the foil can be additionally wetted on the adhesive side with low-surface-tension water.
- Using a plastic squeegee, press down the foil from the inside to the outside with overlapping strokes.
- Remove the remaining water with a clean cloth.
- If necessary, carefully and slowly pull off protective film in a flat direction.
- Check the foil for bubbles and creases. If necessary, remove bubbles or creases with plastic squeegee or puncture with needle and squeeze out air or water.
- 4.2 Dry bonding
- Pull off backing film on adhesive side.
- Position foil in the correct position on the motor vehicle.
- Using a plastic squeegee, press down foil with overlapping strokes (watching for bubbles and creasing).
- If necessary, carefully and slowly pull off protective film in a flat direction.
- If necessary, puncture bubbles with needle and squeeze out air with plastic squeegee.
