General:
Sound insulation is bonded to the inner door panel.
Bonded sound insulation must not be subjected to load (e.g. leak test) before 5 hours have elapsed.

On-the-job safety:
When working with bonding products (adhesive, cleaning agent, etc.):
- Wear safety goggles, protective gloves and if necessary an apron.
- Ensure rooms are well ventilated.
- Change work clothing contaminated with adhesive immediately.
- Change work clothing contaminated with solvents and swelling agents immediately (keep spare work clothing on hand).
- Take skin protection measures, provide washing facilities including hot water, use silicone-free skin creams
- Provide eye douche facilities, change water regularly (once a month).
- Comply with the relevant safety regulations










The sound insulation must be bonded watertight below the door lock:
- Flat bonding surface required all round
- No bonding in event of moisture (e.g. condensation, etc.)
- Bonding area must not show any traces of adhesion-reducing residues (e.g. separating agents, greases, oils, paraffins, plastisols, cavity wax, polishing dust residues, etc.)
- Remove the protective film directly before joining (under no circumstances remove earlier, since the butyl, because of its stickiness, will very quickly pick up adhesion-reducing dirt contaminants)
- The sound insulation must be attached with positional accuracy to the inner door panel, because it is no longer possible to change the position without damaging the butyl bead
- With repainted areas, the maximum permitted temperature of 90V may not be exceeded in the area of the sound insulation. Otherwise, the sound insulation must be removed (and replaced, if necessary).

Expiry date of adhesive:
24 months, see label on packaging

Disposal of the cleaning cloth:

Disposal of adhesive:
