WARNING:
Toxic substances
- Danger of poisoning or suffocation

→ Never ingest or inhale.
→ Read specific information on the Hazard Sheet.
→ Wear personal protective gear.
Information
- In addition to this manual, observe the relevant job descriptions for body repairs!
Information
- Bonding surfaces must be free from oil, old adhesive, dirt, moisture, and layers of paint and oxide.
- Body structural adhesive must only be used on bare metal components.
- To improve adhesion, the bonding surface must be roughened with sandpaper. Remove paint layers (cathodic immersion painting) using dry sandpaper or fibre discs with a grain of 100 to 150.
- The bare bonding surface must then be cleaned with a lint-free cloth soaked in acetone.
- Leave cleaned areas to dry for approx. 1-2 minutes. Bonding areas must be completely dry. Dispose of the used, acetone-soaked cleaning cloth as special-category waste.
- Ensure that clean gloves are worn when touching cleaned surfaces to avoid transferring sweat from the hands and dirt onto the bonding area.
- The jointing operation must take place directly after application of the adhesive in order to guarantee a high quality and reliable bond. Otherwise the adhesive bead must be removed, with pre-treatment of the surface and application of the adhesive being repeated.
