2.0 Preparation of surface
2.1 Steel surface
2.2 Aluminium surface
2.2.1 Procedure for new aluminium component
2.2.2 Procedure for previously bonded aluminium component
3.0 Adhesive application
- Processing temperature of glue cartridge 18ºC - 30ºC.
- Object temperature, vehicle and new parts, min. 15ºC.
- Read the vehicle-specific repair instructions to determine the thickness
and positioning of the adhesive
bead.
- After applying the adhesive, check whether an adhesive component has
emerged at the back of the glue
cartridge. If yes, break off the bonding procedure. Clean new part. Use new
glue cartridge. Contact
national hotline.
- Join components and secure in position.
- Remove excess adhesive. Do not use solvent cleaning agents.
3.1 Bonding in conjunction with repair elements (expanding elements)
- Repair elements are special shaped parts to connect new parts with the
body. e.g. Partial replacement of
engine support.
- The repair elements will spread when a special bolt is screwed in. The
repair elements will thereby
connect flush to the corresponding profile shape.
- Ensure there is a sufficient gap between the adhesive and the threads
for the expander screws (approx. 10-
15 mm).
- Spread adhesive over the repair element with a spatula up to the height
of the ridges.
3.2 Bonding in conjunction with rivets
4.0 Hardening times
- Refer to NOTES REGARDING ADHESIVE K1
5.0 Subsequent treatment
- Protect the repair area with cavity sealant.
