41 00... Installing A Cavity Acoustic Baffle With 2-Component PU Cavity Foam: Notes
WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2014 BMW X6, 2013 BMW X6, 2012 BMW X6, 2011 BMW X6, and 2010 BMW X6. However, it is still accessible from the selected car via links, so may be relevant.
IMPORTANT:
The cavity foam may only be use for cavity sealing at the points at which cavity sealing is present as standard!
The following repair represents the replacement of a shaped part for the cavity seal by the use of cavity foam.
This type of cavity sealing is used at points at which shaped parts cannot be used for repairs.
This is the case when large amounts of heat occur (e.g. due to welding, soldering or tin-plating) in the direct vicinity or at the point of the standard cavity sealing.
It is not possible here to install shaped parts for the cavity seal because of the fire risk!
To replace shaped parts with cavity foam at further locations, adopt the procedure shown here and adapt it to the relevant conditions.
It must be ensured that the cavity is completely sealed off.
NOTE:
Check the accessibility for the spraying pipe of the cavity foam to the affected cavity after removing the damaged part.
Properties of cavity foam:
- 2-component PU foam, solvent-free.
- Excellent flow capacity, enabling complete sealing of cavities.
- Good strength, preventing slipping in cavities.
- Low water absorption, preventing corrosion.
- Ideal for use as insulating and sealing compound.
