Notes On Adhesive K5 (M3 Base, M3 Competition, M3 Competition M xDrive, M3 CS)
Attention!
Note the following information before starting to apply adhesive!
- Country-specific safety and industrial safety regulations
- Material safety data sheet of manufacturer
- Processing instructions on glue cartridge
Storage:
Dry at 15°- 32°C
Shelf life:
The glue cartridge is marked with a date
Do not use the adhesive after this date
Surface pre-treatment:
See vehicle-specific repair instructions
Required cartridge gun:
OVERVIEW OF GLUE CARTRIDGE GUNS .
Check cartridge gun:
The piston crown of the cartridge gun must have an even contact surface. Parts must not stand out from the contact surface, since this can lead to damage to the floor of the glue cartridge
During the initial use of a new cartridge gun, begin with the slowest feed rate
Afterwards, increase the feed speed only so much that the glue cartridge is not damaged
Preparing the glue cartridge:
The working temperature of glue cartridge must be at least 20°C
Opened glue cartridges may be used again before the expiry date as long as a new mixing tube is used
Insert the glue cartridge into the cartridge gun
Manually press the piston rod against the bottom of the glue cartridge
Remove the cap and allow both adhesive components to escape. Strip adhesive components uniformly and attach mixing tube. Use only the mixing tubes supplied with the glue cartridge
Before starting to apply adhesive, allow approx. 1 mixing tube length of mixed adhesive to emerge. Only then apply the mixed adhesive on one side of the bonding surface
Pot life of adhesive is approx. 60 minutes at 23°C
2-component adhesive application:
Refer to the vehicle-specific REP for the position and thickness 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 BMW hotline
Remove contamination caused by adhesive residue immediately
Hardened adhesive can only be removed mechanically
Hardening time:
Do not shift the vehicle before the adhesive has hardened
Check the degree of hardness of the adhesive with a fingernail
If the adhesive can no longer be pressed in with the fingernail, the vehicle can be moved for further processing steps (for example, paintwork) (without engine power)
The strength for driving of the vehicle is reached after:
48 hours at an object temperature of 15°C
10 hours at an object temperature of 23°C
1 hour at an object temperature of 60°C
0.5 hours at an object temperature of 85°C
Attention!
When using radiant heaters, the object temperature must not exceed 85°C. Excessively high temperatures will destroy the adhesive
Disposal of adhesive:
Hardened adhesive is disposed of as normal waste
Empty glue cartridges are disposed of as normal waste
Non-hardened adhesives and mixtures of adhesive and solvent and the like must be disposed of as hazardous waste
