Notes On Adhesive K1 (Cooper, Cooper S, John Cooper Works)
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°- 25°C.
Shelf life:
The glue cartridge is marked with a date.
Do not use the adhesive after this date.
Surface pre-treatment:
The Pre-Treatment depends on the material to be bonded and its coating (See BONDING STEEL ON STEEL (COOPER, COOPER S, JOHN COOPER WORKS) ).
Required cartridge gun:
OVERVIEW OF GLUE CARTRIDGE GUNS .
Do not use compressed-air-operated cartridge guns!
Preparing the glue cartridge:
Opened glue cartridges may be used again before the expiry date as long as a new mixing tube is used. The working temperature of glue cartridge must be at least 20°C.
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. Allow approx. 10 cm of mixed adhesive to emerge.
Only then apply the mixed adhesive to one side of the bonding surface.
Processing time of mixed adhesive approx. 2 hours. A change of mixer is only necessary if over a period of 1 hour no material has flowed through the mixer.
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.
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 a mixture of adhesive and solvent and the like must be disposed of as hazardous waste.
This information applies to the Federal Republic of Germany.
In other countries, the locally applicable regulations must be applied. These may deviate from those applicable in the Federal Republic of Germany.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
