Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Body Structural Adhesive D 180 004 M2, Application: Notes
Bonded Joints, Detaching
Body bonded joints can be detached by applying heat. The adhesives used in the vehicle construction and the repair are destroyed at temperatures 180 - 200°C (356 to 392 °F).
Wear protective gloves and eyewear.
Avoid direct contact of the adhesives with the skin.
Avoid inhaling solvent vapors.
Only process adhesives in well-ventilated areas.
Always note the hazard information from the manufacturer.
Also note the accident prevention regulations applicable in the respective country.
Note the corresponding safety data sheets for the adhesive.
Do not smoke, eat or drink at the work station.
Use suitable extraction.
- The vehicle, parts and adhesive materials must be at processing temperature (acclimated). The processing temperature must be kept for 30 min before work on the adhesive surfaces starts.
- The adhesive surfaces must be free of oils, adhesive residue, humidity, paint and oxide coatings.
- Body structural adhesive must only be used on bare metal components.
- Only use sanding material based on silicon carbide (SIC) for grinding down the adhesive surface.
- Pay attention that the cleaned surfaces are only touched with clean gloves in order to avoid transferring hand sweat or contamination to the adhesive surface.
- Merging must happen immediately after applying the adhesive, in order to ensure a high-quality and secure bonding. Otherwise the adhesive bead must be removed and the surface treatment and application of the adhesive must be repeated.
- Carefully prime the accessible adhesion areas after hardening and seal them with body sealant. Protect adhesion areas in cavities against corrosion using cavity sealant.
Use the adhesive material within the processing time. Within this timeframe the adhesive material must be applied and connected to the body component. Any resistance weld spots or mechanical joining processes (for example rivets and bolts) in the area of the adhesive must be performed within this timeframe.
Do not stress bonded parts until hardened.

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.
