Technical Information Bitumen Based Undercoating
MoTip Underbody Protection (Bitumen) forms a delicate elastic, durable seal on the underside of machines, vehicles and wheel cases for all types of vehicles. It protects the undersides from the mechanical and chemical stress of stone chipping, grit, water, rust and the effects of weather.
Thixotropic properties mean the spray can be applied in thick layers without running.
For use:
on bodywork, in workshops, bus construction, at home
Available in 500ml spray cans and also in 1 litre spray gun cans as well as in 1.3 kg and 2.5 kg paint cans.

Environment and labelling
Environmentally sound: European Aerosols is committed to apply formulations without restricted or critical ingredients and to achieve best possible performance. The caps and packagings are made of recyclable material.
Disposal: Only the completely emptied cans should be put into the recycling skip or appropriate container for reclaimable refuse. Cans which are not empty should be disposed off as "special refuse".
Marking/Labelling: All products made by European Aerosols comply with the actual labelling regulations according to Preparation Guideline 1999/45/EG. All aerosols correspond to TRGS 200 and TRG 300 as well as to aerosol guideline 75/324/EWG in the actually valid version.
The water-based underbody protection cannot be painted over. For visible bodywork, we recommend applying a topcoat of MoTip stone chipping protection.
Application spray can:
- Remove old paintwork and rust, then sand.
- Surface should be clean, dry and free of grease.
- Bring the can to room temperature.
- Processing temperature15 to 25°C.
- Shake can before use and test spray.
- Apply several thin coats from a distance of ca. 25 to 30 cm.
- After use, turn can and spray empty to clean the valve.
Application spray gun can:
- The surface should be clean, dry and free of grease.
- Shake before use.
- Screw 1000ml bottle in special compressed-air spray gun.
- Operational pressure 3 to 6 bars.
- Apply underside protection in the desired thickness.
- With thick layers, leave individual layers to dry.
- Sprays without forming mist, and does not leave dangling threads or drips..
- Fresh dirt on equipment can be cleaned with solvents if necessary.
Application paint can:
- The surface should be clean, dry and free of grease.
- MoTip underside (bitumen) can be applied in thick coats without dripping with a paintbrush or spatula.
- With thick layers, leave individual layers to dry.
- Thin with solvent according to use.
Tips for spray painting
Protect the object and the surrounding area from spray mist.
Temperature should range between +10°C and +25°C, max. air humidity 60 %.
Store in a dry place. Protect from direct sunlight and other sources of heat. Use only during dry weather, in places protected from the wind, and in well-ventilated rooms. Follow the warning texts on the labels!
