- Suitable for the application on automatical equipments
Compressed air spraying
- Can be applied as delivered
- Spraying pressure 4 bar
- Nozzle size 1,3 - 1,5 mm
Electrostatic application
- Application is possible, provided the equipment is suitable for water based materials
Dipping
- Can be applied as delivered
Other methods
- Roller and brush application for repair work is possible
Thinner
- Max. 3% Water
Cleaning
- Rinse immediately with Water
- Residues are dissolvable with Deripox-Verdünnung
Preparation of support
- Shot blasting to a purity according to SA 2½
- Mill scale, welding residues, dust and dirt on the surface which might reduce adhesion have to be carefully and thoroughly removed
General remarks
- During coating and drying the humidity should be min. 30 % / max. 85 %
- Object temperature at least 3° C above dew point.
