Application methods
1K Derocryl DTM Hydro
Airless spraying
- Risk of spray dust due to very fast drying
- After using the material close the packings immediately
- Dip the pistol and the nozzle into water during the breaks
- It is tending to fast skinning. Do not stir the skin in any case!
- Flow pressure 120 - 160 bar
- Nozzle size 0,011 - 0,013 inch (0,28 - 0,33 mm)
Compressed air spraying
- Spraying pressure 2 - 4 bar
- Nozzle size 1,3 - 1,5 mm
- Adjust to spraying viscosity (appr. 40 s DIN 4 mm) adding appr. 5 % Water (two component products: after mixing)
Electrostatic application
- Application is possible, provided the equipment is suitable for water based materials
Dipping
- Can not be applied as delivered
Other methods
- Roller and brush application for repair work is possible
Thinner
- Max. 8% Water
Cleaning
- Rinse immediately with Water
- Residues are dissolvable with Deripox-Verdünnung
Preparation of support
- Shot blasting to a purity according to SA 2½
- If necessary clean with high pressure-cleaner and turbo-cleaner-solution
- 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 %
- During coating and drying the environmental temperature should be min. 5°C / max. 30°C
- Object temperature at least 3° C above dew point.
Example for a system
- Primer coat: Derocryl Grund Hydro GT
- Finish coat: 1K Derocryl DTM Hydro
