Application methods
2K-Derocryl Hydro PD796
Mixing ratio
- Stirr intensively with mechanical stirrer
- Mix base paint and hardener according to the mixing ratio as specified
- Afterwards add 4 % water.
Airless spraying
- 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 inch (0,28 mm)
- Spraying angle according to the geometry and size of the object to be laquered
Compressed air spraying
- Spraying pressure 2 - 4 bar
- Nozzle size 1,5 - 1,6 mm
- Adjust to spraying viscosity (appr. 40 s DIN 4 mm) adding appr. 4 % 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
Thinner
- Max. 4% 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, soluble residues from chemical pretreatments and zinc reaction products 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: 2K-Hydropox Protec ZP*
