Application methods
1K-Derocryl Haftgrund EE
Airless spraying
- Risk of spray dust due to very fast drying
- Flow pressure 120 - 150 bar
- Nozzle size 0,009 - 0,011 inch (0,23 - 0,28 mm)
- Spraying angle according to the geometry and size of the object to be laquered
Compressed air spraying
- Spraying pressure 3 - 5 bar
- Nozzle size 1,5 - 2 mm
- Adjust to spraying viscosity (appr. 30 s DIN 4 mm) adding appr. 5 % Derocryl-Verdünnung (two component products: after mixing)
Electrostatic application
- Application is possible, provided that the material is set to the appropriate conductance for the system concerned
- It should be noted that,adapting the material to the appropriate conductance for the system concerned,may prolong drying and impair the resistance to corrosion and weathering
Dipping
- Can not be applied as delivered
Other methods
- Roller and brush application is inadvisable
Thinner
- Max. 5% Derocryl-Verdünnung
Cleaning
- Rinse immediately with Derocryl-Verdünnung
- Residues are dissolvable with Derocryl-Verdünnung
Preparation of support
- Shot blasting to a purity according to SA 2½
- If necessary clean with high pressure-cleaner and turbo-cleaner-solution
- Sweeping for zinced supports
- 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 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: 1K-Derocryl Haftgrund EE
