Application methods
2K-Derocryl Haftgrund EG HS

Mixing ratio

• Stirr homogeneous, preferably with mechanical stirrer
• Mix base paint and hardener according to the mixing ratio as specified

Airless spraying

• Flow pressure 180 bar
• Nozzle size 0,013 - 0,017 inch (0,33 - 0,43 mm)
• Spraying angle according to the geometry and size of the object to be laquered

Compressed air spraying

• Spraying pressure 5 - 6 bar
• Nozzle size 1,8 - 2,3 mm
• Adjust to spraying viscosity (appr. 60 s DIN 4 mm) adding appr. 8 % Derocryl-Verdünnung (two component products: after mixing)

Electrostatic application

• Application is not possible

Dipping

• Can not be applied as delivered

Other methods

• Roller and brush application is possible in the quality as delivered
• Double application is possible in viscosity as delivered

Thinner

• Max. 10% Derocryl-Verdünnung

Cleaning

• Rinse immediately 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
• 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
• Cleaning with alkaline wetting agent

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.
