Application methods
2K-Derocryl Lack 80 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 0,011 - 0,015 inch (0,28 - 0,38 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 1,3 - 1,6 mm
• Adjust to spraying viscosity (appr. 40 s DIN 4 mm) adding appr. 10 % Derocryl-Verdünnung (two component products: after mixing)

Electrostatic application

• Can be applied as delivered
• Conductance of the material: 700 kΩ

Dipping

• Can not be applied as delivered

Other methods

• Roller and brush application for repair work is possible

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
• 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 and drying the environmental temperature should be min. 5°C / max. 30°C
• Object temperature at least 3° C above dew point.
