Application methods
2K-Derocryl Hammerschlag Lack

Mixing ratio

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

Airless spraying

• Too high pressure and/or too high working viscosity can cause blister which may impair the effect
• Flow pressure 130 - 160 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
• If required (two component: after mixing) using 5% Derocryl-Verdünnung is possible

Compressed air spraying

• Can be applied as delivered
• Spraying pressure 2 bar
• Nozzle size 1,6 - 2 mm

Electrostatic application

• Application is not possible

Dipping

• Can not be applied as delivered

Other methods

• Roller and brush application is inadvisable

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 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. 10 % / 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.
