Application methods
2K-Derocryl finish GL

Mixing ratio

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

Airless spraying

• Firstly apply a mist layer with diluted material
• Flow pressure 150 - 210 bar
• Nozzle size 0,009 - 0,013 inch (0,23 - 0,33 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
• Do not exceed wetfilm thickness of 100 µm (blistering)

Compressed air spraying

• Can be applied as delivered
• Spraying pressure 2 bar
• Nozzle size 1,3 - 1,6 mm
• Adjust to spraying viscosity (appr. 20 s DIN 4 mm) adding appr. 5 % Derocryl-Verdünnung (two component products: after mixing)

Electrostatic application

• Can be applied as delivered
• Conductance of the material: 800 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

• 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
• Clean primer of the coating system

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-Derocryl Haftgrund HS
• Finish coat: 2K-Derocryl finish GL
