Application methods
Derozink Alu

Mixing ratio

• Stirr intensively with mechanical stirrer

Airless spraying

• Flow pressure 180 bar
• Nozzle size 0,011 - 0,014 inch (0,28 - 0,36 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 mm
• Adjust to spraying viscosity (appr. 30 s DIN 4 mm) adding appr. 5 % Derozink-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

Thinner

• Max. 5% Derozink-Verdünnung

Cleaning

• Rinse immediately with Derozink-Verdünnung
• Residues are dissolvable with Derozink-Verdünnung

Preparation of support

• Shot blasting to a purity according to SA 2½
• Mill scale, welding residues, dust and dirt on the surface which might reduce adhesion have to be carefully and thoroughly removed
• 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. 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.

Example for a system

• Finish coat: EPE Einschichtlack
