Application methods
Derozink Silikon Alu

Airless spraying

  • Flow pressure 160 - 180 bar
  • Nozzle size 0,009 - 0,011 inch (0,23 - 0,28 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 - 1,8 mm
  • Adjust to spraying viscosity (appr. 30 s DIN 4 mm) adding appr. 8 % Deripox-Verdünnung (two component products: after mixing)

Electrostatic application

  • Application is not possible


  • Can not be applied as delivered

Other methods

  • Roller and brush application for repair work is possible


  • Max. 10% Deripox-Verdünnung


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

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.
