Application methods
Deritex 40 HS

Airless spraying

  • Risk of spray dust due to very fast drying
  • 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

  • Nozzle size 1,3 - 2 mm
  • Adjust to spraying viscosity (appr. 45 s DIN 4 mm) adding appr. 10 % Derozink-Verdünnung (two component products: after mixing)

Electrostatic application

  • Application is possible provided that the material is diluted

Dipping

  • Can not be applied as delivered

Other methods

  • Roller and brush application for repair work is possible

Thinner

  • Max. 10% 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

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.
