Application methods
2K-Derocryl Haftgrund HS

Mixing ratio

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

Airless spraying

  • Flow pressure 210 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

  • Spraying pressure 2 bar
  • Nozzle size 1,3 - 1,6 mm
  • Adjust to spraying viscosity (appr. 40 s DIN 4 mm) adding appr. 10 % Derocryl-Verdünnung (two component products: after mixing)

Electrostatic application

  • Application is possible provided that the material is diluted
  • Conductance of the material: 800 kΩ


  • Can not be applied as delivered

Other methods

  • Roller and brush application for repair work is possible


  • Max. 15% Derocryl-Verdünnung


  • Rinse immediately with Derocryl-Verdünnung
  • Residues are dissolvable 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
  • Sweeping for zinced supports
  • 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. 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.
