1K-Derocryl Haftgrund EE


  • In dry, cool rooms, if possible frost-proof
  • Ensure good ventilation

Shelf life

  • 6 month from date of delivery when in unopened original containers in cool and dry conditions

Application methods
1K-Derocryl Haftgrund EE

Airless spraying

  • Risk of spray dust due to very fast drying
  • Flow pressure 120 - 150 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 - 2 mm
  • Adjust to spraying viscosity (appr. 30 s DIN 4 mm) adding appr. 5 % Derocryl-Verdünnung (two component products: after mixing)

Electrostatic application

  • Application is possible, provided that the material is set to the appropriate conductance for the system concerned
  • It should be noted that,adapting the material to the appropriate conductance for the system concerned,may prolong drying and impair the resistance to corrosion and weathering


  • Can not be applied as delivered

Other methods

  • Roller and brush application is inadvisable


  • Max. 5% 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 the environmental temperature should be min. 5°C / max. 30°C
  • Object temperature at least 3° C above dew point.
