Application methods
1K Derocryl DTM Hydro ZN

Airless spraying

  • Risk of spray dust due to very fast drying
  • After using the material close the packings immediately
  • Dip the pistol and the nozzle into water during the breaks
  • It is tending to fast skinning. Do not stir the skin in any case!
  • Flow pressure 120 - 160 bar
  • Nozzle size 0,011 - 0,013 inch (0,28 - 0,33 mm)

Compressed air spraying

  • Spraying pressure 2 - 4 bar
  • Nozzle size 1,3 - 1,5 mm
  • Adjust to spraying viscosity (appr. 40 s DIN 4 mm) adding appr. 5 % Water (two component products: after mixing)

Electrostatic application

  • Application is possible, provided the equipment is suitable for water based materials


  • Can not be applied as delivered

Other methods

  • Roller and brush application for repair work is possible


  • Max. 8% Water


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

Preparation of support

  • 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
  • Cleaning with alkaline wetting agent

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.
