Application methods
2K-Deripox Zinkstaub 687.03

Mixing ratio

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

Airless spraying

  • Risk of spray dust due to very fast drying
  • Flow pressure 180 bar
  • Nozzle size 0,019 - 0,021 inch (0,48 - 0,53 mm)
  • Spraying angle according to the geometry and size of the object to be laquered
  • If required (two component: after mixing) using 5% Deripox-Verdünnung (687.150) is possible

Compressed air spraying

  • Spraying pressure 5 - 6 bar
  • Nozzle size 1,5 - 2 mm
  • Adjust to spraying viscosity (appr. 30 s DIN 4 mm) adding appr. 10 % Deripox-Verdünnung (687.150) (two component products: after mixing)

Electrostatic application

  • Application is not possible

Dipping

  • Can not be applied as delivered

Other methods

  • Roller and brush application for repair work is possible

Thinner

  • Max. 10% Deripox-Verdünnung (687.150)

Cleaning

  • Rinse immediately with Deripox-Verdünnung (687.150)

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. 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.
