Instructions for applying Rokopur Struktopur RK 403 paint

 

  • First, the first spray is made with Rokopur Struktopur RK 403, which is diluted a lot for this purpose, viscosity approx. 35 s. A thickness of 30-50 μm is applied. Airless high-pressure equipment (pressure 150 atm.) Or a low-pressure air gun (pressure 4-5 atm.) Can be used for the application.
  • After drying - about 30 minutes, a second spray of Struktopur paint is performed. The paint is no longer diluted - it is sprayed in the supply viscosity, the pressure during spraying is low - approx. 1.5 atm. During spraying, a specific structure is created. Thickness is no longer important here. By adjusting the viscosity and pressure, the desired fineness of the structure is selected. It is advisable to consult the recommended type of spray gun used with the upper container, with the addition of air to the container with the paint manufacturer.
  • Initial pre-reaction of the hardened mixture of structural color for 15 min. before spraying - the interval from hardening to spraying - must be strictly observed.

Previous Edit


The substrate must be free of dust, rust, scale, oil, grease and old paint residues. Degreasing and mechanical cleaning for min. St 2 or or blasting to a surface cleanliness of Sa 2.5 (ISO 8501-1) is more suitable
Furthermore, the substrate is provided with a primer - eg anti-corrosion coating Rokoprim acrylic RK 102 or Rokopur primer RK 105 or Rokoprim EP S 2300. The recommended thickness of the primer is, depending on the corrosion load of the product - most often from 40-80 μm.
