Suitable Substrates

  • steel
  • galvanized steel
  • suitable coatings with adequate adhesion

Substrate Preparation

The surface has to be dry and free of fat, oil, dirt and dust.

  • Steel: For high corrosive environment  grid blasting Sa 2½ (DIN EN ISO 8501-1), surface profile medium (G) (ISO 8501-1). For lower corrosivity (i. g. indoor without condensing water and low corrosive impact) surface must at least be very thoroughly hand and powertool cleaned St3 (DIN EN ISO 8501-1).
  • Galvanized steel: Remove white rust and other contamination via grinding (abrasive paper or pad), ammonia-water solution containing wetting agent or sweep blasting (DIN EN ISO 12944-4). Corroded spots must be very thoroughly hand and powertool cleaned PSt3 (DIN EN ISO 8501-1).
  • Old coatings: Compatible old coatings can be overcoated after suitable surface preparation and adequate adhesion. When in doubt, a coating test area is recommended. Good adhering coatings must be cleaned and roughened. Corroded spots must be very thoroughly hand and powertool cleaned PSt3 (DIN EN ISO 8501-1).

    Alternatively old coatings can be prepared by water jetting down to a compatibel, well adhearing coat or rough steel surface to Wa 2½ (ISO 8501-4), flash rust grade M.

    Badly adhearing coatings must be removed completely by grid blasting Sa 2½, hand and powertool cleaning St3 (both DIN EN ISO 8501-1) or water jetting Wa 2½ (ISO 8501-4), flash rust grade M.

Preparation of Material

Stir component A until homogeneous. Then mix component A and B at specified mixing ratio, stir thoroughly (aprox. 3 min.) with a slow rotating stirrer (max. 400 r/min). Repot the mixture in a clean pot and stir again thoroughly.

Mix only the quantity, which can be applicated within the pot life.

Mixing Ratio

90 parts by weight comp. A
10 parts by weight comp. B

Method of Application

  • Brush
  • Roller

  • Airless spray application (spray nozzle pressure 160 - 200 bar, nozzle size 0,38 - 0,48 mm respectively 0,015 - 0,019 inch)
    For airless spray application it is allowed to add up to 5 % DisboADD 419, depending on the dry film thickness and application conditions.

Layer Thickness

Dry film thickness 80 µm, equal to 135 µm wet film thickness

Surface Coating System

  • Steel:
    Prime coat: 1 - 2 x DisboCOR 871 2K-EP Phosphate
    Intermadiate coat: 1 - 2 x DisboCOR 873 2K-EP Zwischenschicht EG
