Surface Preparation


Immersion Exposure

  • Steel or steel with not appoved zinc silicate shop primer: blast cleaned to ISO-Sa2½, blasting profile 30 - 75 μm (1.2 – 3.0 mils).
  • Steel with approved zinc silicate shop primer; weld seams and areas of damaged shop primer or breakdown should be blast cleaned to ISO-Sa2½, blasting profile 30 - 75 μm (1.2 – 3.0 mils) or power tool cleaned to SPSS-Pt3.
  • Coated steel; hydrojetted to VIS WJ2L (blasting profile 30 – 75 μm (1.2 – 3.0 mils).
  • Previous coat must be dry and free from any contamination.

IMO-MSC.215(82) Requirements For Water Ballast Tanks

  • Steel; ISO 8501-3: 2006 grade P2, with all edges treated to a rounded radius of minimum 2 mm (0.0789 in) or subject to three pass grinding.
  • Steel or steel with not appoved zinc silicate shop primer: blast cleaned to ISO-Sa2½, blasting profile 30 - 75 μm (1.2 – 3.0 mils).
  • Steel with approved zinc silicate shop primer; weld seams and areas of shop primer damage or break down should be blast cleaned to Iso-Sa 2½ blasting profile 30 – 75 μm (1.2 – 3.0 mils): [1] For shop primer with IMO type approval; no additional requirements; [2] For shop primer without IMO type approval; blast cleaned to ISO-Sa2 removing at least 70% of intact shop primer, blasting profile 30 – 75 μm (1.2 – 3.0 mils).
  • Damages up to 2% of the total area of the tank may be treated to ISO-St3. Damages over 2% of the total area of the tank or contiguous damages over 25 m² (269 ft²) have to be blast cleaned to ISO-Sa2½.
  • Dust quantity rating "1 for dust size class "3", "4" or "5", lower dust size classes to be removed if visible on the surface to be coated without magnification (ISO 8502-3:1992).
  • Previous coat must be dry and free from any contamination.

Atmospheric Exposure Conditions

  • Steel; pretreated preferably to ISO-Sa2½, , blasting profile 30 – 75 μm (1.2 – 3.0 mils) or according to ISO-St3.
  • Shop primed steel; pretreated to SPSS-Pt3.
  • Galvanized steel must be free from grease, salts and any contamination.
  • Galvanized steel must be sweep blasted or otherwise roughened.
  • Coated steel; hydrojetted to VIS WJ2L (blasting profile 30 – 75 μm (1.2 – 3.0 mils).
  • Previous coat must be dry and free from any contamination.

Substrate Temperature & Application Conditions

  • Substrate temperature during application and curing should be above 5°C (41°F).
  • Substrate temperature during application and curing should be at least 3°C (5°F) above dew point.
  • Relative humidity during application and curing should not exceed 85%.



Application Methods


Mixing Ratio By Volume: Base To Hardener 80:20 (4:1)

  • The temperature of the mixed base and hardener should preferably be above 15°C (59°F), otherwise extra thinner may be required to obtain application viscosity.
  • Adding too much thinner results in reduced sag resistance and slower cure.
  • Thinner should be added after mixing the components.

Induction Time:

  • None

Pot Life:

  • 4 hours at 20°C (68°F)

Airless Spray:

  • Recommended Thinner: THINNER 91-92
  • Volume Of Thinner: 0 - 10%, depending on required thickness and application conditions
  • Nozzle Orifice: Approx. 0.46 – 0.53 mm (0.018 – 0.021 in)
  • Nozzle Pressure: 20.0 - 25.0 MPa (approx. 200 - 250 bar; 2901 - 3626 p.s.i.)

Brush/Roller:

  • Brush: for stripe coating and spot repair only
