Surface Preparation


Recommended Substrate Conditions and Temperatures

Immersion exposure

  • Steel or steel with not approved zinc silicate shop primer; blast cleaned (dry or wet) 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))
  • Primed steel or previous coat must be dry and free from any contamination

 

IMO-MSC.215(82) Requirements for Water Ballast Tanks and IMO-MSC.288(87) for Cargo tanks of Crude Oil Tankers (specified areas only)

  • Steel; ISO 8501-3:2006 grade P2, with all edges treated to a rounded radius of minimum 2 mm (0.079 in) or subject to three pass grinding or at least equivalent process before painting
  • Steel or steel with not approved 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)
  • Dust quantity on the surface to be coated must not exceed rating "1" for dust size class "3", "4" or "5" (ISO 8502-3-2017). Lower dust size classes (“1” and/or “2”) to be removed if visible without magnification.
  • Primed steel or previous coat must be dry and free from any contamination

 

Atmospheric exposure conditions

  • Steel; blast cleaned 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 cleaned by solvent or roughened by sandpaper
  • Coated steel; hydrojetted to VIS WJ2L (blasting profile 30 – 75 µm (1.2 – 3.0 mils))
  • Primed steel or 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


Instructions for Use

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.

 

Air spray


Recommended thinner

Volume of thinner

  • 0 - 15%, depending on required thickness and application conditions

Nozzle orifice

  • 1.5 – 2.0 mm (approx. 0.060 – 0.079 in)

Nozzle pressure

  • 0.3 - 0.4 MPa (approx. 3 - 4 bar; 44 - 58 p.s.i.)

 

Airless spray


Recommended thinner

  • THINNER 91-92

Volume of thinner

  • 0 - 15%, depending on required thickness and application conditions

Nozzle orifice

  • Approx. 0.53 – 0.74 mm (0.021 – 0.029 in)

Nozzle pressure

  • 15.0 MPa (approx. 150 bar; 2176 p.s.i.)

 

Brush/roller


Recommended thinner

  • No extra thinner is necessary

Volume of thinner

  • Up to 5% THINNER 91-92 can be added if desired

Note:

  • Note: Max. dft: Dry Film Thickness of 2000 µm (80.0 mils) may occur occasionally (minor areas) where multiple overlapping is unavoidable (i.e. around scallops, corners, erection joint lines etc.). PPG/Rawlins Paints must be consulted (0113 2455450 / [email protected]) in case of DFT readings fall outside this recommendation.

Safety Precautions


  • For paint and recommended thinners, see information sheets information sheet 1430, information sheet 1431 and the relevant Material Safety Data Sheets in the attachments section above
  • This is a solvent-borne paint and care should be taken to avoid inhalation of spray mist or vapor, as well as contact between the wet paint and exposed skin or eyes
