RECOMMENDED SUBSTRATE CONDITIONS AND TEMPERATURES

Immersion exposure

• 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 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
• Previous coat must be sound, 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 (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 shop primer damage or break down should
be blast cleaned to ISO-Sa2½ 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.
• 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 sweep blasted or otherwise roughened
• Previous coat must be dry and free from any contamination

Substrate temperature and application conditions

• Substrate temperature during application and curing should be between -20°C (-4°F) and 15°C (59°F)
• Ambient temperature during application at -20°C (-4°F) is acceptable; however curing to hardness takes longer and
complete cure will be reached when the temperature increases
• 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%

Galvanized steel

• The surface must be properly prepared, dry, clean and free of any contamination
• The surface should be sufficiently roughened by sweep blasting to achieve a uniform matt appearance
• Sweep blast in accordance with the SSPC-SP16 guidelines

INSTRUCTIONS FOR USE

Mixing ratio by volume: base to hardener 4:1

• The temperature of the mixed base and hardener should preferably be above 5°C (41°F), otherwise extra thinner
may be required to obtain application viscosity
• Thinner should be added after mixing the components
• Adding too much thinner results in reduced sag resistance

Pot life

7 hours at 10°C (50°F)

Note:

- See ADDITIONAL DATA – Pot life

THINNER 91-92

Volume of thinner

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

Nozzle orifice

- Max. DFT: DFT 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 must be consulted in case of DFT readings
fall outside this recommendation.
