RECOMMENDED – for immersion exposure:
SUBSTRATE CONDITIONS • steel or steel with not approved zinc silicate shop primer; blast cleaned
AND TEMPERATURES (dry or wet) to ISO-Sa2½, blasting profile 30 - 75 μm
• 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 or power tool cleaned to SPSS-Pt3
• coated steel; hydrojetted to VIS WJ2 L (blasting profile 30 - 75 μm)
– 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 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
• 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
– for shop primer with IMO type approval; no additional requirements
– 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
• 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)
– for atmospheric exposure conditions:
• steel; blast cleaned to ISO-Sa2½, blasting profile 30 - 75 μm or
according to ISO-St3
• shop primed steel; pretreated to SPSS-Pt3
• galvanised steel; cleaned from grease, salts, contamination and
roughened up
– previous coat; (e.g. SigmaPrime 200) dry and free from any contamination
– substrate temperature should be above 5°C and at least 3°C above dew
point during application and curing
– maximum relative humidity during application and curing is 85%

INSTRUCTIONS FOR USE mixing ratio by volume: base to hardener 80 : 20
– the temperature of the mixed base and hardener should preferably be
above 15°C, otherwise extra solvent may be required to obtain application
viscosity
– too much solvent results in reduced sag resistance and slower cure
– thinner should be added after mixing the components
Induction time none
Pot life 7 hours at 20 °C *
* see additional data
