PPG - Sigmacover 280 - Epoxy Primer is a two component, polyamide cured, epoxy primer that can be used as a general purpose epoxy primer, ideal for Ballast Tanks, Decks, Topside, Superstructure, Hull and Cargo Oil Tanks

Features

  • General-purpose epoxy primer in protective coating systems for steel and non-ferrous metals
  • Excellent adhesion to steel, shop primer, galvanized steel and non-ferrous metals
  • Good flow and wetting properties
  • Good water and corrosion resistance
  • Cures at temperatures down to 5°C (41°F)
  • Suitable for touching up of weld seams and damages of epoxy coatings during construction
  • Can be overcoated with most alkyd-, chlorinated rubber-, vinyl-, epoxy- and two-component polyurethane coatings
  • Suitable on wet blast cleaned substrates (damp or dry)
  • Compatible with well-designed cathodic protection systems

Recommended Substrate Conditions and Temperatures

  • Apply this product to the specified thickness as soon as possible after the surface is prepared

Immersion exposure

  • Steel or steel with not approved zinc silicate shop primer; blast cleaned (dry or wet) to ISO-Sa2½, blasting profile 30 - 75µm (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))

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 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 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)

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

  • 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 SP-16 guidelines

Stainless steel

  • The surface must be properly prepared, dry, clean and free of any contamination
  • The surface should be sufficiently roughened by sweep blasting with inert non-metallic abrasives
  • Sweep blast in accordance with the SSPC SP-16 guidelines

Concrete / Masonry

  • Dried for at least 28 days in good ventilation conditions
  • Moisture content should not exceed 4.5%
  • Concrete must be sound, dry, free from laitance and any contamination
  • Surface should be sufficiently roughened

Substrate temperature and 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%

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
