PRODUCT CHARACTERISTICS OF SIGMACOVER 630 SIGMA PROTECTIVE AND MARINE COATING

below are characteristics of what makes this product unique.

  • Surface tolerant coating for lower grade of steel preparation
  • Particularly suited as maintenance coating for dry cargo holds, decks and hulls
  • General-purpose epoxy buildcoat or finish in protective coating systems, for steel and concrete structures exposed to atmospheric land or marine conditions
  • Compatible with various aged coatings
  • Overcoatable with most types of coatings
  • Excellent corrosion resistance
  • Resistant to splash and spillage of a wide range of chemicals
  • Good flexibility

COLOR AND GLOSS LEVEL

• Green, gray, redbrown, black, aluminum
• Semi-gloss

RECOMMENDED SUBSTRATE CONDITIONS AND TEMPERATURES

Atmospheric exposure conditions

  • Steel; blast cleaned to ISO-Sa21⁄2, for excellent corrosion protection

  • Steel; blast cleaned to ISO-Sa2, blasting profile 40 – 70 μm (1.6 – 2.8 mils) or power tool cleaned to ISO-St2 for good

    corrosion protection

  • Shop primed steel; pretreated to SPSS-Pt3

  • Coated steel; hydrojetted to VIS WJ2/3L

  • Existing sound coating systems; sufficiently roughened, dry and cleaned

    Immersion in water with cathodic protection

  • Steel; blast cleaned to ISO-Sa21⁄2, blasting profile 40 – 70 μm (1.6 – 2.8 mils)

  • Steel with approved zinc silicate shop primer; sweep blasted to SPSS-Ss or power tool cleaned to SPSS-Pt3

  • First coat SIGMACOVER 630 aluminum

    Substrate temperature

    • Substrate temperature during application and curing should be above 10°C (50°F)

    • Substrate temperature during application and curing should be at least 3°C (5°F) above dew point

      INSTRUCTIONS FOR USE

      Mixing ratio by volume: base to hardener 83:17

    • 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

      2 hours at 20°C (68°F)
