    PPG - Sigmashield 880 is a two-component, high-build polyamine adduct cured epoxy coating, primarily designed for use in offshore splashzone maintenance.

    Features

    • Primarily designed for use in offshore splash zone maintenance
    • Outstanding sea water resistance
    • Excellent corrosion resistance
    • Surface tolerant and abrasion resistant
    • Continues to cure when immersed in water
    • Long-term protection in a single-coat application
    • Resistant to well designed cathodic protection
    • Suitable for application on exterior of buried pipes
    • Suitable on wet blast or ultra high pressure water (UHPWW) cleaned substrates (damp or dry)

    Recommended Substrate Conditions and Temperatures

    Substrate conditions

    • Coating performance will depend upon the surface preparation degree
    • For atmospheric service, abrasive blast to ISO-Sa2½ or minimum SSPC SP-6, power tool cleaned to ISO-St3 (SSPC SP-3)
      or hand tool cleaned to ISO-St2 (SSPC SP-2) or ultra high pressure water jet to SSPC SP WJ-2(L) / NACE WJ-2(L)
    • For immersion service: steel; blast cleaned to ISO-Sa2½ (SSPC SP-10), blasting profile 40 – 75 µm (1.6 – 3.0 mils)
    • Higher profiles (>75 microns, 3.0 mils) is allowable with appropriate coating thickness
    • Compatible previous coat must be dry and free from any contamination

    Note: Coating performance is, in general, proportional to the degree of surface preparation.

    Substrate temperature and application conditions

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

    Instructions For Use

    Mixing ratio by volume: base to hardener 75:25 (3:1)

    • Thinner should be added after mixing the components
    • Do not thin more than is required by appropriate application property
    • Adding too much thinner results in reduced sag resistance and slower cure
