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
